My husband’s got worms and I couldn’t be more thrilled. Because his worms eat food scraps and produce a nectar-like waste product – worm castings.
With vermicomposting, he’s producing a soil amendment (humus) full of more than 60 micronutrients and trace minerals to gently and naturally support plant growth. Worm castings are the excrement left by worms, and the worm tower he uses for vermicomposting makes it easy to feed the worms and harvest their castings.
Benefits of Worm Castings
Castings hold all sorts of live micronutrients that help plants better absorb nutrients from soil, especially soil with low or high pH.
The worm castings can help repel some pests such as white flies and aphids; an enzyme in the castings is offensive to pests.
Feeding worms food scraps reduces and recycles garbage throughout the year.
Worm castings do not stink!
How a Worm Bin Works
Tim purchased a Worm Factory from Nature’s Footprint a few years ago. He keeps it in a corner of the garage for easy access and protection. Vermicomposting works with upward migration. The worms move up to eat, and gravity sends moisture and castings to the bottom. Adding food at the top every so often (when worms are actively eating the last food you added and are moving to the top tray) keeps the worms continuously fed and reproducing. The worms eat paper, fruit and vegetable scraps, bread, coffee grounds and eggshells, along with other scraps. The bedding added to each level eventually breaks down into castings as well.
The resulting compost is thick, dark and crumbly. Its ready to use as soon as you harvest. Some of the best uses are to mix the castings in with garden soil as an amendment or to top dress container plants. We added castings to some of our vegetable starts last year a few weeks after planting, just loosely scratching the castings into the soil around the plants. It takes less worm compost to improve soil than regular compost. Finally, use worm castings to make compost tea.
A Few Tips
Keep the tower warm in winter. You might have to either move a worm bin or give it some heat. There are insulators made for bins. Tim hangs a lamp over the bin and sets a timer so the lamp warms the bin at night. Even if production slows, the worms are warm enough, and the food does not freeze.
You’ll have more success if you break the food scraps into manageable sizes, about the size you get when running a peeler over a carrot.
Be sure to check instructions for worm type. Red wigglers (Elsenia festida) eat and reproduce better than most, but you can use European nightcrawlers (E. Hortensis), which work well in our tower.
Store your worm castings in an airtight container and they’ll continue to break down. Just let the castings dry a little before sealing. They can be damp but not wet.
The leachate, or liquid that runs down, can be toxic. Don‘t use it if it smells bad or on edibles. Be sure to dilute it with a ratio of about 10 parts water to one part leachate.
If you’re looking for a way to get kids involved in gardening, worms are it! What fun kids can have helping care for the worms and seeing how they help a family grow food or pretty flowers for mom. It’s also a great way to teach responsibility if kids are charged with prepping scraps or bedding and feeding worms.
If you can’t spend the money on a worm bin or tower, you can find information on making your own or vermicomposting directly into a garden bed.
I just discovered this delicate, early bloomer in the past few years when friends suggested Love-in-a-Mist (Nigella damascene) seeds from our local iris farm. The foliage looks much like fennel or dill as seedlings sprout, and nigella also is called fennel flower.
Nigella Is Versatile
We grew multicolored love in a mist in our rock garden. Tim threw the seeds out in fall and by mid-spring, we had fine fern-like leaves popping up from between the rocks. Although Nigella does best in damp sandy soil, ours grew out from under rocks that make up the walls of our xeric garden. The rocks likely held moisture longer than a spot in the open might have. The rocks also trapped the tiny seeds so fewer blew away. Plus, nigella can tolerate dry conditions.
But then we tried another approach – we bought a packet of Bridal Veil (Heirloom White Nigella) seeds from Renee’s Garden and sowed them in early summer in a blank spot of our vegetable garden. This soil is far better in quality, and the seeds received consistent drip watering. The flowers were taller and stunningly white, with maroon to black centers. The plants reproduce from seeds, assuming some seedheads are left on plants at the end of the season.
Sow in Fall or Spring
Although most instructions for growing nigella say to sow in spring, you can sow them in fall in areas with mild winters. They need full sun and grow in zones 2 through 10. That worked well for us last year, but this winter has been dry and consistently colder, so I’m anxious to see how many reseeded in our gardens. The bridal veil flowers in our vegetable garden bloomed later in the year, but were planted later. Sowing the seeds a few weeks apart in spring and fall can help ensure constant blooming of nigella in summer.
Use as a Cut Flower
You can cut nigella blooms for flower arrangements, and even better, cut some of the seedheads. If you cut the flowers to enjoy indoors, leave a few blossoms on the plant so they can dry and drop seeds for the next year. If you get too many, thin them out while small. Enjoy the seedheads after flowering by cutting their stems just after flowers fade, and hang them upside down away from direct sun.
Nigella is easy to grow and a great addition to any xeric garden!
As winter drags on, birds need lots of energy and shelter from the elements and predators. The best bird habitats mix shelter, water, natural seeds and nest-building material as spring approaches. Native plants offer many of these benefits, and the more varied a landscape, the more bird-friendly it is. For example, birds in our garden “stage” their visits to feeders or the ground by moving between the thorniest rose bushes and higher trees.
Here are five plants or plant types that make birds safer and happier when temperatures drop without adding a lot to your work, or to summer watering requirements.
Replacing at least some of your turf with native grasses and other native plants helps birds and uses less water. We purposefully leave our native grasses (mostly buffalo and blue grama) long as it dies back in fall to increase shots at reseeding and filling in bare spots. The seeds also provide food for ground-hopping birds, additional food caches for jays to hide the raw peanuts we put out, and dried grass stalks for nests before the grass greens in summer.
Switchgrass, big bluestem and muhly grasses all provide seeds and nesting materials for birds. Karl Foerster feather reed grass (Calamagrostis acutiflora “Karl Foerster”) attracts birds and is a beautiful winter plant, with tall seed stalks that blow in the breeze. There are hundreds of species of the grass, and it grows in zones 5 through 9. Its water requirements are a little higher than some native grasses, but if you plant Karl Foerster grass in a rain garden or low spot, it will get more water naturally and won’t be hurt by the damp soil.
Barberry (Berberus) is a hardy shrub with small thorns along its branches. Depending on the variety you choose, you’ll enjoy deep red or pinkish foliage. The shrubs grow in zones 3 through 8 and retain their leaves in winter in most conditions. Fragrant yellow flowers emerge in spring, and the prickly branches provide good cover for small birds. You can plant several barberries a few feet closer together than recommended to create an attractive, bird-friendly hedge.
Boxwood (Buxus) normally isn’t considered a low-water plant, and I’ve seen countless examples of boxwood to form formal hedges and designs in other areas of the country. It is an easy plant to shape, and makes such a good hedge because its evergreen foliage is so dense. That’s also why birds love boxwood. Although boxwood might look a little formal for a native rock garden, we use ours as a foundation plant near our front door, where we want a more landscaped effect. Since it’s also on the north side of the house, I’m sure birds hide under the bush for cover. The boxwood’s protected, mostly shady location and slow growth habit help the shrub stay healthy with less water than it might need in a sunny spot.
Pyracantha shrubs produce berries in late fall to feed birds as temperatures drop. Also a thorny bush (sometimes called Firethorn), pyracanthas provide safe shelter for birds. What I love about the shrub is the diverse ways you can use it in a Southwest landscape. Leave it to grow naturally (maybe with some shoot trimming after rainy summers) or shape it like a hedge. We had several growing along a distant fence and Tim moved one to the front of the house. The pyracantha transplanted without a blink and just a few scratches. We leave the remaining two out in the yard in their natural state and shape the one in front of the house. I get to see the berries from my kitchen window and saw a Stellar jay eating them this past fall.
Many native shrubs attract birds in winter. Berries, seeds and bushy cover all support wildlife. Ask your local nursery or master gardeners for the best low-water plants in your Southwest zone.
Gardeners in New Mexico, Arizona, Texas and surrounding Southwestern states face unique challenges. And though climate, zone and even drought conditions can vary from one area of each state to the next, we have some common issues:
Even when our regions are not officially in a state of drought, Southwest gardeners know water is a precious resource that we must protect all year.
Weather extremes are pretty common, especially where mountains meet foothills or plains.
Our states’ populations are highly rural. Although we’ve got plenty of large cities, rural gardeners live long distances from the services and products easy to come by in urban settings. So, sometimes we just have to get creative.
Heat is a major concern when growing throughout most of the Southwest.
But help is on the way, and I’m honored to be a part of a team offering a new source for Southwest gardening, along with Ann McCormick of Ft. Worth, Texas; Noelle Johnson of Phoenix; and Jacqueline Soule of Tucson. We want to make Southwest gardening fun and easier for our friends, neighbors and clients.
Join us as we offer information, ideas and sharing specific to gardening in the Southwest on our new blog, Southwest Gardening.
The new year is almost upon us, but gardeners don’t have to wait until spring to dream, plan and even shop for new plants.
You can take some time in winter to plan your garden. Doing so usually cheers my mood and makes me feel like I’m getting something done, even if I can’t do much outside. Here are a few tips for Southwest gardeners for winter planning and shopping.
Check Out New Plant Introductions
Each year, breeders offer new plants adaptable to conditions or resistant to diseases. Many independent testing organizations and growers conduct trials to see how plants fare in harsh conditions such as heat or drought. A favorite regional source is Plant Select in Colorado. The nonprofit organization tests and creates plants for the Rocky Mountains. You can search or browse their plant selections for zone, soil type, sun exposure, water needs and other characteristics. A new 2017 selection is the Sungari redbead cotoneaster (Cotoneaster racemiflorus var. soongoricus). The shrub is a hardy plant and fall stunner in a xeriscape.
All-America Selections also releases trial information on ornamental plants and vegetables each year. Although some of the plants are not suited for New Mexico gardens, AAS includes regional winners for the Mountain/Southwest region. For example, its 2018 winners include Mexican Sunrise Hungarian Pepper F1. This past summer, I sowed 2017 national winner Dianthus Interspecific Supra Pink F1 seeds in a garden bed and the plant bloomed well into fall. You can find AAS winners at retailers that carry national brands such as Bonnie and Burpee plants or seeds (Johnny’s selected Seeds or Territorial Seed Company).
Regional growers and local nurseries often carry new plant introductions. Typically, you can learn about new plants by subscribing to the company’s newsletter or by following them on social media. High Country Gardens (whose chief horticulturalist, David Salman, is from New Mexico) recently released a list of new plants the company offers in 2018.
Finally, the Sunset Western Garden Collection is designed specifically for Western gardeners. Sunset lists a collection of waterwise plants, but you might have to do some research to find out where to buy the plants you spot there.
Order and Review Seed Catalogs
Growing plants from seed takes a little more work, but can save you money. And some plants do better grown directly in the ground (cucumbers and squash come to mind). Even though you’ll have more success and save water by growing plants suited to your region, it’s fun to shop for rare or unusual annuals for containers or other special spots in your garden. It’s much less expensive to buy seeds for plants that probably won’t make it through the winter.
Most seed companies ship catalogs for free to anyone who requests them and I’ve been receiving mine since before the holidays. In addition, you can find online versions of most seed catalogs. Flipping through catalogs can give you great ideas about new or unusual plants or even inspire where to plant them or ideas for companion plants for a particular flower or shrub.
Read and Research
Catalogs are one source of plant ideas, but local and regional gardening books and blogs should be your go-to sources. Combining information on plants featured in your favorite gardening books with catalogs and new introductions can help you begin planning and shopping.
In your research, look for ideas such as drought-tolerant plants for easy care, plants for birds and pollinators, or colors and textures you long to add to your garden. Think about herbs and vegetables your family loves and see if you can grow a variety within your space or time constraints. And always read books and websites with a critical eye for credible information and plants most likely to grow in your zone, soil type, sun exposure or water availability.
If you don’t have a good gardening book specific to your state or zone, find out if your local master gardeners have published a plant or gardening guide. And check out my Resources page for books and links on gardening in New Mexico, xeric gardening and other topics.
Shop Locally and Online
Some gardeners prefer to touch and see plants in person, at least to decide on colors or shapes they like. Just beware that some chain stores offer plants each year that aren’t suited to your region or at least offer fewer plants tested for Southwest and xeric gardens. For example, no retailers in New Mexico offer Plant Select products, but High Country Gardens sells Plant Select through its catalog and online store. Shopping, or at least researching, online also can save time. Many online catalogs have search filters. You might be able to search by plant name, bloom color, bloom time or average temperatures and rainfall.
Many online nurseries let you order now and then ship your plants at the best possible time in spring for your zone. So, there’s really no reason you can’t get a head start. Happy plant shopping!
Winter has come late to New Mexico this year, and that’s OK with me. The problem is even when it’s sunny in winter, we have fewer projects we can do so we feel productive and in touch with the soil and plants. So I thought about a few ideas to lighten my winter doldrums and decided to share them.
One: Take a drive or hike, or some combination.
As soon as fall hit and gardening slowed down, we began to visit spots we seldom get to see during the growing season. We drove up nearby mountains and about an hour away to a walk among stunning petroglyphs. My mood improves from endorphins and simply being outside. And we always see a few native plants we’d like to identify, even if they’re at the end of their growing season.
Two: Grow a winter-blooming indoor plant.
Aside from the pretty holiday mascot, the poinsettia, you can grow a Christmas cactus or amaryllis. I received a beautiful gift of paperwhites (Narcissus) in a clear glass bowl one year. One of these days, I’ll try to force my own. And if you have a warm, sunny window, why not bring in a few of your potted plants? Geraniums can continue flowering in the right conditions, and we brought a shade-loving container with coleus and begonias inside. They might get leggy before the winter’s up, but they make me feel more in touch with summer.
Three. Feed birds and other critters.
Leaving the garden a little messy might seem like a bad idea, and it is tough to watch the demise of your favorite stalks and flowers. But birds continue to feed off the seeds of many plants or seeds spread in fall and early winter winds. Once the seeds fade, birds need a little extra help to get through cold winter nights. We hang suet and a sunflower seed feeder and set out raw peanuts for the jays. I want to keep the birds coming so I have something fun to look at from my window when the sky is gray and the garden mostly brown.
Four. Start a project, like a bee house or raised bed.
Last winter, we replaced the door on our shed, completely revamped a large garden path, created a dry river bed, and took on lots of other fun projects. In fact, we took on so many that we have to come up with some new ones this year. But vegetable gardens might need new or improved fencing or other design and maintenance. Putting in a new paver path or dry river bed are projects that come to mind. You can build a raised bed or make a bee house or butterfly waterer (puddling pool). Or you can repot some of those succulents and other houseplants you tend to neglect in summer.
Five. Make and give garden-related gifts.
Some winter projects turn into gifts for family, friends or co-workers. I don’t have a perfect crafting style, but I know people appreciate gifts from the heart, time and garden. We’ve made lavender sachets, pressed flower arrangements and outdoor lights. You can even pot up some plants in homemade containers.
And on a snowy, cold and dark winter day, spend a little time by the fire drinking an herbal tea and reading a gardening book, magazine or catalog. You can relax, plan and dream!
In the arid Southwest, most plants don’t like an abundance of rainfall. Xeric plants such as lavender or rosemary can be damaged or die from too much moisture in the crown or roots. Sometimes, the location a homeowner places a plant affects watering and alters the plant’s ability to thrive as as it should for the zone in which the gardener lives.
Other times, conditions change. That’s what happened in an area near the foundation of our home when we expanded our back patio. We found that excess water from the patio and rain barrel near the edge redirected water during rains. During monsoon season, a blue mist spirea (Cayopteris) and cotoneaster began to show signs of overwatering.
We needed to divert some water away from the two bushes and recognized the importance of either collecting or directing rainfall. We couldn’t afford a large rain cistern, but we had one natural resource in abundance—rocks. So we built a dry river bed, also called a dry creek bed or dry stream. The project was a way to change up the landscape and divert extra water down to our lawn.
Step 1: Move plants
The first step in our project was to move the plants. We divided the spirea and kept the largest portion to replant; we transplanted two smaller sections on a ditch bank back in our orchard. We ended up removing the cotoneaster, which was beginning to overgrow a path we us regularly and had large areas of rusted, dying foliage.
Step 2: Design hills and valleys; test
We next built up a small hill or berm as a new spot for the blue mist spirea and a new cotoneaster bush. This would allow us to control the plants’ watering better. We dug and scraped a river-like trough to help water drain down and toward the grass. It didn’t take much depth to get water from the patio to the grassy area below. Getting the depth and flow right took some trial and error with a garden hose to simulate the rain and made a few adjustments where water backed up.
Step 3: Add rocks
We already had a pile or two of rocks we’ve dug up. And there is no shortage around here. The first step was to cut and lay down black weed barrier, followed by large rocks along the top and side of the dry river to hold the fabric, direct water and add a decorative, but natural effect. This was followed by addition of medium and smaller rocks. We gathered the small rocks throughout fall and winter, sometimes a few at a time, to fill in.
Step 4: Plant!
All our hard work was rewarded with a new area for planting. We had the two bushes, and moved a small pine leaf penstemon to a lower part of the berm. We purchased several grasses, some perennials and a few annuals to fill in. Then we got lucky and had a volunteer blanket flower crop up in just the right spot. We stopped the rock design a foot or more from the house in most spots and used pecan mulch around those plants. Here’s why: Rocks reflect sun and heat and my office window is right above the dry river bed area.
Pulling out the large cotoneaster and adding rocks has intensified the heat in my office. I know that will ease once the plants grow to maturity. And the heat might be welcome on a cloudy January day. We also lost the first cotoneaster planted. It could have been any of a number of causes, but we likely made a common mistake: not watering enough. I was so concerned with keeping this plant from getting too much water that I failed to account for how much would drain away from its roots and the immaturity of the plant. Our second attempt is going well. It’s also easy to change the flow of water just by placing a rock or two in a certain way. So we check the flow when it rains to look for pooling of water.
Overall, we were pleased with the look and function of the dry river bed. The native grass below it turned green earlier than normal and we stopped problems from mud and overwatering of bushes in the area. This is an easy and inexpensive garden DIY project!
As fall temperatures drop, there’s still plenty to do in the Southwest garden. In most areas of New Mexico, freeze hits by mid- to late October. But plenty of sunny days hit in fall here so gardeners can get outside and take care of these chores before winter arrives:
If you still have any vegetables ripening, better harvest them now. Tomatoes and winter squashes can finish ripening inside. If you haven’t harvested and dried herbs, now is the time to trim them back and get them ready for use in the kitchen. Some vegetables, such as kale and carrots, can stay in the ground a while. You can preserve some vegetables with help from extension office publications or other credible sources that address flavor and safety of canned or frozen foods. Finally, I like to pick flowers still blooming and place them in a vase inside, just to make me feel better about the season ending.
There is some debate about what to leave in the garden and what to throw out. You definitely want to throw out any weeds or diseased plant cuttings. Compost healthy cuttings. We even laid some carrots that were too big for our taste out on tree stumps for deer and other critters to eat. It’s personal preference to leave some debris on the ground to naturally compost in place. But if the debris hides unwanted bugs or spores, it’s not a good idea. I usually clean up most plant debris and then use straw or leaves for composting.
3. Preserve Bulbs and Seeds
Check a local gardening book or online to find out how to dig up and overwinter bulbs that can’t handle cold temperatures in your area. In zone 6B in New Mexico, we leave iris, daylily and allium bulbs or corms and should dig up gladiolas and dahlias. Usually, the bulbs just need to be kept cool and dry. You also can preserve seeds from flowers and herbs such as dill or cilantro for cooking or replanting.
4. Leave Some Seeds
Not all flowering plants need fall trimming of spent seed heads. Many can make it through winter and wait for summer trims. And birds love dried up seeds on sunflowers, cosmos and other flowering annuals. Plus, by leaving the seeds on, you increase the chance that some native grasses or flowers will reseed.
5. Evaluate Plant Placement
As you clean up and assess how plants look at the end of their growing season, you can evaluate plant placement. For example, some of our green beans did not fare as well as last year. I believe the spot I planted them in this year got more late summer shade from a neighbor’s tree than I anticipated based on early summer sun. Some plants might have grown too large for their spot or get too much water from runoff. Take some notes and consult local sources so you still have time to decide whether you can move them this fall. Or plan where they’ll go in spring, especially before buying new plants!
In New Mexico, we mulch for two reasons: to conserve water and cool roots in summer and to warm roots during cold winter. I typically mulch as part of fall cleanup and near the time of the first freeze. Most plants that are native and appropriate for your garden can get by without mulch, but it helps protect tender plants from hard freezes in winter. Mulching needs to be a few inches thick to insulate and to cut down on weeds.
7. Protect Plants
Some of my gladiola bulbs came back and rebloomed without being dug up. But I mulched them pretty heavily with leaves. In addition to mulching, you can put buckets around plants to help keep them warm, especially in winter wind, or to keep deer from destroying them (adding a “lid” made of chicken wire or similar material that lets in sun and moisture but not curious critters). Plants in containers that are tender or annual in your area need to come inside, We move outside containers against a south-facing wall for warmth and to protect against wind.
8. Empty Containers
It’s time to empty all those containers with edibles and annuals that are dying back. You’ll need fresh potting soil next year and it’s better to store containers empty. We empty soil from our containers (unless the plant had a disease) into garden beds and large stock tank containers that need soil. You can also save potting mix in plastic sealed containers, but it should be mixed with fresh potting soil and compost when replanted in the spring.
9. Amend Soil
If you have new garden beds or some that need better soil, fall is a good time to improve soil health. Adding some compost gives it a chance to break down, as does covering beds with leaves that fall from trees. And it makes the spring preparation easier. There are many ways to amend bad soil, such as planting cover crops before frost or having a soil test so you know how to better balance pH in your growing beds. But gardeners learn to tell when soil is compacted. It’s hard to go wrong adding a little organic matter in fall.
10. Enjoy Time Outside!
Fall is a favorite season for a reason. Cool nights and warm days make it hard to stay inside, even when there are few chores to do. And enjoying even the final flower blooms before frost arrives is part of the reason you work hard to make your lawn and garden look nice.
Soak it all in and dream about spring, when you will feel renewed energy and enthusiasm for garden chores.
Sometimes, a home-grown tomato is so pretty that I hesitate to pull it off the vine. I’d rather take photos, smile as I stroll past the plant or point out the healthy fruit to anyone willing to listen.
Of course, watching a vegetable you started from seed grow into a healthy plant is a reward in and of itself. But it’s even more rewarding when the plant provides fresh, delicious and healthy food for you and your family (or friends and neighbors!).
What’s more, harvesting fruit helps the plant continue producing, sending energy to develop, ripen and flavor fruit instead of continuing to feed overripe ones. Here are some tips on when and how to harvest fresh vegetables in the garden or a U-Pick site, courtesy of the Home Garden Seed Association and my experience (including plenty of mistakes).
Color helps cue gardeners on picking tomatoes, which should be a deeper red than the ones you see in the grocery aisle. But color can be a tough cue when growing some varieties, such as yellow tomatoes. We have a few Midnight Snack tomatoes courtesy of All-America Selections and the National Garden Bureau. The delicious snack-sized tomatoes have an indigo color on top (and the fruit has extra antioxidants). You just feel the fruit and check for reddening on the bottom to make sure it’s ripe. Once a tomato feels somewhat soft when you squeeze it gently, it’s probably ready to eat. Just twist it slightly from the vine and it should give. Be sure to store tomatoes in a cool spot in your kitchen, but not in the refrigerator.
Cucumber fruit seems to mature all at once, and the best way to know when to harvest is to have an idea of the fruit’s mature size from seed packets or through trial and error. We often note that the spiky part of the peel loses some of its sharpness at peak ripeness. When in doubt, though, opt for early rather than late. Cucumber seeds get large and tough and the fruit less sweet the longer the fruit stays on the vine. Use scissors or shears to cut the cucumber from the plant; avoid twisting it off. Cucumbers store best dry in the refrigerator. I keep mine wrapped in a soft towel and wash them when I’m ready to eat them.
Carrots can begin to lose sweetness if left in the ground too long. Gently swipe away some dirt to check if the top (shoulder) of the carrot is bigger than about half an inch. For most varieties, this is a signal it’s ready to pull. Carrots tend to vary more than other fruits at harvest, especially if they have not been thinned adequately. But the taste of any nearly mature carrot from the home garden is so much better than store-bought carrots, regardless of its appearance. Carrots also store better dry, so either leave the dirt on and pack them in a vented plastic bag or let them dry completely after snipping the leaves just above the shoulders. I’ve found that our carrots store best in the ground (up to a point) and I only harvest what I need every day or two.
Beans and Peas
Harvesting beans is one of my favorite activities. I like looking for the elusive pods under the leaves. It does require two hands, however. You need to hold the stem of a bean or pea as you pull off the fruit to avoid breaking the stem and pulling off immature neighbors of the mature bean. I set a basket on the ground or hang a used grocery bag on my arm to free up both hands for harvesting. Pick beans while long and slender and before lumps form in the pods. Snap peas are best when peas are just beginning to form in the pod, but are not yet mature.
Most lettuces taste best when leaves are four to six inches long. I love cutting loose-leaf varieties because you can harvest them two or three times. If a loose-leaf or head lettuce looks elongated, it’s getting to be too late for optimal flavor. Cut outside leaves of loose-leaf lettuces first, and cut head lettuce at the base of the plant, just above the ground. Wash and dry lettuce immediately; spinners are great for this. Store in a plastic bag that is closed but has plenty of air inside. I also sometimes add a paper towel to absorb moisture in the bag. You’ll be amazed how much longer your fresh lettuce keeps compared with prepared bags!
Whether growing sweet bell peppers or New Mexico chile peppers, it helps to learn the mature color for your variety. The good news is that peppers usually have a decent flavor even when immature, although the skins might be a bit tougher. So know enough about your pepper to watch for its expected mature color and pick as soon as it turns. Leaving peppers on the plant too long slows production of new fruit. All pepper types come off the plant easiest when fully ripe. Store peppers in a bag in the refrigerator crisper. With green chile, I wait until I have enough peppers to roast and then freeze them.
Ah, the giant zucchini. Big enough to feed a family of 10, but not as sweet and tender as the one harvested at about 5 to 7 inches in length. Cut all squash fruit with snippers or a knife; don’t twist it off the vine. Winter squash should be ripe when the rind loses its shine and you can scratch the rind without puncturing it. Wipe squash clean with a dry towel; don’t wash before storing. Keep both summer and winter squash in a dry, but well-ventilated spot about 50 to 68 degrees. If you place it in the refrigerator, put it in a plastic bag in the crisper drawer.
Harvest kale and chard much like loose-leaf lettuce. You can begin to harvest outer leaves when they are about four inches high, cutting them about one inch above the ground. Avoid cutting the center tip of the plant, which can stop growth of new leaves. Wash and spin kale and store it in one of the coolest spots in the refrigerator inside a ventilated plastic bag.
In general, seed packets and other materials give you an idea of a fruit’s maturity date, but it varies from region to region and from one year to another.
Most vegetables are better harvested in the morning when crisp, healthy and dry. Or you can pick what you want just before preparing your meal. One final note: When harvesting several different vegetables, have a few containers handy. It’s no fun picking green beans out of lettuce leaves, and squash or cucumbers can flatten a juicy tomato.
