Growing Short-Season Vegetables

I want a greenhouse. But want and have are too far apart right now. And the beginning and end of our growing season are too close together. Like many gardeners, we want to produce as many edibles as we can during our growing season. And like many rural residents, we crave affordable, fresh produce.

We’re better off than some; our last freeze occurs in early to mid-May, and our first freeze in early to mid-October. But we all know how those predictions go. With cool, high-desert evenings, the ground has to warm up enough to germinate seeds. Add high winds and low humidity, and it’s pretty much trial and error from one year to the next!

Here are a few tips for growing vegetables and other edibles in short seasons from our attempts and courtesy of the Pacific Northwest Extension services:

  • Make sure your garden is prepped and ready for planting as soon as it’s warm enough to do so. I wrote about spring preparation a few weeks ago.
  • Choose the best spot for your garden or raised bed based on microclimates, such as along a south-facing wall to maximize heat, or where you have a natural wind break in your yard.
  • Speaking of raised beds – they warm more quickly than the ground soil. They also can drain better, but may dry faster. So consider all of these factors when selecting plants for raised beds and containers.

  • Start your seeds early enough to have nice, sturdy transplants ready. Naturally, that only works for those edibles that transplant well, such as tomatoes. If they become too big for the starter pot, transplant the entire block into a larger pot of sterile potting mix until ready to go in the ground. And be sure to harden them off for a few weeks before planting.
  • Cool-season vegetables are easier to sow in colder climates. Examples are beets, Brussels sprouts, carrots and several greens. I’ve already planted spinach, arugula and several loose-leaf lettuces in containers and in our garden.
  • Warm-season crops might need a boost, and they surely need a good start. Make sure to plant beans, melons, tomatoes, squash and cucumber after the soil temperature reaches 50 degrees. Covering them with a light, white landscape cloth can help protect them from cool night temperature and gives seedlings a fighting chance against flying and hopping insects.
  • Choose early bloomers. Some varieties mature earlier or have a shorter time to harvest. Tim really wants honeydew, which should be sowed directly in the ground after the 50-degree soil mark. We found a hybrid that says it can be harvested in 70 days, so we’re going to give it a try. If it doesn’t work, we’re only out the cost of a seed packet, the time and most importantly, the water. Look for terms such as “cold climates,” “short season,” “early to mature” or “northern gardens.”

  • Help your plants stay warm (or shaded) with an appropriate cover. Aside from row covers, you can use tires or hot caps to protect and warm young plants. Our neighbor is in the stucco business, and he has given us dozens of five-gallon buckets. My husband cuts out the bottom and they work great at protecting young plants from sun and wind.

  • Of course, here in the dry Southwest, we create troughs or wells for nearly every crop to ensure consistent, deep watering and good growth.

Finally, it’s great to get advice from local “experts.” Most are just trying to be helpful. But don’t let lore and legend trump your can-do attitude and willingness to try these tips and your own brilliant ideas!
