Umbrella Lettuce

As it turns out, you can grow cool season crops in a completely unheated greenhouse if you give your plants an extra layer of protection.  In this case, it’s clear umbrellas covering buttercrunch lettuce, one of our favorites.  The more you cut, the more you get and it’s delicious!  We’re going to take this experiment to a higher level next year, with more indoor raised beds and a fancier second covering that is yet to be designed.  Retired engineers need something to do in their spare time…

    This is really cool. I was wondering what you typical low temps are? I’m in New England and generally colder than VA but thought that if you were at a higher elevation than I am you may get lows as cold as I do here.

      Thanks! I’d say our winter temps are similar to those in NY where we used to live but without as much snow. It’s suppsed to be 19 degrees tonight. We’re in gardening zone 7.

    Wonderful! Love the idea of extending the growing season as long as possible for fresh produce at home. Is there any reference material you used to learn about this that you particularly recommend? Thanks! Joy.

      Hi Joy! We got this idea from hearing a speaker from an agricultural school last year. He was suggesting greenhouse raised beds with typar covers, but we had the umbrellas handy. You might want to check out Eliot Coleman’s Four-Season Harvest book for some ideas. I bet your library has it, it’s been around for more than ten years.
