Shelter Me: Keeping the Kitchen Garden Warm and Productive as Temps Drop…

Basil and Calendula cozy up beneath a misty dome in my garden…

The first frost of autumn sparkled on my lawn when I awoke Saturday morning. And although it wasn’t a true ‘killing-frost’ —the morning glories slipped right through Jack’s chilly hands— a few things were nipped here and there in my potager. Most of my tender crops are now covered with hoop-house cold-frames —mainly tomatoes, peppers, basil and other herbs— and later, the cool-season crops like spinach and lettuce will be covered as well…

Tomatoes, ripening inside the hoop-house cold-frame in October, are safe from Old Jack Frost

Beneath greenhouse-grade plastic, purple and green basil, tomatoes and other herbs are protected from chilly nights, and given a ripening-boost during the day

I will be enjoying these ‘Lemon Boy’ tomatoes soon —not fried and not green (though that IS an excellent way to use them up!)

Last year I posted a tutorial on building hoop-house style cold frames, and if you have a free afternoon and some basic carpentry tools, I encourage you to give them a try (click to here to see tutorial post). I now have four hoop-houses in use, and although these miniature-greenhouses are unheated, they actually get quite toasty inside during the day, and the temperatures stay well-above freezing overnight. To keep things from getting too hot, the temperature inside each of my hoop-houses is moderated with a easy-to-install, automatic back-vent. Of course later in the autumn, unless I provide supplemental heat, these tomatoes will eventually succumb to overnight cold. But other crops —including lettuce, spinach, arugula, kale, chard and broccoli— can make it straight through the Winter Solstice in an unheated hoop-house (and even beyond in some years)!

There are many other ways to extend the vegetable growing season in cold climates, and I will continue posting ideas on how to stretch that post-frost ‘Indian Summer’ for as long as possible. Also, keep in mind that even if you don’t fancy the idea of a building project yourself, you can easily purchase cold frames, kits and other garden shelters from companies like Gardener’s Supply Company online.

Have you had a killin’ frost in your area? Do you try to keep things going past the freeze?

Sungold and bright red cherry tomatoes will continue to ripen beneath the plastic, well past the hard-frost
