August Challenge: Homegrown or Home brewed Grand Finalists in Let's talk about pics Posted September 4 5 hours ago, MizBrown said: I was in a community gardens group in Philadelphia and one of the other gardeners had a cold frame made of used windows over his bed, if I remember correctly, and had surviving greens of various kinds throughout the winter. NYC is 90 miles north of that. Should be able to grow cold hardy greens through most winters: kale (I had some Russian kale overwinter without protection there), turnip greens, some cabbages, bok choi, and possibly oriental radishes. Completely year round at least as far north as Philly. Fruiting crops like tomatoes and peppers, probably a few weeks extension, though there are some organic tricks like planting in compost over horse manure that give some warmth for a bit long. Starting plants or protecting plants from late frost, yeah, but the real thing to do is use a cold frame for greens. I used to raise a few bok choi plants in an unheated porch in rural Virginia, and have seen collards in the ground still green in December in Washington, DC. Some plants can freeze and recover. Thanks so much for the info! We saved only one old window when we replaced ours to use as a frame - wish I'd saved more but I bet they are not too hard to find. I'm an hour north of NYC so it's a tad colder here but I bet those greens would stay for a while, at least into November. I was going to grow kale but with many rabbits around it seemed like it would be a lost cause, but it's one of my favorites! A cold frame would do double duty as a great way to protect greens from our resident rabbits in the warm months, provided I dug down and used some chicken wire in the ground and made the side walls tall enough that they couldn't jump over. I picked a bunch of okra today and am going to try my hand at making gumbo. It's been fun to grow food and I'm inspired to do more next year. Took a ton of photos today as I harvested my few veggies and picked some flowers. Thanks again for the info. I knew there were many experienced gardeners here. I bet where you are now you can grow some amazing tropical plants year round!
