It's hard to imagine in mid-summer, when it's so hot and humid here, but I should already have stout brussels sprouts and broccoli seedlings ready to transplant if I want to attempt a fall crop. The seedlings that I have are pretty small, so I'll have to hope that they'll do OK.
But, I have all the seeds I need to start sowing the last rows of summer beans and squash, and gradually work my way through the sequence of planting beets, carrots, kale, lettuce, peas and spinach (not necessarily in that order!) A friend was lamenting the absence of any tomato transplants for fall in our local big box garden centers. It's a pity since it would be a great time to put in a 'second shift of tomatoes' in our warm climate. For us, as odd as it seems in a rural area, either growing your own seedlings, or ordering transplants through mail order are the primary options, unless you manage to get some at a local farmer's market.
I was delighted to read a By Design opinion piece Grow your own today in the New York Times. A city dweller, Allison Arieff reports on an urban trend (think NY, San Francisco, and Portland) of hiring an 'urban farmer' to come in and convert part of your yard to a vegetable garden, tending and picking it for you. The comments to date on the piece (and this trend) are fascinating, from raves to disparaging remarks.
I think it's a wonderful first step for Allison and her husband to start enjoying their backyard as a source of veggies (and green space), then realize that doing it themselves is even more fun. Just becoming more aware of where all of your food is coming from, how it's grown, and how it got to you is revealing.
Lots of people hire folks to mow their lawns and blow their leaves; why not hire someone (experienced) to grow vegetables, and teach you in the process?
