Last Monday I returned from a week's vacation in coastal Maine, where the highs never crossed 80 and the evenings required the wool sweaters and socks I'd long ago put away in Memphis. Before we left, my sugar snap peas were in full swing- I had to harvest from my galvanized tub garden every day to keep up with them. When we got back, the blistering temperatures had fried the poor plants and they were brown and crispy. The chickens, at least, got to enjoy the last of spring's peas.
I had prepared for the second round of crops in my tubs by pinching some of the tiny yellow currant tomatoes that grow in the church garden that hosts my acupuncture clinic and rooting the cuttings. I've watched these plants for a few years- they are vigorous (and vigorously reseed), disease resistant, and more importantly, delicious!
If you live in a climate like mine, hot now, with a long growing season, you might consider rooting some tomatoes now and planting in late July and August to get a fall crop!
