It looks like the heat is starting to take a heavy toll on my container garden's vegetable production. We've now had many consecutive days in the 105 degree range, and 100 plus degree days will likely be the norm until September. It's getting pretty uncomfortable out there for human and plant alike.
My tomato plants are really showing the heat's impact. I haven't noticed any new tomato production in about a week now. The growth rate of tomatoes already set on the vine seems to have slowed tremendously, with ripening occurring at a much smaller size. The plants themselves are still growing, but the fruit may be finished until cooler weather arrives. My dilemma is whether to try and keep the vines alive until Fall, or pull them and then set out some early producing varieties sometime in late August for an October and November crop.
While I'll try and grow a Fall tomato crop, I've decided against any further attempts at growing beans in this location. Back in late February, I planted several lima bean, green bean, and black-eyed pea plants. All the limas and black-eyed peas died before producing anything. The green bean vines, by contrast, grew like mad until the temperature consistently topped 90. After that they stopped producing any beans, and showed signs of severe stress. I think location played a role in this, as the trellis to which I trained the vines was very close (about an inch away) to a Sun-heated wall. Although I didn't realize this at planting time, this wall gets surprisingly hot during the mid afternoon. This added heat source greatly exacerbates the problem of plant overheating. As a result, the six surviving vines have produced a whopping total of nine bean pods.
Beyond the recent slow down in tomato production and the problems with beans, everything else seems to be handling the heat well. I'll keep you updated on both the tomatoes and these other plants in the coming days.
