Blistering heat in the vegetable garden
I'm just about ready to conclude a very successful spring gardening season as the 100 degree heat is starting to set in, causing the lettuce to bolt, the leaves to wilt, and the insects to come in large numbers. My tomatoes have given me lots of fruit all through spring, more than we can eat!, but now the garden is out of balance with these temperatures and the fruits are pretty much all misshapen or covered in insect problems at this point.
Before I pull up my unproductive plants and get ready to start fresh for the fall, how do you carry your vegetable garden through the blistering heat of summer? I have three fairly large raised beds, and I'm considering growing a cover crop to enrich the soil and keep the yard looking green. What should I do in the garden between now and when the heat starts to let up?
