I went out to water the tomatoes this morning and found, sadly, that 3 of my tomatoes have been infested with SOMETHING that is turning the leaves yellow, curled, and with small holes. It appears to be spreading from the base of the plant. The tomato fruits seem to be unharmed. I didn't see any actual buggies (like hornworms), but there did appear to be a little "webbing" on the leaves. Most of the plant still looks green and healthy, but a good 1/4 of it is hideous!
Is this just aphids or what? I went and sprayed with an oil/detergent mix, and then I fertilized. Other advice??
Also, I have noticed that although my pumpkin plants are HUGE, the fruits set, but then they seem to wither. What is wrong? Can I fix this??
