Aphids and Tomatoes
Two of my three potted tomato plants have aphids. I have used a strong spray of water to knock them off but notice them returning within 6 hours or so. Can I spray water enough times to get ahead of them and keep them off, or, is there another alternative?
Do sunflowers and zinnias host aphids? I have these in the direction of my water spray! Dislike aphids from my past experience with them!
