I am growing some leaf lettuce in a south facing window. While doing my first harvest yesterday, I noticed aphids under the leaves. How can I control them and still use the lettuce? This is of special concern since I am currently building a solar greenhouse. I hope to be able to control them in it when it's completed.
Ladybugs will take care of them in the GH but I don't think you want them in the house though. Rinse the lettuce a couple of times in salt water. That will take care of your current problem. John
I fought those fiends this past winter/early spring. What I found to work the best was a combo on Neem Oil and Safer Soap. I used a garden sprayer as I had hundreds of plants but being able to pump up the pressure and spray the undersides of the leaves as well as the top worked fantastically. Took about a week to eradicate them.
