I read that it's the azadirachtin in neem oil (only in cold pressed, not processed) that really works, but you have to treat early with a soil drench so the plant can take it up into the leaves and mess with the aphids' hormone receptors. The pure neem oil that I have solidifies at cold temperatures (basically below like 80, I think), and I'm wondering if it is possible to crumble up the solidified oil into pellets and add that to the soil in the spring before planting?
