On a small second floor balcony I have planted several herbs along with a few flowers in a container. There is also a yew about 3 ft. tall in a separate container. There are aphids mostly on the basil in the herb box, but the yew is the biggest problem. It has them extensively throughout the interior of the plant. The advice I have read suggests oil-based remedies but specify that the plant should not be in the sun throughout the treatment. I don't have that option. However, since the yew is very dense, maybe the sun couldn't get in deep enough to burn the tiny leaves. They are all in the sun for at least 6 hours every day. I don't have a water faucet there either, so spraying with a hose isn't possible. Is there something else I could spray water with that might be effective and is there some other home-made or store-bought remedy that could do the job? Thank you!
