Q.Plum Tree Pests

Anonymous added on March 28, 2014 | Answered

I have a Moyer prune/plum tree that has tiny, lime green balls collecting en mass on the blossom buds. I wash them off with a hose, but they keep coming back. They are not the same color nor look like aphids that may come later. What are they and how do I control them? Thank you.

It sounds like aphids. These pests are actually quite common on plum trees and may be green or black in color. We have found that neem oil is both effective and safe when it comes to treating or preventing aphid attacks. You can learn more about neem oil and aphids by reading the following articles: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm, https://www.gardeningknowhow.com/edible/fruits/plum/control-leaf-curl-plum-aphids.htm
