Q.Magnolia Bugs Have Some Kind of Bug

Anonymous added on May 20, 2014 | Answered

I planted several magnolia trees over a year ago. I learned that a bug is attacking them and was told to spray them with Neem oil. I have done that three weeks in a row and they seemed to be okay. That was last year. Now it looks like they might be getting dark again under their leaves and I wanted to spray them again; however, they are putting out new leaves and blossoms. Will the Neem oil harm the new leaves and blossoms? Also, I have just planted three younger Bald Cypress trees very close to one of the magnolias. If I do spray the tree with Neem oil, will the overspray harm the delecate leaves of the Bald Cypress? I know that I need to spray either very early or late in the day away from heavy sun harming the leaves.

The Neem oil will not hurt the new leaves or blossoms. It won't harm the other nearby trees either, as it is safe to use for plants, people, animals and even pollinators. It only targets the bad insect pests. Neem oil also doubles as an effective fungicide, so it can help with any fungal issues that may crop up as well.
