Stella D’oros

Question

We have stella d’oros planted in our front yard and have had them for over 15 years. They bloom every year beautifully. This year they are dying and are covered with what looks like aphids. They are turning yellow and laying over on each other. What can I spray them with and/or use on the dirt around them if we pull them out?

Answer 1

You can treat them with neem oil, which is very effective against these pests. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm
