Hi our magnolia grandiflora is flowering but the flowers are turning brown, not opening fully and full of black bugs.
Any ideas of treatment please?

Have you a photo of the black bugs. ?
Are they pollen beetles?
Magnolia grandiflora flowers do turn brown when they get wet as they are about to open. They only really look good in a dry spell.
Thank you.Think they might be as destroying stamens. Do I treat or leave?
