Sweet Gum and other Nuisance Fruit Prevention

Posted by John Fulton -

With ethephon applications for nuisance fruit removal (such as on sweet gum trees), the key is in the timing. The application must be made during flowering, but before the fruit set in. For most flowering trees there is a 10-14 day window of opportunity. Sweet gums are a little tricky since there are no showy flowers involved, so effective sprays should occur just as new leaves begin to emerge. Sprays should leave leaves wet, but not to the point of dripping. Good coverage of the tree is needed, so keep in mind the size of the tree when you are weighing this option. There are injectable products available, but must be applied by a professional. The injectable products have not been as effective as the sprays. This means you'll have to really hurry to have any control on sweet gums this year.
