About Crab Apple Trees

Question

Hi! 4 months ago I sprayed my roof with Spray and Forget roof cleaner. I accidentally over sprayed on my crab apple trees. To be safe, I did not use this Fall’s crop of apples. Would it be safe to use next year’s crop? Spray and Forget roof cleaner is toxic, but would it affect next year’s new crop of apples? Thank you

Answer 1

The product insert says it is biodegradable, no harsh chemicals, and won't harm plants; and especially since you are waiting for the next season's new growth to consume the apples, it should be fine. The label warning is for irritation if the spray gets in eyes or on skin.
