Will I have to reapply every year? What effect will Florel have on hostas, irises, lilies, growing under the mulberry?
Monterey Florel can be used on any plants that flower, including ornamental mulberry trees, to prevent fruit development. That being said, it would be best to cover nearby desirable flowers in the area when spraying so that you do not suppress desirable flowering plants. Since this product is absorbed during bloom, it should not affect grass and other plants that are not in bloom at the time of treatment. You do need to reapply Florel each time the target plants flower to prevent the next fruit set.
