Description states it kills weeds. Making sure it is safe for trees
Pennington Pro Care Fertilizer 15-0-5 with 0.03 LOCKUP contains the post-emergent herbicide penoxsulam. Since penoxsulam targets broadleaf weeds, it could also potentially harm desirable ornamentals such as flower, shrubs, and trees. We would not recommend using this product where it could contact the foliage, roots, or branches of desirable ornamental plants.
