Yes, there is an Osmocote made for trees and shrubs and it is often used by the nursery industry. You can also safely use regular Osmocote on trees and shrubs as the plants will absorb the nutrients that they need slowly and the Osmocote will not burn the plants. If you prefer to use the formula made for trees and shrubs which is often sold in larger containers you may need to order it online as the typical garden center or nursery does not carry this product. Keep growing, Marianne Binetti
