Great for landscaping and shrubs!
By Arobinson on 09/29/2023
I've adopted a 2x a year fert program for my trees and shrubs and this product is a key part of it. I do a light application of 0-20-20 late summer/early fall and then late Feb do an application of slow release Osmocote. The plants are much healthier and I have had fewer issues with disease and insects since adopting this regimen.
