    Not for New Plant Starts

    By Robert on 02/17/2023

    I was happy to see Osmocote available, but perhaps chose the wrong type for certain purposes. In the past, formulations were easy on new plant starts and I presumed this would be as well. The time release portion seems to be minimal, there are none of the green small spheres I associate Osomocote with. So, the product was great for my citrus and trees, but burned my new strawberry plants. I would get the higher grade Osmocote for new plants the next time.
