Q&A

Couple of questions. 1- is there any variety of plants that I can’t use 14-14-14 on. 2- What’s the proper application rate per 10” hanging baskets.
It is a fantastic product that can be used on all plants. For a 10” container, it is recommended to apply 11-39 grams per container. See the label for details on application and container sizes.
I have a roof top garden in planters. Can you give me an approximate of Osmocote 14-14-14 to apply in pots. ?
It depends on the size of the planter. Can you please send in a photo to support@lawnsynergy.com?
