Currently I have 6 grafted plumeria plants that I purchased from Florida Colors nursery. There instructions for fertilization include using a Ozmocote balanced fertilizer. I'm currently using Osmocote 14-14-14 and I have not been including Aluminum Sulphate. Is this Aluminum Sulphate necessary for growing healthy grafts? FYI, this Osmocote is a time release fertilizer.
Please let me know
Thank you....
