A none-soluble fertilizer so easy to use. This fertilizer is used by Palm growers in Florida. It is a slow release for up to 10-12 months and has a NPK-ratio of 17-6-18 with those extra components such as iron and manganese.
It is almost impossible to over-fertilize your palm tree and much more safe to use than the soluble palm fertilizer. Also, this fertilizer can be excellent for other exotics in the garden such as olives and bamboos.
