this fertilizer is very good. All my flowers and all my trees are very beautiful and well grown. I put a tablespoon or two around everything I have in my little garden. Once a month or two. maybe it's a lot, I don't know, but I haven't had any problems so far, I'm very satisfied. Thank you very much and I really recommend it, you won't regret it. I'm sorry for this review in English, but my Japanese is not good. You can translate with google translate.
