Ok,you can laugh,but I always like EB Stone's brand ferts. Premium prices...but whenever I've used it.. I see a flush of deep green come over my palms,tree ferns and Mango tree in a matter of days.The drawback is the expense.

The funny part is...it has bat guano. That's the only ingredient I see on the the label that I don't see on other brands.

Haha! I'll look into that one. Thank you!

Which EB Stone do you use?

Dr Earth is also good.

Mostly the one for "Tropical's"...but some I bought for Tomatoes was down to just a handful..so I tossed under the young Mango tree..and,again that nice dark green flush came over the tree over the days.
I once was in the profession of plant growing,and mentioned that on a trade online journal. And some said,that they thought it was the type of iron used in the fertilizer. All I can say is,ten years later..I still see better results with EB Stone..and I know its a hoot to say bat guano..but whatever the exact reason,its good..but premium priced,stuff.
