A friend of mine is looking for some feritilzer, specifically with the ratio
of 15-15-15. Can anyone please help us buy some? Any info is appreciated.
Pls email or reply here. Thank you

How much do you need? Most garden centers or plant nurseries would have
it in garden or houseplant sized quantities (i.e. small jars to bags of
several kilograms). Even generic sorts of places that sell house plants
would likely have it too. If you can't find 15-15-15, get 20-20-20 and
use 3/4 as much.

If you want tons, for a farm, check farm supply stores. If they don't
stock it, they'd likely be willing to order it for you, if you need
large quantities.
