Plant fertilizer cone Question
 

So... I bought a couple of those brown cone-shaped FW plant fertilizers they have right at the counter at big al's (in the bulk bins) and now I don't know what they are called or how to use them....really hoping someone on here know what I mean and can help me! (stupid me - I fogot to ask)
I think the name begins with an L?

EDIT: Nevermind....found the receipt! *oops* "Terrapur" (Dunno where I got "starts with L" from)
