Hi-Yield (21624) Zinc Sulfate, 4 lbs | Zinc sulfate 36% granular - Corrects zinc deficiency in pecan trees, vegetables & ornamentals - Serious gardeners

This is pretty darn good Doesn’t work on just pecan trees works on other trees we had one it looked like it was dying all the leaves were falling off about six weeks ago now it’s fall in beautiful after using the Zinc water get almost every day very very slow now we just water it once a week

Bought before works fine

I wish the bags were bigger and the price was smaller

The packaging only hints at all the potential this powerful chemical holds. I used it to create an electrolytic bath which enabled me to replate some rusty nuts and bolts.

as nexpected

Fertilize pecan trees

Quality product

Used this in the past and seems like it works good.
