Hi-Yield (21624) Zinc Sulfate, 4 lbs

I need this for my pecan tree here in Houston and used to be able to get it locally, but now I can't and just order on Amazon. Fast delivery~@

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

This product was exactly what was needed for my Texas heritage pecan trees! We love our large round nuts. So easy to apply and covers a large area

I have used this product for 1 growing season. Our trees are now producing pecans that are good quality. I cannot rate this particular order since it has not been delivered as advertised.

as nexpected

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.
