Keep pecan trees healthy and productive. Prevents and corrects the nutrient disorder, Rosette, in pecan trees. Zinc Sulfate is critical to growing pecans where low soil-levels of zinc stunt tree growth and cause malformed nuts. May be used as a soil additive or fast-acting foliar spray. For best results, apply foliar spray in early spring, when leaves are tender. Only use as needed, as instructed by product label, and do not overuse.

  • For use as a foliar spray: 1 tablespoon per 3 gallons of water
  • For use as a soil additive: 1-3/4 lbs. per inch of trunk diameter

The soil in my nut orchard is an old farm meadow and has been untreated with anything for a dozen or more years. This will boost the soil's ability to support the nut orchard while the other nutrients are being added.

I had used this on my Apple Trees for years. They decided not to sell it anymore. Nothing works as well as this product. I jumped up and down when I saw it be sold again. Thanks
Sharon W on Oct 10, 2019
I had read several good reviews online for this product. I have three young pecan trees that require Zinc Sulfate and this is the brand that everyone was suggesting. I???ve noticed a huge difference in my trees since using this. They really perked up and came to life. This is my second bag.

Knowing absolutely nothing about the propagation or growing of pecans, I relied (exclusively) upon your advice regarding the prevention of stunted growth and malformed nuts, due to low soil levels of zinc."

Diagnosed as zinc deficiency. What is best treatment- zinc chelate or zinc sulfate?
Jim G on Jan 26, 2020
BEST ANSWER: I used this on my young Stark pecan trees to increase yield. I just made a band to this product around the drip line in the early spring. I did have a better yield that year. Didn't use it last year and had no nuts at all, but as I didn't have any peaches either, assume no crops were weather related. Will try this stuff again this year.
is this product the same as NZN?
MIKE D on Mar 9, 2019
BEST ANSWER: No, it is not. NZN is a commercial nitrogen/zinc formulation; HiYield is zinc sulfate and is intended for use on pecan trees.

We bought some zinc. how do you get the pelts to desolve ?
kay s on Apr 15, 2017
BEST ANSWER: I use these pellets to feed my persimmon trees. After working the product into the soil I see the pellets for some time until they eventually do dissolve. The pellets are very concentrated so it takes time for them to fully disappear which, I believe is done on purpose to ensure a continued supply. If you nee to dissolve more quickly them maybe crushing the pellets will help but I cant bet certain.
I have a 3 foot pecan tree I just transplanted to a 50 gallon pot. What is the best method to apply the Zinc Sulfate? Sprinkle on the dirt or dissolve and spray?
K. C. B on Apr 17, 2019
BEST ANSWER: Please do not use this product on potted trees, and you may want to seriously consider growing a pecan tree in the ground; they are not really suited to container growing.
I have 2 60 year old pecan trees it is getting ready to rain, should I split the 1 bag I bought and go around each tree with half of the pellets. I have no sprayer. How close to the bottom of the trees should I get? Thank you.
DeLynn on Apr 22, 2017
BEST ANSWER: Just distribute the pellets around the trees at the applicable rate. Let mother nature take care of it over time. Try and sprinkly the pellets about 2 ft. away from the trunk, out to the dripline. I'm very envious of your wonderful old pecan trees!
My walnut tree is not producing any English walnuts? What could be the problem?
Ppusher on Sep 12, 2020
BEST ANSWER: Thank you for your question. First, do a soil test to check the pH (it should be between 5.5 - 6.5 for apple trees) and see which nutrients it might be missing. Then fertilize accordingly. Is the tree getting at least 6 hours of full sun? Are your trees compatible pollinators, or the same variety? If the latter, that's why you're not getting a crop. There are other reasons a tree might not be bearing fruit as you expect. This article details some basic fruit tree requirements for fruit production.

Tree Does not bloom, bloomed once 4 years ago ?
Jim H on Jul 6, 2020
BEST ANSWER: Hi, Yes, I was having the same problem - my apple trees quit blooming. I used this in the fall and Spring, and they started blooming again. I'm going to keep using it and treating the trees Fall and Spring. That said, it also means the soil is too acidic (my trees catch the fall out from a lot of Virginia Pines), so I am also laying down a lot of lime as well. But, the lime will take a couple years to really permeate down low into the soil.
Do you have the zinc sulfate in larger bags?
Sandy W on Mar 11, 2019
BEST ANSWER: Hi, Sandy. I'm sorry, this is the only size that's manufactured.
For the past 2 years my pecans have had black streaks in the kernels will zinc help?
Bobbi on Sep 8, 2017
BEST ANSWER: This will definitely help. Many growers have this particular issue with pecans. For best results, apply foliar spray in early spring, when leaves are tender. You can also sprinkle the recommended amount on the ground and let Mother Nature rain it in. Only use as needed, as instructed by product label, and do not overuse.
When is the best time to treat trees with zinc?

Zinc used for pecan tree
The granuals are diluted in water and place in a sprayer to spray my one and only pecan tree. I do this twice a year. During the winter months I sprinkle the zinc on the ground and water. Without the zinc my pecan crop do not fill the shell completely with meat. Zinc absorbs into the leaves and bark when I spray.

Tall Pecan trees
We planted our pecans 10 years ago. They are some of the tallest trees on the place. We've been getting pecans off them for the last 2 years. That's ahead of when they were supposed to produce. We've used the zinc sulfate nearly every year. We like the results.

Zinc helped old pecan tree to full bloom
My 10+ year pecan tree bloomed for the first time this year. I have not seen any nuts on it yet but they may be there. I applied the Zinc last year. The two 10+ year trees that I did not put zinc around did not bloom this year. I may try Zinc on the others next year to get cross pollination. It is an effective product.
