Hi-Yield® Zinc Sulfate

Zinc deficiency is one of the most common and damaging nutrient disorders affecting pecan trees — and Hi-Yield® Zinc Sulfate is the straightforward solution. Low soil zinc levels cause Rosette, a serious disorder that stunts tree growth, deforms nuts, and reduces productivity significantly if left uncorrected. Apply as a fast-acting foliar spray in early spring for rapid correction, or as a soil additive for longer-term zinc supplementation. An essential tool for any pecan grower.

What Is Rosette and Why Zinc Matters

Rosette is a zinc deficiency disorder specific to pecan trees — characterized by stunted, abnormal leaf development, reduced growth, and malformed nuts that lower crop quality and yield. It’s most common in areas where soil zinc levels are naturally low or where heavy cropping has depleted available zinc over time. Correcting zinc deficiency with a targeted zinc sulfate application is the most direct and effective way to address the problem and restore healthy, productive growth.

Two Ways to Apply — Foliar Spray or Soil Additive

Hi-Yield® Zinc Sulfate gives you flexibility in how you apply it:

For foliar spray (fast-acting): Mix 1 tablespoon per 3 gallons of water and apply when leaves are tender in early spring. Foliar application delivers zinc directly to the leaves for rapid uptake and correction.

For soil additive (longer-term): Apply 1¾ lbs. per inch of trunk diameter to build soil zinc levels over time. Use only as needed and do not overuse — follow product label instructions carefully.
