Zinc Sulfate

Zinc is one of eight micro nutrients plants depend upon for proper health. This micro nutrient is essential for plant growth and development.  Zinc Sulfate helps deliver needed zinc into soil or plants during the growing season.  A good resource for organic gardeners that can help boost your vegetable production and keep your plants is zinc sulfate.

Zinc Sulfate for Pecan Trees

Zinc is an essential nutrient for pecan trees. It plays a role in the development of new leaves and flowers, as well as in the growth and production of nuts. Pecan trees that are deficient in zinc will not produce as many nuts as those that are properly fertilized with zinc.  We discuss how much zinc sulfate for pecan trees and the application rate below.

Zinc Sulfate for Gardens

One of the most disheartening obstacles are areas where the topsoil was removed during construction. Even with the addition of generous amounts of compost, the soil often lacks micronutrients such as zinc. The symptoms of insufficient zinc are similar to those of iron deficiency: stunted plants with small, yellowed and deformed leaves.

Prilled Zinc Sulfate

Our Zinc Sulfate is not powder but an easy to work with granulation called mini prill.  You could fit 3 or 4 of these mini prill balls into a BB size.  We package our zinc sulfate in factory sealed thick plastic bags.  This helps protect the product from outside elements and moisture.

How Much Zinc Sulfate For Pecan Trees?

Pecan trees use lots of zinc. It is an essential nutrient for strong growth and heavier nut production. Mostly, zinc sulfate applied to pecan trees as a foliar spray. When applying this way, the trees can absorb the zinc right away. Young trees and vegetating trees need applications of zinc on new growth during the spring starting at budbreak and continuing for three sprays at 2- to 3-week intervals.  So, how much zinc sulfate pecan trees you ask?  Zinc sulfate is the primary source of zinc used by pecan farmers and should be mixed at 2 to 3 pounds per 100 gallons of water.

Soil applications of zinc sulfate are far less effective than foliar applications and are only useful when the soil pH is below 6.0. If soil pH is below 6.0, then a 1/2 pound of zinc sulfate per year of age of the tree can be soil-applied under the tree up to 10 pounds of applied zinc per tree total.  Be sure to apply around the canopy of the tree and NEVER near the trunk of the tree. Even so, a foliar application is more effective and is the preferred application method.

Why Use Zinc Sulfate For Pecan Trees?

Zinc is one of the most essential nutrients for pecan trees. It plays a critical role in the growth of new leaves and flowers, as well as in the growth and heaviness of nuts. Pecan trees that are zinc deficient will not produce as many heavy nuts, as well as a sparse yield in general, as those that are properly fertilized with zinc.

If pecan trees are planted in zinc deficient soil, you can guarantee that your pecan tree will show signs of being short of zinc.  Zinc deficiency can cause the leaves of the tree to wave or curl, or have long branches with only a clump of leaves.  Along with those symptoms you will find more common symptoms like yellowing of leaves and very slow growth.  For more information on tree health from a tree service please visit our friends at
