Zinc Makes Big Leaves
Beautiful pecan trees and regular harvests of high quality pecans begin each spring with frequent zinc sprays. Good foliage is the secret to optimum growth, healthy trees and regular production. Mature pecan trees can have double the amount of foliage with three or four zinc sprays in April and May. Leaves on mature trees are fully grown by June, so spray early and frequently. Young pecan trees can grow six feet instead of six inches in one year if zinc is sprayed onto the foliage every two to three weeks from April until August. This is, of course, in combination with a good management program.
