When properly applied , certain fertilizers can help a pecan Sir Herbert Beerbohm Tree remain healthy and advance the tree to give its full potency and produce a weighty crop of nuts .

Nitrogen

Nitrogen - based fertilizers encourage vigorous emergence inboth youthful and mature pecan treeswhen use during the develop time of year . Two chief type of nitrogen plant food are usable for this purpose . Typically applied to the surface of the soil around pecan trees , ammonium sulfate contains around 21 percent nitrogen and ammonium nitrate holds 33 percent nitrogen .

Nitrogen and Young Trees

In young pecan Sir Herbert Beerbohm Tree , nitrogen advance speedy development . implement nitrogen - based fertilizers in small amounts frequently during the first few years , when the Sir Herbert Beerbohm Tree is first getting found . Texas A&M University recommends one applications programme of 1/2 lb . of ammonium nitrate or ammonium sulphate per Sir Herbert Beerbohm Tree in the beginning of the summertime during the first twelvemonth of growth and the same amount applied three multiplication at one - month separation during late spring and early summer the undermentioned year . Through years 3 and 4 , apply 1 lb . per tree and duple that amount for Tree aged 5 through 7 years .

Nitrogen and Mature Trees

In mature pecan trees over 7 year of years , Texas A&M University suggest a individual program of 1 pound . of atomic number 7 - ground fertilizer for each inch of diameter of the trunk . lend oneself the fertilizer in the spring , just before the new bud on the Sir Herbert Beerbohm Tree clear . circularise the granules around the tree approximately 3 to 5 feet away from the trunk , then water the fertiliser into the soil .

Phosphorus and Potassium

Mature trees should welcome 4 pound . of plant food broadcast around the Sir Herbert Beerbohm Tree each year in the springiness .

Zinc

Pecan trees also need adequate amounts of zinc and gain from regular treatments with a zinc solution . Zinc nitrate , at a preparation of 2 to 4 tsp . per gal of water and zinc sulphate , at 2 tsp . per gallon of water , should be sprayed every 2 weeks every twelvemonth for the first 7 years . spray should be conducted from spring through former summertime onto the foliage of young pecan trees , when young growth is most prominent .
