Organic Pecan And Fruit Tree Program



Pecan trees and most other fruit trees can be grown organically with great success. Pecan trees and other fruit trees should never have bare soil in the root zone, but should always be covered with native shredded mulches and/or native grasses and legumes. Trees should be planted high with natural organic techniques. Trunk flares should be easily visible. Exposing the flares properly is the most important first step.


Round #1 February: Mechanically aerate root zone and apply organic fertilizer @ 20 lbs. per 1,000 square feet, whole ground cornmeal at 20 lbs. per 1,000 square feet, dry molasses @ 20 lbs. per 1,000 square feet and lava sand at 80 lbs. per 1,000 square feet.

Round #2 June: Organic fertilizer @ 10 lbs. per 1,000 sq. ft. and greensand @ 40 lbs. per 1,000 sq. ft. Use soft rock phosphate or other rock mineral such as Asomite at 40 lbs. per 1000 square feet.

Round #3 September: Organic fertilizer @ 10 lbs. per 1,000 sq. ft. and sul-po-mag @ 20 lbs. per 1,000 sq. ft. Clean wood charcoal can also be used. See Terra Petra on


1st spraying: Spray Garrett Juice and cornmeal tea at pink bud. Also drench it throughout the root system at 1 gal. per 1000 sq ft.

2nd spraying: Use the same mix after flowers have fallen.

3rd spraying: About June 15th (later in northern locations)

4th spraying: Last week in August through mid September. Use additional sprayings as time and budget allow.

Note: If other quality organic sprays are used, make sure apple cider vinegar is included at one ounce per gallon.


ALTERNATE PROGRAM (After first year or for limited budget projects)

1) Apply dry molasses or sorghum at 20 lbs. per 1000 square feet.

2) Spray Garrett Juice and cornmeal tea every 30 days.


Very little pruning is needed or recommended. Maintain cover crops and/or natural mulch under the trees year round. Never cultivate the soil under pecan and fruit trees.


Trichogramma wasps: Weekly releases of 10,000 - 20,000 eggs per acre or residential lot starting at bud break for 3 weeks

Green lacewings: Release at 4,000 eggs per acre or residential lot weekly for one month

Ladybugs: Optional and as needed - release 1,500 - 2,000 adult beetles per 1,000 square feet when shiny honeydew is on foliage.


Fruit trees and ornamental flowering trees will benefit from the organic program.
