Tree & Shrub Program

For many years, Greenleaf has monitored population surges of the major pests proven to be most damaging to ornamentals in South Louisiana and actively managed regional landscape problems. The Greenleaf program for landscape ornamentals is the end product of years of this “hands-on” experience. Outlined below is the schedule of treatments we recommend to maximize the health and vigor of your landscape. This is a maintenance spray program for trees and shrubs. While we cannot prevent disease and insects from invading your landscape, we can eliminate the issues at first sight.

Our program includes six applications per year (approximately 6–8 weeks apart, depending on weather). Our chemical mixes may vary, depending on specific landscape needs.

Round 1: Deep root fertilization of trees
1 Early Spring Fertilization:
(January–March)		 Applying a complete analysis liquid formulation, we fertilize your trees with a “deep-root soil injection” technique.
Rounds 2–6: Insect and disease prevention with liquid fertilizer
2 Spring Insect/
Disease Treatment
(April–May)		 Many species of insects and mites survive throughout the winter. This treatment is designed to initiate control of leaf feeding caterpillars, and over wintering adults.
3 Early Summer Insect/
Disease Treatment
(June–July)		 Combining the latest in landscape pest management materials, this treatment is directed at insects, mites and diseases common to this season such as aphids, spider mites, leaf blights, lace bugs, etc.
4 Late Summer Insect/
Disease Treatment
(September–November)		 Our high-temperature, high-rainfall and high-humidity environment requires that we stay one step ahead of damaging landscape pests such as powdery mildew, spider mites, hawthorne leaf spot, scale insects, aphids, and sooty mold.
5 Late Summer Insect/
Disease Treatment
(September–November)		 Continued high temperatures and high humidity offer the perfect conditions for egg-laying insects, caterpillars, and leaf blights such as web worms, spider mites, aphids, leaf feeding beetles, etc.
6 Fall Insect/
Disease Treatment
(November–December)		 With the onset of the cooler season, we are offered the opportunity to use Oil-A-Cide formulations to smother many hard-to-control species such as scale insects, pupae and egg stages of insects and mites, etc.
