According to the Coretect product label: For best results on established ornamentals, CoreTect Tree and Shrub Tablets Insecticide should be placed as close to the fine absorptive roots as possible. For most deciduous trees and shrubs, an adequate number of these absorptive roots are located with 6-24” of the trunk, depending on tree size. Apply CoreTect Tree and Shrub Tablets Insecticide 2-5” below the soil surface, next to the plant (ca. within 3-5” of newly planted trees or shrubs, or within 6-24” of well-established ornamentals). Ensure that the tablets are completely covered with soil after application.
For bushy coniferous trees and shrubs, numerous absorptive roots may be located near the drip-line.

Ensure that the tablets are completely covered with soil after application.
