Buying Guide
What is a systemic drench for trees?
A systemic drench is a soil-applied insecticide that moves from the root zone through the plant’s vascular system, providing protection to foliage and new growth over a defined period. It is typically used to defend against sucking insects and certain pests that feed on sap.
Which product type fits my tree size?
Large trees often require higher-volume drenches (1 gallon or more) to ensure thorough root uptake, while smaller yards or shrubs can use half-gallon or 16-ounce formulations. Always follow label directions for dilution and application.
What trees and pests are commonly targeted?
Common targets include aphids, psyllids, borers, and other sap-sucking insects. Species suitability varies by product; check the label to confirm compatibility with your tree or shrub species.
How long does protection last?
Many systemic drenches claim protection up to 12 months under proper conditions. Environmental factors such as soil type, irrigation, and plant health can influence effectiveness and duration.
Storage, handling, and safety considerations
Store in a cool, dry place away from children and pets. Apply with appropriate protective gear and follow all label instructions for mixing, application, and disposal. Never exceed recommended rates or timing.
