Subsurface Watering

Water Your Trees Where It Counts

Subsurface watering improves tree health in drought-prone areas or during times of extreme heat or dry soil conditions.

It’s specifically designed to improve soil moisture around your trees and shrubs by an injection probe that distributes water directly into the root zone, hydrating drought-stressed trees.

By placing water below grade, it is more efficiently distributed and less likely to run off or evaporate. This soil injection technique allows water to bypass slow infiltration rates in soils that contain high clay content, making it a viable alternative to surface watering.

Helping Trees in an Unexpected Heat Wave

As the summer heat intensifies, trees may struggle to cope, showing signs like wilting, leaf scorch, and stunted growth. Recognizing these symptoms promptly is crucial. Deep, infrequent watering, allowing the soil to drain between watering sessions, is key. Young trees require extra hydration for establishment, typically 5 to 15 gallons weekly.

Apply water directly to the soil, avoiding evaporation, and replenish mulch to shield roots from heat. Regularly check irrigation systems to ensure proper water distribution, preventing over or under-watering.

Protect your trees from the adverse effects of heat waves by taking proactive measures to maintain their health and vitality.

Signs Of Drought Stress In Trees

Signs of drought (or heat stress) will be the most visible in the foliage. Look for these common symptoms:

Leaf wilt or leaves that start to curl
Scorched, gray-tinted leaves
Leaf loss
Thinning canopy
Branches drying out and dying
Wood-boring insects
Pine tree discoloration: Pines turn grayish-green color and then turn into rust once dead

What not to do during a drought:

Water on windy or rainy days
Over-water
Adjust sprinklers to aim at the trunk of trees, which may cause trunk cankers or lead to root-rot diseases

How To Help Your Trees Survive Dry Conditions

Trees recovering from a harsh winter, temporarily coping with heat stress, or lacking a seasonal substitute for an irrigation system, can benefit from subsurface watering.

Consider subsurface watering for:

Trees and shrubs without irrigation systems
Newly planted trees
Temporary relief of heat stress, especially on large, mature trees
Evergreen trees at risk from winter drying conditions
