Deep Watering

Davey’s Deep Watering Program Can Help Protect Your Valuable Trees and Shrubs

Your landscape represents a huge investment, and with proper care, all of your trees and shrubs can thrive and continue to provide you and your family with years of enjoyment. Taking care of your trees requires an understanding of water management. This is something that requires both time and attention to help reduce risks and to better help your trees survive during the drought.

Davey’s deep watering program is designed to improve soil moisture around your trees and shrubs. Trees and shrubs need water to grow and to stay healthy. But how much water do they need and how often? There are several factors that determine this:

Deep Watering1. Species – some plants are native to naturally wetter or dryer climates, while other plants are native to warmer or colder climates. For example, coast redwood trees are native to cooler climates that receive three times the amount of water they receive in the Santa Clara Valley.

2. Deciduous or evergreen – Deciduous trees lose their leaves in the fall, and they become dormant through winter. Therefore, they require less water than evergreens.

3. Compatibility of species – Ivy growing near trees is in direct competition with trees for water. Juniper shrubs (low water requirement) near Monterey pines (high water requirement) is another example of incompatibility.

4. Efficiency of the irrigation system – Spray heads will deliver too much water in too short a period of time, leading to either evaporation or runoff. Is the drip irrigation system on long enough to adequately deep water the trees and shrubs?

5. Time of the year – Research has shown that the longer daylight hours, combined with high temperature and wind, greatly increase the amount of water used by trees and shrubs. This is particularly true during the months of May through September.

6. Soil density - A compact soil (high density) is a barrier to water penetration. Also, soil amendments or soil fill, on top of the native soil, can create a barrier to water penetration.

How does Davey effectively water your trees and shrubs? By using a special probe and high pressure, we can inject water directly into the root zones of trees and shrubs. This allows them to maximize the use of the water and lessens the risk of evaporation or runoff. And, because we bring the water with us, we do not have to use yours. Our arborists can evaluate how much water your trees and shrubs need and how often they need to be watered, and provide a watering program for you. They can help you prioritize by species if desired.
