Drought Care for Trees

As the drought continues, our urban forest is in need of extra care. Here are some simple ways to care for your trees while saving water.

Know Your Watering Rules

Each city and county has different rules for outdoor watering. Be sure you know which days of the week you can water your trees.

Add Mulch Around Your Trees

Wood chip mulch is one of the best ways to save water and can keep your trees healthy. A thick layer of mulch will keep moisture in the soil and protect the roots from extreme heat, so you use less water and your trees stay happy!

Check the Soil

Some trees will need to be watered more often than others. How do you know if it's time to water your tree? Check the soil!

Use a small shovel or screw driver to check the soil 6-8 inches below the surface.

If the soil feels dry and crumbly, it's time to water your tree with a slow soak. If the soil feels sticky or wet, let it dry for a couple days before checking it again.

Water Responsibly With a Slow Soak

You want water to reach the roots of your tree, so water needs to slowly soak into the soil to reach the roots 12-18 inches below the surface. Because roots extend as a tree grows, young trees and mature trees need different watering techniques. 

Watering Young Trees 

You can conserve water and keep your young tree healthy! Just remember, 1-2-3 Water Your Tree!

 

1. Collect water in a bucket while your shower warms up.

2. Drill a small hole (1/8") near the bottom of a second bucket and place it near the trunk of your young tree.

3. Fill second bucket with the shower water you saved.

The water will slowly drip into the soil and keep your tree happy and healthy! 

Your young tree only needs 10-15 gallons of water per week. That's the same amount of water used in a 6 minute shower!

Watering Mature Trees 

The roots of a mature tree extend underground even wider than the branches extend above ground. Use a soaker hose spiraled under the drip line of your tree (the soil beneath the edge of the leaves) or an oscillating sprinkler on a low setting to slowly soak as much of the root zone as possible. Allow the water to slowly drip into the soil for several hours. 

 

These methods prevent unnecessary water runoff and provide the necessary water directly to the tree's roots.

*Native oak trees which have never received regular irrigation do not need this type of watering. If you have questions about your large, native oaks or concern about the health of your tree, contact a Certified Arborist.
