How to Keep Your Trees Healthy When There's No Rain

California summers get really hot and dry. When there’s no rain for weeks or months, your trees can get sick. You might not see it right away, but they’re working hard just to stay alive.

Don’t worry though. There are easy things you can do to help your trees make it through tough times. Let’s talk about how to keep them strong when the weather gets rough.

What Does a Thirsty Tree Look Like?

You need to know when your tree needs help. Here’s what to watch for:

Leaves turn yellow or brown
Leaves curl up or look burned
Leaves fall off too early (not in fall)
The tree grows slower than normal
You see cracks in the bark
Branches look dead or break easily

When you see these signs, your tree is telling you it needs water.

The Best Time to Give Trees Water

Water costs money and might be limited during dry times. You want to use it the smart way.

Water your trees early in the morning or after the sun goes down. This way, less water disappears into the air.
Give trees water slowly so it soaks deep into the ground. This helps the water reach the roots where trees need it most.
Try using a soaker hose or drip system. These work better than sprinklers because they put water right where you want it.
Water the area under the tree's branches, not just next to the trunk. The roots spread out under the whole tree.

Big, old trees still need water during dry times. They just don’t need it as often as young trees. Water them every two to four weeks based on how hot it gets.

Mulch Helps Trees Stay Cool and Wet

Mulch is like a protective blanket for your tree’s roots. It’s one of the best things you can do.

Mulch does three great things:

Don't Feed Trees During Dry Times

When trees are stressed, they need rest, not food. Put away the fertilizer until it rains again.

Fertilizer makes trees grow new leaves and branches. New growth needs lots of water that your tree doesn’t have.

Fertilizer can also hurt stressed roots. This makes things worse for your tree.

Wait for normal rainfall before you start feeding your trees again. Right now, your tree just wants to survive.

Pick Your Most Important Trees

Maybe you can’t water every tree in your yard. That’s okay. Focus on the ones that matter most.

Young trees under 5 years old need the most help. Their roots are small and can’t reach water deep in the ground.

Save your big shade trees and trees that belong in California naturally. These are worth the extra effort.

Let your grass, bushes, and other plants rest if you need to. They’ll come back when it rains.

Use your water where it will do the most good.

Don't Cut Too Much Off Your Trees

You might think cutting branches will help your tree during dry times. Actually, it can hurt more than it helps.

Don’t do heavy pruning right now. This puts extra stress on your tree when it’s already struggling.

Only cut off branches that are dead, broken, or might fall and hurt someone.

Save big trimming jobs for when it’s cooler and wetter outside.

Let your tree keep its leaves. They make shade for the roots and help save water.

Think About the Future

Planning to plant new trees? Pick ones that can handle dry weather.

Trees that grow naturally in California usually need less water. Good choices include Coast Live Oak, Palo Verde, and California Sycamore.

Stay away from trees that drink lots of water, like willows.
