Can I save a tree with root rot?

If caught early, you can save it by correcting the drainage and letting the soil dry out. If the roots are already black and mushy, recovery is very difficult.

How often should I water to prevent this?

Water deeply every 7 to 14 days, but always check the soil first. If the top few inches are still moist, wait a few more days before adding water.

Check these first

Check the soil moisture at a depth of 3 inches.

Likely causes

Poor Drainage
Possible
How to tell: The leaves may yellow and drop prematurely even if the soil feels wet. You might notice a sour or swampy smell coming from the base of the tree.
What to do: Improve the soil drainage by amending the surrounding area with organic matter or sand. If the tree is in a container, repot it into a well draining mix and ensure the pot has large drainage holes.
Overwatering
Possible
How to tell: The foliage wilts and turns yellow despite the soil being constantly saturated. The roots will appear mushy and dark brown rather than firm and white.
What to do: Stop watering immediately and allow the top 3 to 4 inches of soil to dry out completely. Adjust your schedule to water only every 7 to 14 days depending on the weather.

When to worry

Root rot is a serious condition that can be fatal if the majority of the root system is affected. If the trunk base feels soft or spongy, the damage is likely too far gone.

Stopping it coming back

Always plant your tree in a spot with excellent drainage and avoid watering if the top few inches of soil are still damp.
