Can I save a honey mesquite with root rot?

If caught early, you can save it by correcting the watering habits and improving drainage. If the roots are black and mushy, the tree may not recover.

How often should I water my honey mesquite?

Water every 14 to 30 days depending on the heat. Always water deeply to encourage deep roots rather than frequent shallow drinks.

Honey mesquite: root rot, causes and fixes

Check these first

Check the soil moisture at a depth of 6 inches.
Inspect the base of the trunk for soft or mushy bark.
Verify that your irrigation system is not leaking near the roots.

Likely causes

Overwatering
Most likely
How to tell: The foliage may wilt or yellow even when the ground feels wet. You might notice a sour smell coming from the soil.
What to do: Stop watering immediately and let the soil dry out completely. If the tree is in a container, ensure the drainage holes are not blocked. Only water again when the top 6 inches of soil are dry to the touch.
Poor Drainage
Possible
How to tell: Water pools around the base of the tree for hours after irrigation or rain. The soil feels heavy and dense like clay.
What to do: Amend the surrounding soil with coarse sand or gravel to improve aeration. If the tree is in a pot, repot it into a fast draining cactus mix. Avoid planting in low spots where water collects.

When to worry

If the leaves are dropping rapidly and the trunk feels soft, the damage may be severe. It is normal for a few older leaves to yellow and fall during the transition between seasons.

Stopping it coming back

Always follow a deep and infrequent watering schedule to mimic the natural desert cycle. Ensure your soil is well draining before planting.
