Can I save a willow with root rot?

If you catch it early by improving drainage and reducing water, the tree can recover. If the roots are black and mushy, the prognosis is poor.

How often should I water my willow?

Water every 3 to 7 days depending on the weather. Keep the soil consistently moist but never swampy.

White willow: root rot, causes and fixes

Check these first

Check the soil moisture at a depth of 3 inches.
Inspect the base of the trunk for soft or mushy bark.
Observe if water pools around the tree after rain.

Likely causes

Overwatering
Most likely
How to tell: The leaves turn yellow or brown and the soil feels constantly soggy to the touch. You might also notice a sour smell coming from the base of the tree.
What to do: Stop watering immediately and let the top 3 inches of soil dry out. If the tree is in a container, ensure the drainage holes are not blocked and consider repotting into a well draining mix.
Poor Drainage
Possible
How to tell: Water pools around the base of the tree for hours after rain or irrigation. The soil remains heavy and dense, preventing oxygen from reaching the roots.
What to do: Amend the surrounding soil with organic matter like compost to improve aeration. If the tree is in a low spot, build a small mound or berm to help water drain away from the trunk.

When to worry

If the entire canopy is wilting or the bark at the base is peeling away, the damage may be too severe to reverse. It is normal for a few lower leaves to drop during a heavy storm.

Stopping it coming back

Ensure your willow is planted in a spot that drains well and avoid watering if the soil is still damp.
