Hi. I have 8 young avocado trees, and on the 2 Hass (on Zutano) ones there is a small area on a branch that has white growth on it. Under that is a brown discolouration with evenly spaced dots in the bark. I’d love to know what this is and what to do about it.
thanks

Hi Jill,
It sounds like a few of your avocados have a fungus problem.
You can cut the infected branches out if it is not affecting too much of the tree. Spray the whole tree with a liquid copper to control the fungal infection.
Things to check and adjust:
- Make sure the soil is free-draining.
- Adding compost and mulching improves the soil.
- Fertilise regularly so the plant in getting what it needs.
- Try not to overhead water and instead water at the base as overhead watering spreads fungal diseases.
- Keep the area free of damaged or diseased branches.
