Troubleshooting
Fuerte Avocado problems — and how to fix them
Fuerte Avocado (Persea americana 'Fuerte') is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Phytophthora root rot
Main avocado killer, caused by waterlogging. Use very free-draining soil, water carefully and choose resistant rootstock; prevention is far easier than cure.
Poor fruit set
'Fuerte' is type-B and can be a shy bearer; warm, calm bloom weather and a type-A partner like 'Hass' nearby improve pollination.
Iron chlorosis
Yellowing between leaf veins on alkaline or wet soils. Improve drainage, lower pH slightly, and apply chelated iron.
Frost and cold damage
Hardy only to around -2 to -3°C; frost damages new growth and fruit. Protect or move under cover in cold weather.
