Troubleshooting
Cas Guava problems — and how to fix them
Cas Guava (Eugenia victoriana) 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.
Fruit fly infestation
Caribbean fruit fly and related species attack ripening fruits. Use protein bait traps and remove fallen fruit promptly. Exclusion netting over developing fruit clusters is highly effective in home gardens.
Root rot from waterlogging
Poorly drained soils cause Phytophthora root rot, leading to sudden wilting and yellowing. Ensure raised beds or containers drain freely; avoid irrigation immediately after heavy rain.
Sparse fruiting
Insufficient sunlight or irregular watering during bud initiation are the most common causes. Ensure full sun placement and consistent soil moisture; cross-pollination from a second plant can improve fruit set.
