Troubleshooting
Rumberry problems — and how to fix them
Rumberry (Myrciaria floribunda) 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.
Scale insects
Common on container specimens; scrape off manually or treat with horticultural oil.
Slow establishment
Rumberry is notoriously slow-growing; patience and consistent moisture in the first 2 years are critical.
Iron chlorosis
Yellowing between leaf veins on alkaline soils; apply chelated iron and acidify if needed.
Fruit drop
Erratic watering or low temperatures during flowering cause premature fruit drop.
Root rot
Poorly drained containers are the main risk; always use free-draining mix and ensure drainage holes are clear.
