Troubleshooting
Surinam Cherry problems — and how to fix them
Surinam Cherry (Eugenia uniflora) 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.
Invasive self-seeding
Birds spread the seeds, and the plant has become invasive in parts of Florida, Hawaii and other warm regions. Remove unwanted seedlings and avoid planting where it can naturalise into wild areas.
Caribbean fruit fly and other fruit pests
The soft fruit is attractive to fruit flies, which lay eggs in ripening fruit. Harvest promptly, clear fallen fruit, and bag or net crops where fruit-fly pressure is high.
Resinous, sour fruit if picked early
Under-ripe fruit is acidic and turpentine-like. Let fruit fully colour to deep red or black and soften before picking for the sweetest flavour; chilling cut fruit can mellow resinous notes.
Scale and leaf spot
Scale insects and, in humid conditions, fungal leaf spot can affect plants. Treat scale with horticultural oil and improve airflow by thinning crowded growth.
