Troubleshooting
Red Ginger problems — and how to fix them
Red Ginger (Alpinia purpurata) 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.
Leaf tip burn
Brown or scorched leaf tips indicate low humidity, exposure to direct harsh sun, or fluoride sensitivity. Use low-fluoride water (rainwater or filtered), increase humidity, and move out of harsh midday sun.
Lack of flowering
Red ginger needs warmth above 21°C, high humidity, and established rhizomes (typically 2+ years) to bloom reliably. Congested clumps may reduce flowering — divide every 3–4 years to rejuvenate.
Spider mites in low humidity
Fine stippling on upper leaf surfaces and webbing underneath signals spider mites, common when air is too dry. Boost humidity, hose down foliage regularly, and treat with insecticidal soap or neem oil.
