Pointed-Cap Ginger problems — and how to fix them
Pointed-Cap Ginger (Alpinia oxymitra) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Spider mites in low humidity
The most likely pest problem when grown under glass in warm, dry conditions; silvery stippling on leaves and fine webbing on undersides are the tell-tale signs. Raise humidity, rinse leaves regularly with water, and apply insecticidal soap or neem oil if infestations develop.
Chilling injury
Exposure to temperatures below 15 °C (59 °F), particularly with cold draughts, causes leaves to yellow and collapse and may kill growing tips. Keep in a heated environment year-round and protect from any cold ventilation; recovery from severe chilling is slow.
