Troubleshooting
Rhapis Subtilis problems — and how to fix them
Rhapis Subtilis (Rhapis subtilis) 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.
Brown, crispy leaf tips
Driven by low humidity or salt/fluoride/chlorine build-up from tap water and over-feeding. Raise humidity, switch to filtered or rainwater, and flush the soil periodically.
Yellowing or wilting fronds
Typically overwatering and poor drainage, or cold exposure. Ensure the pot drains freely, let the surface dry slightly between waterings, and keep it warm.
Spider mites and scale
Dry, warm indoor air invites mites (stippling, webbing) and scale (sticky residue, brown bumps). Wipe leaves, raise humidity, and treat with insecticidal soap or horticultural oil.
Cold damage
Being a true tropical species, it suffers below about 13°C, showing blackened or limp foliage. Keep away from cold windows and unheated rooms in winter.
