Arching Spider Orchid problems — and how to fix them
Arching Spider Orchid (Brassia arcuigera) 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.
Bud blast (buds yellowing and dropping)
Triggered by dry air, low humidity, or sudden temperature swings while spikes develop. Hold humidity high and conditions stable once buds form.
Soft, rotting roots
Overwatering or a stale mix in a plant that wants air at its roots. Switch to a coarser medium, water on a dry-down cycle, and ensure rapid drainage.
Sunburn patches on leaves
Bleached or scorched spots from direct sun. Move to brighter but filtered light rather than unshaded glass.
Spider mites in dry air
Fine stippling and webbing on the undersides of leaves. Raise humidity and treat promptly with insecticidal soap or horticultural oil.
