Aerangis rhodosticta problems — and how to fix them
Aerangis rhodosticta (Aerangis rhodosticta) 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.
Black or sunken leaf spots
Fungal or bacterial infection from water sitting on foliage overnight. Water early in the day, improve airflow, and remove affected tissue with a sterile blade.
Shrivelled, dehydrated leaves
Usually root loss from drying out (mounts dry fast) or, conversely, rot from stagnant moisture. Check root health and adjust watering frequency to the mount-versus-pot setup.
Bud blast before flowers open
Triggered by humidity crashes, sudden temperature swings, or dry air. Keep humidity above 65 percent and conditions stable through the budding period.
White crusty salt deposits on roots and mount
From hard tap water or over-fertilising. Switch to rain or RO water and flush regularly with plain water.
