Swertia-leaf Scaphosepalum problems — and how to fix them
Swertia-leaf Scaphosepalum (Scaphosepalum swertiifolium) 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.
Heat collapse
Sustained warmth above 22°C causes rapid decline. Prioritise the coolest microclimate in the home, especially in summer.
Stem and crown rot
Stagnant moist air causes fungal rot. Maintain continuous gentle airflow with a small fan.
Compacted medium
Sphagnum breaks down over time, reducing drainage. Repot annually into fresh fine sphagnum.
Mealybugs
White woolly deposits between leaves. Remove with alcohol-tipped swabs and treat with diluted neem oil.
Bud abort
Sudden temperature or humidity fluctuation causes buds to drop. Stabilise the growing environment.
