Cape Cycad problems — and how to fix them
Cape Cycad (Stangeria eriopus) 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.
Tuber rot from overwatering
The underground stem rots quickly in wet, heavy soil, especially in winter. Use an open mix and let the surface dry before rewatering.
Scorched fronds
The soft, thin fronds burn in direct midday sun far more readily than stiff cycad leaves. Move to filtered light if leaf edges brown and crisp.
Scale and mealybugs
Sap-sucking pests gather along the frond midribs and crown. Remove by hand and treat with horticultural oil.
Slow or absent new flush
Like all cycads it flushes infrequently. Too little light, cold roots or an overcrowded pot will delay or prevent new fronds.
