Troubleshooting
Sarpagandha problems — and how to fix them
Sarpagandha (Rauvolfia serpentina) 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.
Root rot
Overwatered or poorly draining soil causes root rot. Ensure containers have drainage holes and allow the top few centimetres to dry before rewatering. Affected plants show wilting despite moist soil; remove rotted roots and repot in fresh mix.
Leaf yellowing
Yellow leaves commonly result from alkaline soil, nitrogen deficiency, or excessive direct sun. Test soil pH and amend to 6.0–6.8 with sulfur or acidifying fertiliser. Shift the plant to brighter indirect light if yellowing accompanies leggy growth.
Scale insects
Waxy brown scale can colonise stems, especially under low humidity. Wipe affected areas with a cotton swab dipped in isopropyl alcohol, or apply horticultural oil spray. Improve air circulation and avoid overcrowding to discourage reinfestation.
Prevent sarpagandha problems before they start
Most sarpagandha issues are care-mismatch, not bad luck. Dial in the basics:
