Troubleshooting
Drooping Spleenwort problems — and how to fix them
Drooping Spleenwort (Asplenium flaccidum) 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 from overwatering
The most common cause of decline. Because of its epiphytic nature, the roots need air as much as moisture. Ensure the pot has excellent drainage, use a very open mix, and allow the medium to partially dry before re-watering. Remove rotted roots and repot into fresh mix if detected.
Frond tip burn
Brown, desiccated frond tips result from low humidity, fluoride toxicity in tap water, or fertiliser salt build-up. Switch to filtered or rainwater, flush the pot monthly, and increase humidity. Trim affected tips cleanly with sterile scissors.
Sluggish growth in winter
Growth slows markedly in cool, low-light winter conditions. This is natural. Reduce watering frequency and stop feeding until spring. Providing supplemental grow lighting in winter can maintain moderate growth through the season.
