Troubleshooting
Brown Spiderwort problems — and how to fix them
Brown Spiderwort (Siderasis fuscata) 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.
Leaf rot from wet foliage
Never mist or water from above; the dense hairs trap moisture against the leaf surface and cause rot patches.
Brown leaf edges from low humidity
Increase humidity with a terrarium setup, pebble tray, or humidifier. This is a demanding plant for dry indoor environments.
Root rot from overwatering
Allow the top soil to dry between waterings. Use a well-draining mix and pot with drainage holes.
Leggy growth
Unusual for this rosette species but can occur in very low light. Move to brighter indirect light to maintain its compact form.
Mealybugs in leaf axils
Check the centres of the rosette regularly. Treat with isopropyl alcohol on a cotton swab as a first response.
