Troubleshooting
Cercestis Mirabilis problems — and how to fix them
Cercestis Mirabilis (Cercestis mirabilis) 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.
Loss of silver variegation
Largely natural, as the bold juvenile pattern fades on mature leaves. Strong patterning is best kept by maintaining bright indirect light and healthy, steady growth on younger foliage.
Brown crispy edges and dull leaves
Low humidity is the usual culprit for this rainforest aroid. Raise humidity to 70% or more and keep the mix evenly moist to protect the velvet texture.
Leaf collapse from drying out
It does not tolerate a fully dry rootball. Water before the mix dries past the top couple of centimetres and never let it go bone dry.
Root rot in cold, wet soil
Combined cold and overwatering quickly rots the roots. Keep it warm above 20°C, use an airy mix and ensure the pot drains freely.
