Zanzibar Croton problems — and how to fix them
Zanzibar Croton (Codiaeum variegatum 'Zanzibar') 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 drop
Caused by relocation, cold drafts, low temperatures, or letting the soil dry out. The narrow leaves are especially quick to shed, so keep conditions stable.
Pale, green-yellow colouring
Insufficient light prevents the red and burgundy tones from developing. Provide brighter light with some direct sun.
Spider mites
The fine foliage and dry air invite mites. Raise humidity, rinse the leaves, and apply insecticidal soap or neem if infested.
Brown leaf tips
Low humidity or inconsistent watering. Increase humidity and keep the soil evenly lightly moist.
