Troubleshooting
Petra Croton problems — and how to fix them
Petra Croton (Codiaeum variegatum 'Petra') 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.
Sudden leaf drop
Crotons drop leaves when stressed by relocation, drafts, cold, or letting the soil dry out. Keep conditions stable and moisture even, especially after bringing a new plant home.
Green, dull new leaves
Too little light suppresses the red and orange pigments. Move to a brighter spot with some direct sun for vivid colour.
Spider mites
Dry air invites fine webbing and stippled leaves. Raise humidity, rinse the foliage, and treat with insecticidal soap or neem if needed.
Brown leaf edges
Low humidity or inconsistent watering. Increase humidity and keep the soil lightly and evenly moist.
