Croton care guide
Codiaeum variegatum
Also known as: Garden croton, Variegated croton
Pets and children
Considered toxic
The milky sap in leaves and stems is irritating: dogs and cats that chew it can vomit, get diarrhea or skin irritation, so keep it out of reach and contact a veterinarian (or a doctor, for a child) if eaten.
How often to water Croton
- Spring–Summer (Mar–Sep)
- Every 4 days
- Water thoroughly once the topsoil is dry, as a guide; in summer it dries quickly, so mist the leaves often too.
- Autumn (Oct–Nov)
- Every 7 days
- Once it cools, wait about a day or two after the topsoil dries before watering.
- Winter (Dec–Feb)
- Every 10 days
- Water sparingly about three to four days after the soil dries, during a mild part of the day.
Light and placement for Croton
A sunny spot all year is generally right; short of light the colors revert to green and lower leaves drop, and while an acclimated plant grows well in full sun outdoors, a sudden move into direct sun scorches it.
Overwintering Croton
Overwintering guide: 10°C (50°F) or above
Tender to cold: overwinter it in a warm room kept at about 10°C, away from cold windowpanes and direct heater draft, with sparing watering; sudden temperature swings make it drop leaves.
Fertilizing and repotting Croton
Fertilizer
From May to September, slow-release fertilizer about every two months or liquid feed about every two weeks; ease off from October and give none in winter.
When to repot
Spring–Summer (Mar–Sep)
Common problems with Croton
- Winter cold or a cold draft makes the leaves drop one after another from the bottom.
- Too little light drains the bright colors, leaving the leaves greenish.
- Spider mites in a dry room leave the leaves faded and they fall.
Tips for growing Croton
- When moving it, acclimate it over several days to reduce leaf drop.
- The white sap from cuts can irritate skin and stain clothes, so wear gloves when pruning.
- Frequent misting keeps the leaves glossy and discourages spider mites.
These are AI-generated general guidelines. They vary with the variety, the placement and the pot size. For effects on pets or children, consult a veterinarian or a doctor.
