Feed during active growth. The described options are a monthly houseplant application or one or two feeds in the growing season. No trigger for increasing frequency is established.
When to feed Codiaeum variegatum
Feed a croton while it is actively growing. One documented option is a half-strength monthly soluble feed. Another is one or two feeds across the growing season, not a year-round routine.

Check for active growth
When to fertilize
Reduce or stop routine feeding as fall and winter light and growth decline. A very bright, actively growing indoor croton may not follow the same winter pattern, but no supplemental-light schedule or restart threshold is established.
Follow the product label
Fertilizer type and dose
Use an all-purpose soluble or general liquid houseplant fertilizer. No brand, organic formulation or universal nutrient ratio is established for every Codiaeum cultivar.
A half-strength croton option is available. For another product, follow its label. No single milliliter dose fits every product or container.
