Croton (Codiaeum variegatum) care

Other · needs attention to keep

Croton (Codiaeum variegatum) wants bright light with a few hours of direct sun. Water it every 6 days. Keep evenly damp. A croton that dries out drops every leaf, often overnight, and takes months to recover. Pot it in rich, free-draining compost. A balanced feed at half strength every two weeks in spring and summer, and repot every 1.5 years. Humidity: above 60%. Toxic to cats and dogs — the milky sap irritates the mouth and causes vomiting, and it can irritate skin on contact.

Croton: leathery leaves splashed in yellow, orange, red and green, in leaf shapes ranging from oak to corkscrew. The colour is made by light, so a croton in a dim spot slowly turns green and stops being worth having. It also drops every leaf when it is moved or allowed to dry — expect a sulk after you bring it home.

Watering a Croton

Water every 6 days. Keep evenly damp. A croton that dries out drops every leaf, often overnight, and takes months to recover.

That cadence is the one PlantParlour sets for this species when you name it, and it is deliberately on the cautious side — a plant that asks a day early is safer than one that asks a day late. Log each watering and the reminder moves with the plant rather than with the calendar.

Light

Bright light with some direct sun. The colour in a croton is made by light — in a dim spot the new leaves come out plain green and the plant stops being the thing you bought.

Humidity and temperature

Above 60%. Central heating in winter is what turns a comfortable room into a dry one, and it is the usual reason an established plant suddenly browns at the edges or picks up spider mites.

Soil and potting

A rich compost with perlite. Crotons want moisture and food but not a waterlogged pot.

Feeding

A balanced feed at half strength every two weeks in spring and summer. Stop feeding in autumn and start again when you see new growth in spring — feeding a plant that isn't growing just builds up salts in the pot.

Repotting

Repot every 1.5 years. Every second spring. Prune in spring if it goes bare below; it branches from the cut.

Common problems

All the leaves drop at once
A shock: a move, a draught, a cold delivery van, or drying out.

Fix: Keep it warm, bright, damp and still. New growth usually comes in a few weeks.
New leaves plain green
Not enough light.

Fix: Move it into the brightest spot you have.
Spider mites
Dry air. Crotons attract them badly.

Fix: Raise the humidity, shower it, and treat weekly for a month.

Propagation

Stem cuttings in spring, dipped in water to stop the sap, rooted under cover with bottom heat.

A cutting taken in PlantParlour keeps its link to the plant it came from, so a propagation years later still traces back to the mother plant — which is the point if you ever sell or trade it.

Toxicity and safety

Toxic to cats and dogs — the milky sap irritates the mouth and causes vomiting, and it can irritate skin on contact.

Named cultivars and variegations

Codiaeum variegatum is sold under several cultivar names. Care is the same unless noted; variegated forms carry less chlorophyll, so they grow more slowly and want more light than the plain species.

Cultivar	Also sold as	Water
'Petra'	Croton Petra	every 6 days
'Mammy'	Croton Mammy	every 6 days

Questions people ask

How often should you water a Croton?

Water every 6 days as a starting point — that is the cadence PlantParlour sets for Codiaeum variegatum. Keep evenly damp. A croton that dries out drops every leaf, often overnight, and takes months to recover. Light, pot size and the time of year all move that number, so treat it as a reminder to go and check rather than a rule.
