Croton Codiaeum variegatum

Reviewed June 2026 · how we check this

The garden croton is grown for its riotous, leathery foliage — leaves splashed and veined in green, gold, orange, red, and burgundy that deepen with strong light. Spectacular but a little particular: it craves bright light, steady warmth, and humidity, and protests any sudden change by dropping leaves.

Light

Croton needs the brightest spot you can give it — the color it's famous for is light-driven. An east window with morning sun, or a south/west window with 2–4 hours of direct sun, keeps the reds, oranges, and yellows vivid. In dim light the variegation fades back to plain green and the plant grows leggy and sparse. Acclimate it slowly to stronger sun over a couple of weeks to avoid bleached, scorched patches. If your croton's new leaves are coming in mostly green, it's telling you it wants noticeably more light.

Watering

Keep the soil evenly moist but never waterlogged — croton dislikes drying out fully as much as it hates sitting wet. Water when the top inch feels dry, soaking until it drains, then empty the saucer. In a warm, bright spot that's often every 5–7 days in spring and summer, stretching to 7–9 days or more in winter. Watch the leaves: sudden wilting and lower-leaf drop usually means it went too dry, while soft yellowing leaves with constantly damp soil point to overwatering. Lukewarm water is gentler than cold straight from the tap.

Soil & potting

Use a rich but fast-draining mix: a quality potting mix lightened with perlite or pumice, plus a handful of orchid bark or coco coir to hold a little moisture without going soggy. Croton likes some organic richness but its roots still need air, so avoid heavy, water-retentive soil. Always pot into a container with drainage holes. Repot every 1–2 years in spring when roots fill the pot, moving up a single size — an oversized pot stays wet too long and invites root rot.

Humidity & temperature

Croton is a humidity lover and shows it: dry indoor air brings brown, crispy leaf edges and spider mites. Aim for 50–60%+ with a humidifier, a pebble tray, or by grouping it with other plants. Keep it warm and steady at 60–85°F; it suffers below 55°F and a cold draft or a chilly window can trigger dramatic leaf drop. Keep it well away from heating vents, air conditioners, and doorways — croton hates sudden temperature swings more than almost anything.

Fertilizing

Feed with a balanced liquid houseplant fertilizer at half strength every 2–4 weeks through spring and summer, when croton is actively growing and coloring up. Pause feeding in fall and winter as growth slows, then resume in spring. Don't overdo it — excess fertilizer shows as brown, scorched leaf tips and a white crust on the soil surface. If that happens, flush the pot thoroughly with plain water to leach out the built-up salts.

Pruning & maintenance

Prune in spring to shape a leggy plant and encourage bushier growth — cut just above a leaf node with clean snips, and the plant will branch below the cut. Pinching back the growing tips on young plants keeps them full rather than tall and bare. Croton's sap is a milky latex that can irritate skin, so wear gloves and wash up afterward. Wipe the broad leaves occasionally with a damp cloth to keep them glossy and to spot mites early.

Propagation

Propagate from stem-tip cuttings in spring or summer. Take a 4–6 inch cutting with several leaves, blot or rinse the milky sap, dip the cut end in rooting hormone, and set it in moist, airy mix. Warmth and high humidity are essential — a clear cover or propagation box and bottom heat speed things along. Roots typically form in 4–8 weeks. Croton is notoriously stubborn to root, so start several cuttings to improve your odds.

Through the year

Spring

Growth resumes — restart regular feeding, repot if rootbound, prune leggy stems, and take cuttings while the plant is energized.

Summer

Peak growth and color. Keep the soil evenly moist, feed every couple of weeks, hold humidity high, and watch for spider mites in the heat.

Fall

Growth slows — ease off the water a little, stop fertilizing, and move it back from any window that turns cold.

Winter

Near-dormant and vulnerable to drop. Keep it warm and bright, run a humidifier against dry heated air, water sparingly, and shield it from drafts.
