How to care for your Croton

Everything you need to keep your Croton healthy: watering, light, humidity, feeding, repotting and pruning.

Codiaeum variegatum is native to Southeast Asia, Malaysia, and the western Pacific islands. Its leathery, glossy leaves come in a festival of colors including bright red, orange, golden yellow, deep green, and purple, often mixed on a single leaf. Leaf shapes also vary among cultivars: narrow and spiraled, broad and lobed, or long and ribbon-like. This demanding plant needs plenty of light to maintain its vivid colors and dislikes cold drafts, which cause leaf drop.

Watering your Croton

Every 5 days

Keep soil evenly moist during the growing season. Water when the top 1–2 cm is dry. Use lukewarm water. Never let the soil dry out completely or become waterlogged.

How to know it needs water

Top 1–2 cm of soil feels dry
Leaves begin to droop and wilt
Lower leaves drop prematurely

How much light a Croton needs

Full sun

Bright direct or indirect light essential for vibrant colors. In low light, leaves revert to green and drop. At least 4–6 hours of bright light daily.

Direct sun tolerated: 4 to 6 h a day
Orientations that suit it: South, South-east, South-west, East, West

Humidity and misting

50–70 %

50–70% Requires consistent humidity. Mist regularly and wipe leaves to prevent spider mites, to which crotons are very susceptible in dry air.

Feeding and fertiliser

Every 14 days

Feed every two weeks in spring and summer at half strength. Reduce to monthly in autumn. No feeding in winter.

Recommended feed: Balanced slow-release or liquid fertilizer (10-10-10) · 3-1-2

Repotting your Croton

Every 24 months

Use rich, well-draining potting mix. Wear gloves as the milky sap can irritate skin. Handle gently — crotons dislike being moved and may drop leaves from shock.

When: Spring
Potting mix: All-purpose potting mix
Mix in: perlite, coco fibre

The tell-tale signs

Roots growing from drainage holes
Plant drops lower leaves excessively
Soil dries out very quickly after watering

Pruning your Croton

Spring, or when the plant becomes leggy or too tall. Cut stems at the desired height. Wear gloves due to irritating sap. Dab cuts with charcoal to stop sap flow. The plant will branch below the cut.

Through the year

Watering is not set once and for all: it follows the light and the growth. Allow 7 days between waterings in the depth of winter, against 4 in the growing season.

Toxicity

Milky sap can irritate skin and is toxic to cats and dogs if ingested, causing vomiting and diarrhea. Mildly irritating for humans but not considered seriously toxic.

Good to know

The croton is one of the few houseplants whose foliage rivals flowers in color: red, orange, yellow, pink, and purple can all appear on a single leaf.
Crotons are extremely sensitive to change — simply moving one to another room can trigger a dramatic but temporary leaf drop.
