Miniature Caladium (Caladium humboldtii) belongs to the Araceae family and is a demanding houseplant to look after. This moderate grower plant is happiest in bright, indirect and reaches 15–25 cm indoors.
For watering, the rule is simple: keep evenly moist. In the growing season it needs water roughly every 4 days, dropping to every 12 days in winter. Use the watering calculator below to tune that rhythm to your pot size, light and household humidity.
Important: Miniature Caladium is toxic to pets — keep it out of reach of cats, dogs and children.

Let the top 2–3 cm dry and finger-check before watering again.
Miniature Caladium prefers bright, indirect but will cope with medium, indirect. Harsh midday sun can scorch sensitive leaves, while too little light leads to leggy, sparse growth.
Keep Miniature Caladium between 18–27 °C and aim for around 60% humidity (40% minimum). Below 12 °C it risks cold damage — keep it away from draughty windows and radiators.

Soil between waterings
Pot Miniature Caladium in chunky, airy aroid mix (bark, perlite, coco coir). A drainage hole is essential — soggy, airless soil is the single most common way houseplants die.
Contains insoluble calcium oxalate crystals. Chewing causes intense oral burning, drooling and swelling in cats, dogs and people. Keep out of reach.
The best ways to propagate Miniature Caladium are stem cuttings, water-rooting nodes, division and air layering. Late spring and summer are ideal, when the plant is growing most actively.
The natural holes and splits in aroid leaves (fenestration) let wind and light pass through to lower leaves in the rainforest canopy.
In the growing season Miniature Caladium needs watering 2–3 times a week (about every 4 days in a 16 cm pot at medium light), and much less in winter — roughly every 12 days. Use the watering calculator above to get the exact interval for your conditions.
Miniature Caladium thrives in bright, indirect. A spot near a bright window out of harsh midday sun is ideal; give it a little more light in winter.
