Everything it needs
9 essentials at a glance
Watering
Water the Calico Plant when the top inch of soil feels dry, typically every 1-2 weeks.
In warmer months, increase frequency to once a week. Ensure the pot has drainage holes to prevent waterlogging. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and crispy leaf edges.
Light
The Calico Plant thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive 6-8 hours of light daily. Too little light can lead to leggy growth, while too much direct sun may scorch the leaves.
Soil
This plant prefers a well-draining potting mix with a pH range of 6.0 to 7.0.
A mix of peat, perlite, and vermiculite is recommended to ensure good drainage and aeration. Avoid heavy soils that retain too much moisture.
Humidity
The Calico Plant enjoys higher humidity levels, ideally between 50-70%.
To increase humidity, consider using a humidity tray or a humidifier. Signs of low humidity include browning leaf tips and leaf drop.
Temperature
Ideal temperatures range from 65-80°F (18-27°C).
It is sensitive to cold and should be protected from temperatures below 50°F (10°C). The plant is best suited for USDA hardiness zones 10-11.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune the Calico Plant in early spring to encourage bushier growth.
Use clean, sharp scissors to remove any dead or leggy stems. Deadheading spent flowers can also promote new growth and maintain appearance.
Repotting
Repot the Calico Plant every 1-2 years or when it outgrows its pot.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. Gently remove the plant from its pot, loosen any tightly bound roots, and place it in fresh potting mix.
Propagation
Propagation can be achieved through stem cuttings.
Take a 4-6 inch cutting from a healthy stem, remove the lower leaves, and place it in water or moist soil. Keep it in a warm, bright location until roots develop, which usually takes 2-4 weeks. The best time for propagation is in spring or early summer.
