Callisia

Callisia plants should be watered once the top layer of soil (approximately two to three inches) is dry. As with most houseplants, it's important to water the callisia properly. Too much water can cause root rot and the plant to die; though if the soil is too dry the roots will also suffer. The water should be room temperature and applied gently so as not to disturb the soil.

Callisia plants prefer bright, indirect light. When placed in direct sunlight, the foliage can become discolored and burn. Start with medium light and move a callisia to a more shaded spot if leaves are discolored or burned. If the houseplant is moved to a less shaded spot, it can cause sunburn. Too little light will cause the flowers to fade and the scene will become less lush.

Callisia plants prefer temperatures between 60 and 80°F (15.6 - 26.7°C), but can tolerate lower temperatures as long as they’re not exposed to extreme cold. If temperatures drop below freezing, the plant may die.

Callisia plants thrive in humid conditions, which is why they make great houseplants. Humidity levels around 60-70% are ideal, but if indoors, use a room humidifier or a damp towel to improve the area around the plant.

Callisia plants prefer richly organic, slightly acidic, and well-draining soil. Potting soil with added peat moss and coarse sand or perlite makes an excellent choice for repotting.

Callisia plants require fertilization every two to three months from early spring to late summer. Use a balanced liquid fertilizer for houseplants, diluted to the recommended strength and applied every two weeks. Avoid fertilizing too late in the summer, as this can stimulate new growth, which won't have enough time to harden before the winter comes.

Callisia plants are susceptible to attacks from common houseplant pests, such as aphids, mealybugs and spider mites. These pests feed on the sap from leaves and stems, causing yellowing or discoloration of foliage. To control them, the use of insecticidal soaps and horticultural oils can be effective. Be sure to apply treatments to top and bottom surfaces of leaves and stems to get rid of the pests completely.

Callisia plants require repotting every 2-3 years, as they tend to become root-bound quickly. When repotting, make sure to use a fresh, well-draining potting mix. Repot during the spring, when the weather is warmer and the soil is most accommodating.

Because they’re a trailing plant, callisia requires occasional pruning to keep it looking its best. Pruning should be done every few months to remove damaged, discolored, or dead leaves and stems. If necessary, remove entire weak or dead vines.

Mulching callisia plants is beneficial because it helps keep the soil moist, prevents weeds from growing, and improves soil nutrient availability. Use organic mulch such as shredded bark or wood chips in the top layer of soil, and add top dressing every couple of months.

Callisia plants can be propagated quite easily by stem cuttings. Take the cutting from a healthy stem and remove the lower leaves. Place the stem into soil (mixed with sand or perlite) and water. Ensure that the soil is kept evenly moist at all times and in a few weeks, roots should begin to appear.

Callisia plants do not require any support structure, but if necessary, provide support with a layer of soil underneath the roots. This makes sure the plant has room to put down deeper roots and remain upright and healthy.

Callisia plants require a rest period during the winter months, when the plant should be allowed to dry out somewhat in between waterings. During the winter, the plant will grow more slowly and require less water.

Callisia plants can be toxic to pets, so keep them away from your furry friends.
