Crassula cornuta: Care and Propagation Guide

Crassula cornuta is a small-sized succulent growing in tightly packed stems. The leaves are triangular and very thick. They are densely packed along the stems, giving the stem a columnar appearance.

It only grows to a height of 6 inches. Technically, it can grow flowers around the year when the conditions are suitable, but they mostly appear during the winter.

The flowers are extremely small and either white or light pink. They grow on small inflorescences a few centimeters above the stems.

How to Care for Crassula cornuta

Light

The Crassula cornuta succulent grows best when placed on a sunny windowsill because it needs strong and bright light and a bit of direct sunlight. For the plant to thrive, it should get full to partial sun.

If the plant doesn’t receive sunlight, it will have a spindly growth and will not flower. The Crassula cornuta is more of an outdoor plant rather than an indoor one.

Watering

Since the Crassula cornuta is a succulent, it has the same watering needs as other types of succulents. The plant needs proper watering to thrive and be healthy. You should take care not to overwater the plant and it must not sit in water.

The Crassula cornuta requires regular watering from April to September, which is its growing months; however, during the autumn and winter seasons, the plant goes into dormancy, when it must be watered very sparingly.

The best method to water the Crassula cornuta is by allowing the soil to dry out completely and then giving it a good soak.

Soil

The Crassula cornuta succulent grows best in gritty, well-drained soil. It does well in mineral soil having very low organic content. Adding pine bark or coconut coir to the soil helps to make the soil better draining.

Fertilizing

There is no need to fertilize the Crassula cornuta in general because this will cause the lush growth of the plant and spoil the sleek, sophisticated look that you want. The plant should be fertilized once every two weeks during the spring and summer months, which is its growing season.

Use a balanced liquid fertilizer that has been diluted by 50%. Avoid fertilizing the Crassula cornuta during winter.

Climate

The Crassula cornuta succulent thrives in warm climates and the perfect temperatures are between 60°F to 75°F (15.5°C to 24°C). In winter the temperature should not be less than 50°F (10°C). The succulent does not do very well in cold and damp weather and it tends to lose its color, turning mushy and yellow.

If you reside in an area with a cold climate, then it is better to grow the succulent indoors. However, you must ensure that it receives sufficient sunlight. The succulent grows in the USDA hardiness zone 9b to 11b.

Pests and Diseases

In general, the Crassula cornuta succulent does not have any serious disease or pest problems. However, overwatering can lead to fungal diseases and also cause the root of the plant to rot. The plant may also be susceptible to pests such as aphids and mealybugs.

Propagating Crassula cornuta

The Crassula cornuta succulent can be propagated by stem or leaf cuttings, leaves, basal offsets or seeds.

Leaves

If you are using leaves to propagate the succulent, make sure to get a healthy complete leaf from the mother plant. Let the leaf callous before replanting it. Replant it in well-draining soil and water when the soil is completely dried out.

Cuttings

Cut a stem cutting that is 2 to 3 inches long and plant it in a pot of 2 to 3 inches height having a mixture of sand and peat moss in equal quantities. Keep the plant at room temperature in bright light.

Offsets

When the mother plant produces an offset, remove it from the main plant using a sharp knife and clean the excess soil. Wait until the offset calluses and only then replant it in well-draining soil. Ensure to water it when the soil becomes dry.

Seeds

Propagating the Crassula cornuta using seeds is not a popular method because the growth is extremely slow. However, to propagate using seeds, sow the seeds in well-draining soil in autumn by mixing the seeds with some fine sand and spreading the sand on the surface of the soil uniformly.

Water once every few days and keep the soil moist until the plantlets appear. Then, allow the soil to dry out between the waterings.
