Coral Cactus

Coral Cactus does not need intense irrigation. Watering regimes should be moderate, always letting the substrate fully dry between every watering. Overwatering can cause the plant to rot. During summer, watering may be increased slightly, especially if it is placed outdoors. In winter, it requires drastically reduced watering since the temperatures are lower and the evaporation rate and transpiration are not as intense.

Coral Cactus is a tropical plant that, to develop its characteristic coloration, requires a lot of light, so it needs to be placed in a luminous and well-ventilated area. Evidence of insufficient quantities of light are yellowish leaves or lack of the characteristic gray color. Without light it will stretch out and gradually become weaker. Direct sunlight is not recommended but it does appreciate natural indirect light.

Optimal temperature for optimal growth of Coral Cactus range from 65 ℉ - 75℉ (18℃ - 24℃) in summertime and from 40℉ - 60℉ (5℃ - 16℃) in the winter. Any temperatures below 40℉ (5℃) may cause freezing and cracking in the plant.

Coral Cactus is used to arid climates, so high humidity levels may pose a challenge for the plant. It is recommended to use a dehumidifier in your home if needed. Furthermore, the plant may benefit from a weekly misting with warm water.

Coral Cactus prefers a light, well-draining soil mix. Commercial succulent soil mixes work best, but you can easily craft your own with a good combination of ingredients such as perlite, sand, coco peat and other types of potting substrates. Good quality potting mixes ensure proper rooting and help the plant develop vigorous growth.

Coral Cactus should be fertilized once a month during the spring and summer months. An appropriate cactus or succulent fertilizer should be used. During winter, fertilization is not recommended since the plant doesn’t require as much food during this time.

Coral Cactus is quite resilient to common pests. However, it may be affected by aphids, mealybugs or mites. To get rid of these pests it is recommended to use natural products such as Neem oil, potassium soap or insecticides. In any case, it is important to act as soon as the presence of pests is detected in order to contain their spread and prevent damages to the plant.

Repotting needs to be done every two to three years. The best time to repot is during the springtime. Be aware that the stem of the Coral Cactus is quite fragile, so it is important to handle the plant with care when repotting. Make sure to use a well draining potting mix in order to protect the roots from excessive moisture.

Pruning is not recommended for Coral Cactus as it may damage the stem of the plant. If it is absolutely necessary, small and tender stems may be cut off using clean and sharp scissors or pruning shears. If a bigger branch is to be cut off, it is important to make sure that no cuts are made outside the branch to prevent infection of the plant.

Mulching is not recommended for Coral Cactus since it can attract pests in the summer and retain too much moisture in the soil in the winter.

Coral Cactus can be propagated by cutting it at the base of its main stem. Let the cut dry for a few days and then plant it in a fresh potting mix. Keep in a warm and humid environment, and with a good amount of light, to promote root growth. Do not water the plant for a few days after planting.

Due to its tall stem, Coral Cactus may require some external support when grown indoors. A stake or cane can be used for this purpose.

Coral Cactus does not usually go into a rest period. This means that even during winter it will continue to be light green in color and show signs of growth. However, it is important to reduce its watering during this season.

Coral Cactus is toxic for both pets and humans. Its sap contains latex; an irritating substance that can cause skin and eye irritation. It is also toxic if ingested and can cause coughing, difficulty breathing and abdominal pain.
