Before learning about coral cactus care tips, let’s solve two of the most common problems that a lot of coral cactus owners have:

Coral Cactus Brown Spots

Coral cactus brown spots are a common problem among coral cacti. Coral cactus brown spots are caused by root damage due to excessive watering. If the plant’s pot has no drainage hole, root rot and coral cactus brown spots are inevitable too.

Coral Cactus Dying

Similar to coral cactus brown spots, the problem of coral cactus dying is because of improper watering as well (both over and under-watering). So water on time, and water the soil directly, not the plant.

Euphorbia Coral Cactus Care

Euphorbia lactea cristata, also known as coral cactus, is a type of Euphorbia plant from the family Euphorbiaceae. Crown of Thorns (Euphorbia Milii), African Milk Tree, and Euphorbia caput-medusae are among the plants that the coral cactus is related to.

The long-lived and perennial Euphorbia lactea cristata originates from the nurseries of experimental horticulturists. As it’s in fact a grafting of two types of Euphorbia: Euphorbia lacteal (crest), and Euphorbia neriifolia (root and stock).

This houseplant has an eye-catching crest-like shape very similar to ocean coral, explaining its most famous common name. Other common names for this coral cactus include Crested Candelabra, Crested Euphorbia, Candelabra, and Crested Elkhorn.

Coral Cactus Care Tips

Euphorbia lactea is a small houseplant that hardly grows more than about 2 feet in size. The unusual foliage of coral cactus green leaves of the fascinating plant is truly striking. The upper crest with ruffled edges is green, red, purple, white, or yellow.

The coral cactus flower is also rare in this plant. Even when it produces a coral cactus flower (when it’s at least a year old) in the spring, it will be very small and hard to notice. The tiny coral cactus flowers are pink or purple. In the following, you’ll find coral cactus care instructions.


Check the soil every now and then, and when the top 2 inches is dry, water your houseplant deeply. Remember that the coral cactus needs more water during its active growing seasons (spring and summer), and less during cold months.

The important thing in coral cactus care regarding water is to avoid excessively dry and excessively wet soil. The first situation causes your houseplant to wither and has an irreversible effect. The latter also causes root and stem rot.


Euphorbia lacteal enjoys bright, indirect sunlight. If kept indoors, a south-facing bright window is a suitable spot. Make sure to turn your Crested Elkhorn occasionally to prevent having it grow in an unequal manner. If kept outdoors, it grows best in full to partial sun.

If you live in a very hot area, we recommend a location with bright, indirect sunlight like under trees or on a covered patio. If you keep the coral cactus indoors during the cold months and move it outdoors in warm months, do it gradually to avoid burning delicate tissues.

Soil and Feeding

Crested Euphorbia tolerates all soil pH levels. To provide suitable soil in the coral cactus care, you need to go for gritty and well-draining potting soils. You can create it yourself by mixing coarse sand and high-quality soil in equal amounts. If that’s not possible, simply use cactus soil or succulent potting soil.

A balanced 10-10-10 liquid fertilizer which is diluted to ¼ strength is recommended for monthly fertilization during spring and summer. So don’t fertilize during the fall and winter at all. Also, avoid using granular fertilizer or slow-release fertilizer, as they can damaging the coral cactus’s roots.


In Euphorbia coral cactus care, the ideal temperature is between 60° to 85° degrees Fahrenheit or 15° to 30° Centigrade. If the temperature outside drops below 50° degrees Fahrenheit or 10° Centigrade, bring your coral cactus indoors, as it’s not very winter hardy.


A coral cactus for sale is usually planted in a ceramic container. It may also have a solid mulch of gravel glued together over the top. We think that you should transparent your plant to a new pot as soon as you can for the best coral cactus care. Apart from this situation, you’ll rarely need to repot is as it is very slow-growing.

Ceramic containers don’t provide good air circulation for the roots. Additionally, the solid gravel mulch will prevent you from being able to check the soil moisture before irrigations.

Coral Cactus Pests

Following the coral cactus care tips regarding good airflow, humidity, etc., your plant won’t have any problems. Although it’s notable that the latex sap of the coral cactus itself protects it against pests. If you can’t provide ideal coral cactus care, it may suffer from common pests like mealybugs, scale insects, spider mites, and fungal infections.

If you notice this problem soon enough, you can remove mealybugs and scale insects by simply wiping them off with a cotton swab and 70% isopropyl alcohol. Don’t apply higher concentrations of alcohol as it may burn the coral cactus green leaves and its flesh.

To eliminate spider mites and their eggs, wash them away with the help of a strong spray of water. And for heavy infestations, a diluted Neem oil spray solution can solve the problem.


Common coral cactus diseases are powdery mildew, root rot, and stem rot. For powdery mildew, mix a tablespoon of baking soda with a gallon of water and spray your Crested Euphorbia with it. To help to solve this problem, increase the air circulation around the plant, and reduce humidity as well.

For fungal rots, cut away any mushy, brown parts of the plant and its roots with a clean and sharp knife.  Keep in mind that you don’t need to apply fungicides to the wounds because the plants’ latex sap itself has fungicidal properties.
