How to Care for Euphorbia Leuconeura
Generally, E. leuconeura do not require pruning or repotting. If you repot your E. leuconeura, mix a light, well draining soil by blending 2 parts potting soil with 1 part perlite. E. leuconeura is easily propagated from seeds; however, the seeds must be planted quickly. Place gauze over the plant to capture the seeds when the seed capsules burst. E. leuconeura tolerates more water than many Euphorbia; however, do not leave the flower pot standing in water.
Always wear gloves and safety glasses when working with Euphorbia plants. The sap is caustic, causing skin reactions and severe corneal burns if you get it in your eyes. All parts of Euphorbias are poisonous; keep out of reach of children and pets.
Euphorbia leuconeura, also known as Madagascar Jewel, is a member of the Euphorbia family. With over 2,000 species, this family of cactus-like succulents includes a huge variety of plants such as the poinsettia, crown of thorns and African milk tree. E. leuconeura is believed to originate from Madagascar, although it appears that all known specimens are cultivated by nurseries and plant enthusiasts. Easy to grow, E. leuconeura is one of the Euphorbias that "shoot" seeds from capsules that burst abruptly when ripe. Like most Euphorbias, it also weeps a milky sap when its leaves or stem are injured.
Place the flower pot in a warm, brightly lit location. Avoid direct sunlight, as it may burn the leaves.
Water once a week during the growing season. In winter, water once or twice a month. Increase the humidity in the air by placing the flower pot on a tray filled with pebbles and water.
Fertilize with a balanced fertilizer suitable for succulents according to the manufacturer's directions.
Monitor your E. leuconeura for pests such as mealy bugs, spider mites and white flies. Spray with a solution of 1 tablespoon mild dishwashing liquid mixed with 1 gallon water.
