Euphorbia grandidens, commonly known as valleybush euphorbia or large-toothed euphorbia, is a species of plant in the family Euphorbiaceae native to southern Africa.
Cow horn has moderate resistance to disease but is more vulnerable to humidity and excess watering. It is also likelier to develop illnesses when it receives insufficient light and is overwatered. Regarding maintenance, Cow horn tolerates drought and can go long stretches without water. It requires little fertilizer and only needs pruning occasionally. Because of this, it suits people at any experience level, particularly those who prefer to spend less time on plant care or who may be away from home for extended periods. It’s a solid option for anyone who does not want to devote a lot of time to plant maintenance yet still wants an easy-to-care-for specimen.
How to keep Euphorbia Grandidens.
Light
Native to arid regions, Cow horn does best in full sun, its native habitat marked by intense sunlight and very little shade. It can also tolerate partial sun, giving it some flexibility in how it grows.
Temperature
Cow horn is native to regions with a hot climate and thrives at temperatures of 68 to 100 °F (20 to 38 ℃). In cooler seasons, providing a warmer environment is recommended.
Fertilizer
Light applications of fertilizer once or twice a year during the growing season are enough for Cow horn. Do not fertilize in winter or summer when it is dormant. Cut back on fertilizer after repotting and wait a couple of months following repotting before applying any. Fertilizing helps maintain healthy growth and encourages blooms.
