As a general rule, euphorbia requires well-drained soil in full sun. A few tolerate shadier conditions, but none of the family is fussy about soil condition. They even thrive in very poor soils and can tolerate periods of drought. Euphorbia plant care is simple. Provide them light, moderate moisture and watch for annoying pests, like whitefly. Provide water under the plant’s leaves to prevent powdery mildew. You will not need to fertilize it often. Wait until the bottom leaves become yellow before feeding with a water-soluble plant food. Prune when the plant gets out of hand. These plants are almost impossible to kill and are a perfect choice for the novice gardener. Growing Euphorbia to share with a friend is also a great beginner propagation project.
