Propagation of Euphorbia buxifolia Lam.
Euphorbia buxifolia Lam. can be propagated through various methods such as:
Seeds
Seeds are the most common and easiest way to propagate Euphorbia buxifolia Lam. Collect mature and dry seeds and sow them in well-drained soil. Cover the seeds lightly with soil and water. Germination can take up to 2-3 weeks. The seedlings can be transplanted to their permanent location once they have developed true leaves.
Cuttings
