Propagation of Euphorbia lucida Waldst. & Kit.
Euphorbia lucida Waldst. & Kit., also known as Shiny Spurge, is a perennial herbaceous plant native to Europe and Asia. It can grow up to 60 cm in height and has yellow-green flowers.
Seed Propagation
One of the propagation methods of Euphorbia lucida is through seeds. The ideal time to collect the seeds is in late summer or early autumn. The seeds can be stored for up to three years.
Before sowing the seeds, it is advisable to soak them in water for 24 hours. The soil for sowing the seeds should be well-draining and moist.

Germination typically occurs within two to three weeks.
Cutting Propagation
Another propagation method of Euphorbia lucida is through stem cuttings. The best time to take the cuttings is during the spring or early summer when the plant is actively growing.
The cutting should be about 5-8 cm in length and should have at least two nodes. The lower leaves should be removed, and the cutting should be allowed to dry for a day before planting. The cutting should be inserted into a well-draining soil mix and kept moist. The container should be placed in a warm and bright location.
Rooting typically occurs within three to four weeks. Once the roots have developed, the new plant can be transplanted into a larger container or directly into the ground.
Disease Management
Euphorbia lucida Waldst. & Kit. is generally a hardy plant that is resistant to most plant diseases. However, it can occasionally be affected by fungal and bacterial infections. Here are some common diseases that could affect the plant and how to manage them:
