For planting from seeds, the soil should be well-draining and the seeds should be sown in shallow containers about 6 to 8 weeks before the last expected frost. Transplanting to the garden should be done after all frost danger has passed.
For propagation using stem cuttings, cut a stem that is about 3 to 5 inches long and has a few leaves. Dip the cut end in rooting hormone and plant it in a pot filled with well-draining soil. Keep the soil moist and the cutting will root within a few weeks.
Watering Needs

You can also pinch back the tips of stems to promote bushier growth.
Propagation of Euphorbia corollata L. var. angustifolia Ell.
Euphorbia corollata L. var. angustifolia Ell. can be propagated through a variety of methods, including seeds, stem cuttings, and division.
Seeds
Seeds are the most common method of propagation for Euphorbia corollata L. var. angustifolia Ell. Seeds should be planted in the fall or early spring in well-draining soil, and kept moist until they germinate. It is important to note that Euphorbia corollata L. var. angustifolia Ell. seeds have a low germination rate, so it is recommended to plant several seeds to increase the chances of success.
Stem Cuttings
Stem cuttings can also be used to propagate Euphorbia corollata L. var. angustifolia Ell. Cuttings should be taken in the summer, when the plant is actively growing. The cuttings should be around 4-5 inches long, with several leaves attached. The lower leaves should be removed, and the cutting should be treated with a rooting hormone before being planted in well-draining soil. The cutting should be kept moist until it roots, which usually takes around 4-6 weeks.
Division
Division is another method of propagating Euphorbia corollata L. var. angustifolia Ell. This should be done in the spring, when the plant is just starting to grow. The plant should be carefully lifted from the ground and the rootball should be divided into several sections. Each section should have several shoots and roots attached. The divided sections can then be planted in well-draining soil, and kept moist until they are established.
Disease and Pest Management for Euphorbia corollata L. var. angustifolia Ell.
Euphorbia corollata L. var. angustifolia Ell. is a hardy plant that can thrive in a variety of conditions. However, like all plants, it is susceptible to certain diseases and pests that can affect its growth and yield.

To prevent root rot, make sure the plant is kept in well-draining soil. Avoid overwatering and ensure that there is adequate airflow around the roots.
2. Powdery mildew: Powdery mildew is a common fungal disease that affects many plants, including Euphorbia corollata. It presents as a white, powdery coating on the leaves and stems of the plant. To manage powdery mildew, remove any infected leaves and dispose of them. Treat the plant with a fungicide, following the manufacturer's instructions carefully.
3. Leaf spot: Leaf spot is a fungal infection that presents as brown or black spots on the leaves of the plant. It can be caused by poor air circulation or overwatering. To manage leaf spot, remove any infected leaves as soon as possible. Treat the plant with an appropriate fungicide.
Pests
