Propagation of coral succulents, also known as Euphorbia lactea cristata or coral cactus, is a unique process compared to other succulents. This plant is actually a combination of two different species, Euphorbia neriifolia and Euphorbia lactea var., which makes it unable to reproduce through traditional methods such as leaf or stem cuttings. However, it can be propagated through grafting.
Grafting is a technique that involves joining the tissues of two plants together so that they grow as one. This method allows us to create new coral cactus plants by combining a Euphorbia neriifolia rootstock with a Euphorbia lactea var. crest, also known as the scion.
Here is a step-by-step guide on how to propagate coral succulents through grafting:
1. Choose healthy parent plants: Select a healthy Euphorbia neriifolia as your rootstock and a desirable Euphorbia lactea var. crest as your scion. It’s essential to ensure that both plants are disease-free and in good condition.
2. Prepare the rootstock: Take a clean and sharp knife or razor blade and make a clean, diagonal cut on the top of the Euphorbia neriifolia rootstock. This cut should be around 2-3 inches long and should create a flat surface for grafting.
3. Prepare the scion: Similarly, make a clean, diagonal cut on the bottom of the Euphorbia lactea var. crest scion. This cut should match the cut made on the rootstock, creating a perfect fit when joined together.
4. Join the two plants: Carefully place the cut surface of the scion onto the cut surface of the rootstock, ensuring they align perfectly. Press them firmly together to create a tight bond. You can use grafting clips or tape to hold the two plants in place while they heal.
5. Protect the graft: To prevent infection or damage, apply a thin layer of grafting wax or sealing compound over the graft union. This will help keep the tissue protected and promote successful healing.
6. Provide optimal conditions: Place the grafted plant in a warm, bright location, but avoid direct sunlight. Maintain a temperature around 70-75°F (21-24°C) and provide indirect light to encourage healing and growth.
7. Monitor and care for the graft: Check the graft union regularly to ensure it remains intact and free from infection. Avoid overwatering the plant, as excess moisture can lead to rot. Wait until the graft has fully healed and new growth appears before gradually acclimating the plant to more sunlight.
It is worth noting that grafting can be a challenging technique and may require some practice to master. It’s essential to be patient and attentive during the process to increase the chances of success. If you’re new to grafting, it may be helpful to seek guidance from experienced gardeners or horticulturists.
Propagating coral succulents, or Euphorbia lactea cristata, involves grafting a Euphorbia lactea var. crest onto a Euphorbia neriifolia rootstock. This method allows for the creation of new coral cactus plants with their unique and captivating forms. By following the steps outlined above and providing appropriate care, you can successfully propagate these fascinating succulents and enjoy their beauty in your garden or indoor collection.
