Gardening Questions And Answers
If you’re looking for a plant that thrives in the conditions inside most homes, try the crown of thorns plant (Euphorbia milii). Growing the plant is easy because it adapts well to normal room temperatures and in dry indoor environments. It also forgives occasional missed waterings and feedings without complaint.
The only well-known predator of adult crown-of-thorns starfish was the Pacific triton, a giant sea snail that hunts by injecting venom. Dozens of coral fish had been identified as predators of the starfishes’ sperm, very young starfish, or were observed dining on dead or almost-dead adults, according to the paper.
Its longevity has an inverse relationship with dropping temperatures, with Crazy Plants, Crazy Critters saying that temperatures below 50 degrees will cause stress to the plant. Missouri Botanical Garden takes it one step further, saying the crown of thorns will react poorly when temperatures drop below 35 degrees.
Although Crown of Thorns belongs to the species of succulents, it can only store a limited amount of water using its stems. The plant has evolved to also take in water through the leaves, so misting the plant on a daily basis may help. As with all succulents and cacti, provide the soil with excellent […]
All parts of the Crown-of-Thorns plant are poisonous. Generally this group of plants is not appetizing to most animals but they will eat it if their normal food supply becomes limited. Drying does not destroy the toxicity of the plant, and Euphorbia in hay may be slightly more palatable to livestock.
Water crown-of-thorns regularly. A weekly schedule is not excessive if soil is permitted to dry to the depth of an inch between waterings. Overwatering can result in spongy stems, leaf loss and failure to bloom. In addition to testing soil for moisture, watch for leaf-droop as a signal that more water may be needed.
Crown of Thorns plants are woody with sharp spines. They have dark green, tear-shaped leaves that appear primarily on new growth on thorn-covered branches. When put under stress, such as a lack of moisture, the plant may defoliate completely, but will produce new leaves when watered and new growth resumes.
In colder climates, crown of thorns makes a good houseplant. Unfortunately, it can be impacted by a disease called bacterial leaf spot, caused by bacteria called Xanthomonas. Spotted crown of thorns plants may be suffering from this bacterial disease, but spots can also be caused by fungal infections and injury.
