Crown of Thorns Plant Sunlight: Do They Need It and How Much?

Crown of Thorns Plant Soil Tips
These plants prefer well-draining, sandy or loamy soil with a pH between 6.0 and 7.5. A mixture of equal parts potting soil, coarse sand, and perlite or pumice works well. Ensure the soil drains quickly to prevent root rot, which can occur if the plant sits in soggy soil for extended periods.
Crown of Thorns Plant Watering and Frequency
Water your Crown of Thorns Plant sparingly, allowing the soil to dry out between waterings. Overwatering can lead to root rot and other problems. In the summer months, water your plant every 7-10 days, while in the winter, reduce watering to every 3-4 weeks. Always use a well-draining container to prevent waterlogged soil.
Pruning Crown of Thorns Plant Properly
Prune your Crown of Thorns Plant as needed to maintain its shape and remove any dead or damaged growth. Regular pruning can also encourage bushier growth and more flowering. When pruning, be sure to wear gloves and protect your skin from the plant’s milky sap, which can be irritating to some people.
Optimal Crown of Thorns Plant Temperature: Can They Tolerate the Cold?
Crown of Thorns Plants prefer warmer temperatures and cannot tolerate prolonged exposure to temperatures below 50°F (10°C). If you live in a region with cold winters, grow your plant in a container and bring it indoors during the colder months. Place it near a bright window and maintain a consistent temperature to keep your plant healthy and happy.

Overwatering can lead to root rot, a potentially fatal condition for your plant. To avoid root rot, allow the soil to dry out between waterings and ensure your plant is in a well-draining container. If you notice signs of root rot, such as yellowing leaves or a foul smell, you may need to repot your plant in fresh, well-draining soil.
