In Thailand, it is believed that the number of flowers on a Euphorbia crown of thorns plant foretells the luck of the plant keeper. Over the past two decades, hybridizers have improved the plant, allowing it to produce more and larger flowers, and if the saying holds true, bestowing better luck upon its caretakers. In the right settings, hybrids of Euphorbia, commonly known as the crown of thorns, can bloom almost year-round.

Growing Crown of Thorns Indoors If you're seeking a resilient plant that thrives in the typical home environment, the crown of thorns (Euphorbia milii) is an excellent choice. Caring for this plant is relatively straightforward, as it adapts well to normal room temperatures and dry indoor conditions. It also forgives the occasional missed watering or feeding without complaint.

The key to successful crown of thorns houseplant care begins with proper placement. Locate the plant in a very sunny window, where it will receive three to four hours of direct sunlight each day. The optimal temperature range for this plant is between 65-75 F. (18-24 C.), though it can withstand temperatures as low as 50 F. (10 C.) in winter and as high as 90 F. (32 C.) in summer.

Crown of Thorns Growing Care From spring through late fall, water the crown of thorns plant when the soil is dry to a depth of about an inch (2.5 cm.), which is approximately the length of your finger to the first knuckle. When watering, flood the pot with water and then empty the saucer underneath, ensuring the roots are not left sitting in excess moisture.

During the winter months, allow the soil to dry to a depth of 2 or 3 inches (5-7.5 cm.) before watering. Supplement the plant's care with a liquid houseplant fertilizer, applying it every two weeks in spring, summer, and fall. In winter, dilute the fertilizer to half strength and use it monthly.

The crown of thorns plant is hardy in USDA Hardiness Zones 9-11, reaching a mature size of 3-6 feet (0.9-1.8 m) tall when grown outdoors. Indoors, the plant typically reaches a height of around 2 feet (0.6 m).

Sunlight Requirements The crown of thorns plant thrives in full sun or partial shade. Providing the plant with at least three to four hours of direct sunlight each day is essential for its optimal growth and flowering.

Soil Preferences Well-drained soil is a must for the crown of thorns plant. Avoid using heavy, dense soils that can become waterlogged, as this can lead to root rot and other issues. Instead, opt for a well-aerated, fast-draining potting mix or a combination of potting soil and sand or perlite.

By following these guidelines for crown of thorns care, you can cultivate a vibrant and enchanting houseplant that may even bring a touch of luck to your home.
