Introduction
The crown of thorns plant, also known as Euphorbia milii, is a popular houseplant known for its beautiful flowers and easy care. In this guide, we’ll cover everything you need to know about growing and caring for this unique plant.
Symbolism and Folklore
In Thailand, the number of flowers on a crown of thorns plant is said to foretell the luck of its owner. Over the years, hybridizers have improved the plant to produce more and larger flowers, bringing even greater luck, according to the legend.
Growing Conditions
Crown of thorns plants thrive in warm, dry environments similar to their native habitat.
Light: Place your plant in a sunny window where it will receive at least three to four hours of direct sunlight each day.
Temperature: Average room temperatures between 65-75°F (18-24°C) are ideal. The plant can withstand temperatures as low as 50°F (10°C) in winter and as high as 90°F (32°C) in summer.
Watering: Water your plant when the soil is dry at a depth of about an inch, which is about the length of your finger to the first knuckle. Water the plant thoroughly and allow all excess water to drain out. In winter, allow the soil to dry to a depth of 2 or 3 inches before watering.
Feeding: Fertilize your plant with a liquid houseplant fertilizer every two weeks in spring, summer, and fall. In winter, dilute the fertilizer to half strength and use it monthly.
Repotting: Repot your plant every two years in late winter or early spring. Use a potting mix that drains quickly, such as a mix designed for cacti and succulents. Choose a pot that is large enough to accommodate the roots comfortably.
Special Care
Gloves: Wear gloves when working with crown of thorns plants, as the sap can cause skin irritation.
Toxicity: Crown of thorns plants are poisonous if eaten and should be kept out of reach of children and pets.
Long-Term Care
Pruning: Prune your plant to control its size and shape. Remove any dead or damaged stems, and trim back any long or leggy stems.
Propagation: Crown of thorns plants can be propagated by stem cuttings. Take a cutting from a healthy stem and allow it to callous over for a few days before planting it in potting mix.
Common Problems
Yellow leaves: Yellow leaves can be a sign of overwatering, underwatering, or nutrient deficiency.
No blooming: Crown of thorns plants need bright light to bloom. If your plant is not blooming, try moving it to a sunnier location.
Pests: Crown of thorns plants are susceptible to pests such as mealybugs and aphids. Treat infestations with an insecticidal soap or neem oil.

The crown of thorns plant is a beautiful and easy-to-care-for houseplant that adds a touch of elegance to any home. With proper care and attention, your crown of thorns plant will thrive for many years to come.
