Crown of thorns plants, also known as Euphorbia milii, can experience common problems that may affect their growth and overall health. It is important to address these issues promptly to ensure the plant thrives. In this section, I will discuss the top tips for caring for crown of thorns plants, including location, water requirements, and common issues that may arise.
Top Tips for Caring for Crown of Thorns Plants
Caring for crown of thorns plants, also known as Euphorbia milii, involves providing the right conditions for their growth and addressing common issues promptly. Here are some top tips for ensuring the health and well-being of your crown of thorns:
1. Provide a bright location with a few hours of sunlight per day
Crown of thorns plants thrive in bright locations with a few hours of sunlight per day. However, it is important to gradually increase their exposure to avoid sun-scorch. Place the plant in a spot where it can receive adequate light without being exposed to direct sunlight for extended periods.
2. Follow the “Drenches Between Droughts” watering method
Crown of thorns plants require periods of drought between watering. This means allowing the soil to dry out between waterings. To achieve this, water the plant thoroughly until water drains out of the bottom of the pot, and then wait until the soil is dry before watering again. Avoid overwatering, as it can lead to root rot.
3. Fertilize every two or three months with a ‘Cactus’ or ‘Houseplant’ labeled feed
To promote healthy growth and blooming, fertilize your crown of thorns plant every two or three months using a ‘Cactus’ or ‘Houseplant’ labeled feed. Follow the instructions on the fertilizer package for the correct dosage and frequency of application.
4. Repot every three years using a ‘Cactus & Succulent’ labeled potting mix
Every three years, it is recommended to repot your crown of thorns plant using a ‘Cactus & Succulent’ labeled potting mix. Keep the plant pot-bound, meaning the roots should fill the pot, to encourage optimal blooming. Repotting also allows for refreshing the soil and removing any potential root issues.
5. Keep an eye out for common pests and take appropriate measures
Common pests that can affect crown of thorns plants include Spider Mites, Mealybugs, and Scale. Regularly inspect your plant for signs of infestation, such as webbing, white fluff, or sticky residue. If you notice any pests, take immediate measures to control them, such as using insecticidal soap or wiping them off with a damp cloth.
| Issue | Symptoms | Possible Causes |
|---|---|---|
| Curled leaves and dried brown edges | Curled leaves and dried brown edges | Too little water and over-exposure to the sun |
| Root rot | Wilting, yellowing leaves, and a foul odor | Overly moist or waterlogged soil |
| Yellow leaves | Yellowing of leaves | Watering-related issues, light imbalances, and fertilization problems |
| Extremely low temperatures | Yellowed foliage and weakened growth | Exposure to extremely low temperatures |
| Insufficient dormancy period | Lack of flowering | Not providing an adequate cool and dry dormancy period |
Common Issues with Crown of Thorns Plants
While crown of thorns plants are generally low-maintenance, they can encounter a few common issues that may impact their health and appearance. It’s important to recognize these problems early on and take appropriate action to address them. Here are some of the most common issues you may encounter with your crown of thorns plants:
- Curled leaves and dried brown edges: If you notice curled leaves or dried brown edges on your plant, it could be a sign of inadequate watering or overexposure to the sun. Crown of thorns plants require periods of drought between watering, so be sure to follow the “Drenches Between Droughts” method to avoid overwatering.
- Root rot: Overly moist or waterlogged soil can lead to root rot in crown of thorns plants. To prevent this issue, ensure that the soil has proper drainage and avoid overwatering the plant.
- Yellow leaves: Yellow leaves can be caused by various factors, including watering-related issues, light imbalances, and problems with fertilization. It’s important to carefully monitor the watering schedule, provide adequate light, and use the appropriate fertilizer for your crown of thorns plants.
- Extreme temperatures: Crown of thorns plants are sensitive to extremely low temperatures, which can result in yellowed foliage and weakened growth. It’s crucial to keep these plants in a suitable indoor or outdoor environment where temperatures stay within their preferred range.
- Insufficient dormancy period: A lack of flowering in crown of thorns plants may be due to an insufficient dormancy period. These plants require a cool and dry dormancy period to stimulate blooming, so make sure to provide the necessary conditions for optimal flower production.
By being aware of these common issues and taking proactive measures to address them, you can ensure that your crown of thorns plants remain healthy and vibrant. Regular monitoring, proper watering, and providing a suitable environment will go a long way in maintaining the beauty of these stunning plants.
Table: Common Issues and Solutions for Crown of Thorns Plants
| Issue | Cause | Solution |

| Curled leaves and dried brown edges | Inadequate watering or overexposure to the sun | Follow the “Drenches Between Droughts” watering method and provide proper sun exposure |
| Root rot | Overly moist or waterlogged soil | Ensure adequate drainage and avoid overwatering |
| Yellow leaves | Watering-related issues, light imbalances, or fertilization problems | Monitor watering schedule, provide adequate light, and use appropriate fertilizer |
| Extreme temperatures | Exposure to extremely low temperatures | Maintain suitable temperature conditions for the plant |
| Insufficient dormancy period | Lack of cool and dry dormancy period | Provide the necessary conditions for dormancy to stimulate blooming |
Origins and Temperature Requirements of Crown of Thorns Plants
Crown of thorns plants, scientifically known as Euphorbia milii, trace their origins back to the island of Madagascar. These unique plants were introduced to the Middle East centuries ago, where they have since gained popularity for their striking beauty and resilience.
In their natural habitat, crown of thorns plants thrive in temperatures between 65°F and 85°F (18°C and 29°C). They prefer warm and sunny climates, making them ideal for indoor cultivation in regions with cooler or unpredictable weather.
It’s important to note that crown of thorns plants are sensitive to frost and should never be exposed to freezing temperatures. To ensure their well-being, it is best to keep them in a controlled environment where the temperature remains within their ideal range.
Temperature Management Tips:
- During warmer months, place the plant in a location that receives ample sunlight to meet its light and heat needs. Gradually increase exposure to avoid sunburn.
- During cooler months, provide a slightly cooler environment to mimic their natural dormancy period. Maintain a temperature range between 60°F and 65°F (15°C and 18°C) to encourage blooming.
- Avoid placing crown of thorns plants near drafty windows or doors, as sudden temperature fluctuations can lead to stress and damage to the plant.
By understanding the origins and temperature requirements of crown of thorns plants, you can create an optimal environment for their growth and ensure their vibrant and beautiful blossoms for years to come.
Propagation and Flowering of Crown of Thorns Plants
Now that we’ve covered the care and common issues of crown of thorns plants, let’s dive into propagation and flowering. Propagating these plants can be done through stem tip cuttings or seeds.
Stem tip cuttings are a popular method because they have a higher success rate when given the right conditions and care. Choose a healthy, non-flowering stem and make a clean cut just below a leaf node. Allow the cutting to dry for a day or two, then place it in a well-draining potting mix. Keep the soil slightly moist but avoid overwatering. With patience and proper care, you’ll see roots forming in a few weeks.
When it comes to flowering, crown of thorns plants bloom between late spring and late summer. Each individual bloom can last up to two weeks, creating a beautiful display of vibrant colors. However, achieving a bloom requires specific temperature and watering adjustments. During the dormancy period, keep the plant in a cool and dry environment. This will help stimulate the flowering process. Additionally, adjusting the temperature and reducing watering frequency can help trigger blooming.
By following these tips, you can enjoy the process of propagating crown of thorns plants and witness their stunning blooms. Remember to provide the right conditions and care to ensure a successful propagation and a flourishing plant.
