How Do You Care for Euphorbia Milii?

Euphorbia Milii, also known as Crown of Thorns, is a beautiful flowering plant that is native to Madagascar. It is a popular houseplant and is often used in landscaping. The plant gets its name from its thorns, which are actually modified leaves.

The plant produces a milky sap that can be irritating to the skin. Euphorbia Milii is a drought-tolerant plant and can survive in a wide range of climates. It prefers well-drained soil and full sun to partial shade.

The plant can be propagated from seed, cuttings, or division. It is important to wear gloves when handling the plant, as the sap can cause irritation. To care for

Provide your crown of thorns plant with bright, direct sunlight, temperatures ranging from 65 to 90 degrees Fahrenheit (18 to 32 degrees Celsius), low humidity, and fast-draining sandy soil.

Water when the top inch of soil is dry, prune to preserve shape, and fertilize lightly every 2-3 weeks with a low nitrogen fertilizer.

  • Requirements for lighting: The sun is shining brightly.
  • Water only when the top inch of soil is dry. Can withstand being submerged but will drop its leaves.
  • Soil: Cactus potting mix or mix equal parts potting soil, gritty sand, and perlite to make your own.
  • 65-90°F (18-32°C) is the recommended temperature. Below 60°F (15°C), leaves may begin to fall off.
  • Fertilizer: A succulent formula with low nitrogen and NPK values, such as 2-4-7 or 3-4-5, is appropriate. Higher nitrogen levels will enhance foliage but not blooming.
  • Humidity ranges from low to medium. It’s not fussy.
  • Pruning: This plant responds nicely to pruning to shape it. Wear gloves because sap is a skin irritant.
  • Propagation: Stem propagation is really simple. Seed propagation takes longer, but it is extremely doable.
  • Re-Potting: Rootbound blooms better. Wait until the plant has outgrown the pot before repotting.
  • Diseases and pests: Highly resistant to pests and diseases. The most serious issue is overwatering, which causes root rot.

Water your plants one or two days before taking cuttings to ensure that the cuttings’ stems have enough water.

Check to see if the stems you cut have leaves on them. To stop the sap from flowing, spray the cut end with cool water. The sap can irritate your skin and stain clothing and furnishings; you should wear gloves and wear eye protection.

Place the cuttings on a paper towel for 2-3 days to allow the wound to callous over, which is necessary for the cutting to root. Remove the majority of the leaves from the cuttings, leaving 3 or 4 on.

At this time, keep the cuttings out of direct sunlight. Plant in a well-draining soil mixture. You may hear about various blends, but the most crucial aspect is proper drainage. Drainage can be improved by using horticulture sand (not beach sand) or perlite.

After filling the pots with potting mixture, make a 1 1/2-inch-deep hole with a pencil or your finger. Pour a small amount of rooting hormone powder into a small container and dip the cut end into it—just enough to coat it, not more.

Any remaining hormone powder should be disposed away. Insert the powdery, cut end into the hole, then firm the dirt around the cutting gently.

After you’ve completed, place the container in a bright light but out of direct sunlight, and water the cutting sparingly.

Then, every several days, irrigate just enough to keep the soil moist. (Do not water as you normally would because the young plant does not yet have roots to take water from the soil and you risk rot.) It will take several weeks for the cutting to root and establish itself.

When you notice new growth, you can resume normal watering. That’s all!

How do you prune Euphorbia Milii?

The viability of Euphorbia milii seeds does not appear to be very lengthy, and they are best planted very quickly in an open mix and lightly covered.

They will germinate in a week or two if kept warm and wet.

You can start seeds in community pots and transplant them once they have a few genuine leaves. Plug trays are also useful.

How do you fertilize Euphorbia Milii?

In the spring and summer, feed the plant lightly with a balanced, organic houseplant fertilizer once or twice a month, continuing until the blossoms fade. Use a low nitrogen fertilizer on these plants and avoid fertilizers with boron micronutrient concentration, as some cultivars are sensitive to it.

Overfertilization can lead to decreased bloom yield. Some cultivars naturally have light leaf color, which does not imply a nutrient lack.

How do you make Euphorbia Milii bloom?

Crown of thorns plants requires a lot of bright, direct sunlight as well as a lot of water to produce the greatest flowers.

Excessive fertilizer, particularly high nitrogen preparations, can possibly inhibit flowering by promoting green growth at the expense of flowers.

Is Euphorbia Milii poisonous to dogs?

Yes, Euphorbia species, sometimes known as spurges, are harmful to both humans and pets. Poisonous compounds are most concentrated in the milky white fluid known as latex, but any part of the cut plant might produce symptoms.

The plant itself has been shown to be an effective molluscicide and a natural pest management method. The World Health Organization (WHO) has recommended using Euphorbia milii to help manage snails.

Particularly in endemic countries. Schistosomiasis is an infectious disease caused by freshwater parasites that are transmitted by snails. To avoid being infected by a parasite, extracts from the plant are used to reduce the snail population.


When it comes to generating medications for diseases, medicinal plants are extremely significant to humans. There are around 300 genera and 7,500 species in the Euphorbiaceae family, each with its own distinct therapeutic benefit.

Where is Euphorbia Milii found?

Euphorbia milii is a tropical and temperate evergreen shrub native to Madagascar that is frequently cultivated as an ornamental. It has escaped cultivation and can now be found in disturbed regions bordering farmed areas and dry thickets.

Why is my Euphorbia Milii yellow?

Many distinct environmental conditions can cause yellowing. Succulent plant leaves frequently shrivel and yellow as a result of a lack of water. Other stressors, such as fast temperature swings or poor soil quality, can also induce yellow foliage.

How do you repot Euphorbia Milii?

Crown of thorns prefers rich soil with good drainage. A good soil for your Euphorbia milii can be made by combining one part perlite (for drainage) and two parts organic potting soil (no additional fertilizer).

Plants that are potted in the incorrect combination will thrive at first, but will eventually succumb to root rot caused by increased water retention in the soil.

Re-potting your crown of thorns plant every two years in the spring is beneficial to its health. In general, a clean pot of the next size up with fresh soil is sufficient because slightly tight circumstances promote flowering.

Wear gloves and move the plant cautiously so that you don’t break off the stems or injure yourself with the thorns or sap. (Some gardeners safeguard their hands by holding the plant in a potholder.) Tightly pack the potting mixture around the roots.

Once the plant has reached full growth (approximately 2 feet tall for the species when maintained as a houseplant, but this may vary depending on variations and cultivars), you can replace just a small amount of the surface soil with a fresh potting mixture each year to improve soil texture and nutrition.
