How To Propagate Euphorbia Milii

The unusual houseplant known as the crown of thorns, which is native to Madagascar, was introduced to Americans. These plants can bloom at any time of the year as long as they experience both dry and rainy periods. When obtaining crown of thorn cuttings, it is a good idea to use gloves because their stems and leaves contain a latex sap that some gardeners could be sensitive to. Spring and summer, when the plant is actively growing, are the greatest seasons for cuttings.

To avoid unnecessary harm and disease transmission to the parent plant, use a razor blade or very sharp knife that is clean. Make a straight cut 3 to 4 inches (7.5 cm) long across the tip of a leaf. To stop latex sap from dripping from the parent’s cut end, spritz it with cold water.

The following stage is crucial for cutting-based crown of thorns propagation. Allow the cut end to callus by laying the cuttings on newspaper in a cool, dry location. When you place the cutting into soil, this encourages cells that could develop into roots and helps avoid rot. The end will typically seem puckered and grayish white after a few days.

How to Propagate Crown of Thorns Cuttings

Cuttings make crown of thorns propagation considerably simpler than seed does. If conditions aren’t quite right, seed may not even germinate at all, taking months to do so. Cuttings require a good medium made of damp peat and sand in equal amounts. For a speedier, fuller impact, place many cuttings in a container that is 4 to 5 inches (10-12.5 cm) in diameter.

The cutting should only be standing up when the callused end is inserted into the medium and buried. Maintain a light mist of moisture on the medium, but refrain from using a saucer or too much water. Plants frequently begin to bloom soon after the 12- to 14-week period during which they are rooted.

Can crown of thorns be rooted in water?

Rooting the cutting in water is another way to propagate crown-of-thorns. Put the cutting in a tall, narrow glass that has 1 inch of water at the bottom. The cutting will begin to take root in two weeks or less if you keep it in bright, indirect sunshine. After the cutting develops roots, plant it in a soil mix made especially for cacti and succulents.

Can Euphorbia be grown from a cutting?

By taking cuttings in the spring and summer, you can grow extra euphorbia plants; just be sure to use waterproof gloves when doing so. Select unflowered growing tips around 15cm long. Cut the leaves in half, remove the bottom two-thirds, and then mix the remaining portion in a glass of cold water to remove the milky sap.

Is it possible to grow Euphorbia in water?

A succulent euphorbia called Euphorbia trigona is grown for its ornamental stems. If it is rooted in water, it will rot and should not be. Take a stem cutting of this plant in late spring or early summer to propagate it.

When taking cuttings, keep your skin and eyes protected because the sap might irritate some people’s skin or eyes or perhaps create an allergic response. The health of the parent plant and the cutting depends on stopping the flow of milky sap. Spray water onto the parent’s wound after dipping the cutting end in water. To prevent infection, allow the cutting to “heal” (dry out) for a few days. Create a container with a peat moss base that has been wet, add perlite for enhanced drainage, and then top it with a layer of horticultural sand or vermiculite to avoid rot. Place the cutting in the potting mixture and keep it at room temperature in filtered light.

For around two months, keep the potting material just slightly damp. By that time, the cutting will have developed roots and new growth. The plant can be replanted in a succulent potting mix and cared for as an adult euphorbia.

Do crown of thorns require direct sunlight?

For the best blooms, place crown of thorns euphorbia bushes in full sun. The plants can withstand salt spray as well. A crown of thorns plant needs irrigation after transplanting until its root system becomes established, just like any shrub. After that, you can use less water because of its high tolerance for drought.

It’s simple to grow extra crown of thorns from tip cuttings if you enjoy having them in your garden. Just be sure to keep it away from freezing and frost. Crown of thorns can be multiplied from cuttings of the tips. But before you try this, put on some heavy-duty gloves. Both the milky fluid and the spines might irritate your skin.

How long does it take for Euphorbia cuttings to root?

When the right conditions are present, the majority of the evergreen euphorbia species will self-sow. Young seedlings can be pulled off the plant. Like other perennials, the non-evergreen varieties can be divided in the early spring or the early fall. These procedures can also be used to successfully develop evergreen and woody species from cuttings.


Portion Euphrobia that have a permanent framework of branches will require deadheading after flowering, or if the entire stem that was flowering starts to die back, you can clip out some of the branches at the base. A good dome of brief, unflowered stems or shoots will remain, and they’ll bloom the next year. E. characias subsp. wulfenii and E. myrsinites are two examples.

E. amygdaloides var. robbiae is an evergreen groundcover that can be deadheaded in the summer to tidy up clumps by shearing off spent flower stems.


Mulching borders is a great strategy to prevent weed growth and water evaporation. For typical garden growing conditions, this could be done with organic materials; however, if growing the silvery and grey species in a Mediterranean planting scheme, this might be done with gravel.

See our section on Deadheading in Ongoing Care above for more information on how pruning is typically done. Herbaceous plants, however, will die back throughout the winter, so you can tidy up the plant by removing any old, brown, or dead-looking stems.

These are multiplied through division. As you’ll do this right after flowering, it will happen in late spring for the earliest blossoming. The optimum time to divide anything that blooms later in the summer is in the spring when plants are just starting to grow.

Softwood cuttings are used to reproduce these shrubby-appearing euphorbias, especially the ones that grow stems one year and bloom the following year. In the early spring, use the young, short shoots at the base. E. characias and its relatives, E. myrsinites, and E. mellifera are excellent choices.

Although cultivars cannot be grown from seed and the seedlings will have somewhat different behaviors and colors, species can be grown from seed. When capsules become brown, gather the seed.

Euphorbia reproduce in what ways?

The family Euphorbiaceae includes the genus Euphorbia. It is commonly recognized that this genus is one of the most varied in the entire plant kingdom, with approximately 2000 species. Euphorbias can range in size from weed-like, low-growing “spurges to magnificent, cactus-like succulents that can reach heights of several meters. One well-known species in this genus is the Poinsetta (E. pulcherrima), a stunning and well-liked houseplant.

The distribution of Euphorbia includes tropical regions of Africa (where the majority of the succulent Euphorbias are found), Madagascar, and the Americas as well as colder, temperate regions of Asia and Europe. Australia and the Pacific Islands both have euphorbia species.

When cut open, the majority of euphorbia species release a milky latex sap. This functions as both a defense mechanism to stop animals from eating the plant and a natural wound-healing mechanism for the plant. If it comes into touch with skin, it can result in excruciating inflammation and a rash. If consumed, some species’ latex can be quite harmful to people. The toxicities of several species are listed in this helpful resource.

This toxin has a di- or tri-terpene ester chemical structure, depending on the species. The distinctive feature that sets all euphorbia species apart from cacti is their milky sap.

A business in Australia is presently investigating the use of E. peplus sap as a skin cancer treatment. According to the notion, the sap kills the cancerous skin cells and forms a scab that finally falls off.

Due to the diversity of the genus Euphorbia, numerous reproductive strategies are seen. Monoecious plants have blooms on the same plant that are both male and female. Some Euphorbias have male and female blooms on separate plants, or they are dioecious.

This genus was given that name by Carolus Linnaeus in honor of the Greek physician Euphorbus, who is credited with discovering a use for Euphorbia as a medicine (most likely Resin Spurge).

This succulent is also a euphorbia. Take note of how the spines protrude in pairs, similar to the species seen to the right.

This Euphorbia has thick, protective skin and spines. As opposed to a cactus, the spines protrude in pairs.

How are Euphorbia Milii maintained?

One of the first indoor plants is the continuously blooming Crown of Thorns (Euphorbia milii). With a few exceptions, it requires little maintenance and has a wide range of varieties so that your home always looks cheerfully multicolored.

How is a Crown of Thorns plant cared for? Give your crown of thorns plant warm, direct sunlight, temperatures between 65 and 90 °F (18 and 32 °C), low humidity, and sandy soil that drains quickly. Water when the top inch of soil is dry, prune to keep the form, and fertilize sparingly every two to three weeks with a low-nitrogen fertilizer.

Although it is obvious from the spine-studded stems that it prefers cactus-like circumstances, some unique ways assist make the most of this venerable plant. Although caution must be used when handling, you can enjoy one of the best set-and-forget houseplants ever by following safety precautions and using these growing suggestions.

Why isn’t the crown of thorns blooming on mine?

  • Crown-of-thorns plants are extremely reactive to moisture and temperature. Absence of bloom is the first sign of a sudden cool or wet spell. Growers with experience advise constant attention and perseverance.
  • Like all members of the Euphorbia family, the milky sap of the crown-of-thorns is extremely irritating to skin and should be regarded as harmful to children and dogs. Around children and animals, the plant should be considered harmful in all parts.

How quickly does Euphorbia expand?

The heavier stems have a tendency to point in the direction of the light as they grow. To stop the container from leaning, rotate it.

The shedding of leaves is typical. In a few months, fresh leaves will emerge at the top of the stem.

I can get up to 30 feet tall in nature. I can grow quickly indoors in a container and reach a height of 5-8 feet. From the base, fresh, light-green shoots will emerge.

You may have overwatered if you notice rotting at the plant’s base or notice that the stems are no longer spongey. By removing the top treatment and allowing the soil to breathe, you might attempt to dry it out. If the stem is still too wet, you can cut it with a fresh corrugated knife and transplant it in fresh, drier soil.

When ought I to trim my Euphorbia?

Trim away any winter damage as soon as spring arrives. In order to prevent disease and pest infestation, it is a recommended grooming practice to remove dead and broken stems from the plant’s base. Some cultivars require the removal of all old growth at the base as they die to the ground each winter in order to reappear from the roots.

Only the tips of stems that sprouted the previous year are where the majority of euphorbia species bloom. Throughout the spring and summer, trim back euphorbia stems to their base right after bloom to ensure that the plant doesn’t become overloaded and produces flowers on a regular basis. Use clean hand pruners to cut off a blossoming stem at the base as it begins to turn yellow, and then compost the clippings. Pinch the tips of kinds that have a tendency to become lanky and flop over as they get taller when new stems emerge. Shorter stems are the consequence, which are better able to support blooms.
