Growing Euphorbia: How I Propagated My Euphorbia

Euphorbias are commonly known as "spurges." They have become popular as indoor houseplants due to their small size, varied color and texture, and exceptional tolerance of neglect. In the past they were usually grown in hanging baskets or terrariums. Propagating them is relatively simple once you know how.

Euphorbia, also known as Spurge, are easy-to-grow perennials. They may be indoor plants or part of your backyard. Euphorbia develops slowly but is not hard to take care of once mature.

If you plan to grow Euphorbia in your home or garden, find out how to propagate Euphorbia now to increase your chances of success. Euphorbia is one of the largest species of succulent plants in the world, with roughly 7,500 species.

You can propagate Spurge through offsets, seeds, or cuttings. The simplest and fastest way is with cuttings. If you have successful Spurge in your garden, you may want to consider taking cuttings and spreading them. Before taking cuttings, there are a few basic things you should note that are listed below:

Safety

Wear gloves to propagate Euphorbia. Remember to wear eye protection to prevent the plant’s toxic white latex sap from getting in contact with your eyes. Manipulate the plant and its cuttings with several layers of newsprint.

The Ideal Time to Get Cuttings

Cuttings are preferable in spring before the flower buds emerge, but summer is also favorable. However, cuttings done in fall or winter have little time to root, and cuttings should therefore only be used in emergencies to save plants suffering from root rot.

How Should You Get the Cuttings?

To cut, cut the stem of a mature Euphorbia plant. First, cut a healthy, spotless stem from your Euphorbia plant about 5 to 7 inches long. Then, use a clean razor blade or sharpened knife to reduce the scars on the parent plant.

Control of Sap Flow

Keep the cut-off tip under cold running water to contain the flow of white sap. Sprinkle the mother plant with cold water till the juice stops oozing. Short exposure to a candle flame or match may also inhibit the flow.

Dry Your Cutting

One of the main cultivation tips for Euphorbia is to let the cutting dry a few days before planting. Drying enables the sap to form a callus on the cut end and prevents decay. Place the cut on a paper towel in a warm, dry place with good air circulation to thoroughly dry for 3 to 7 days. Leave it out of direct sunlight.

Propagation Medium for Euphorbia

Use a well-drained medium such as perlite, a commercial cactus blend, or a 1:1 mix of sand and peat moss. Apply ½” coarse gravel to the medium surface to keep the cut upright.

Care For Euphorbia Following Propagation

Place the cutting in a hot, well-lit area away from direct sunlight. Keep the temperature between 65 and 75 degrees Fahrenheit. Your Euphorbia should take root about two months from now, while you should notice new growth.

Transplantation of Newly Propagated Euphorbia

Once the cuttings are rooted, you can transplant them into a large container. The propagated Euphorbia plant will require further care until it settles into its new home. Water carefully to evenly moisten the soil surface when dry to the touch during the growth season.

Let the Euphorbia dry out between waterings and not water more than once a week. Water slightly during the winter to barely moisten the soil’s surface is dried, but not more than once every other week. Do not water to the point that the ground is soggy or wet.

Sunlight Requirements

Place the succulent in a warm sunny spot where it will receive at least six hours of full sun each day. You can place it in a dry and airy room on a sunny windowsill or in a sunny place outside in the lush garden. The plant grows best at temperatures greater than 55 degrees F. Don’t let it freeze.

Propagation by Stem Cuttings

The spread of Euphorbias from cuttings is the easiest and fastest method for many species and reshapes an old plant. Collect cuttings from the plant in the spring before the flower buds appear.

Avoid taking euphorbia cuttings in autumn or winter because they will not have time to develop an adequate root system. In addition, the milky sap that comes out of Euphorbia is irritating to the skin. Wear gardening gloves thick enough to prevent spurge thorns from sticking to your skin.

Take cuttings with a sharp and clean knife. Remove multiple leaves from the underside of each cutting. Next, remove a 3-inch piece from the end of a spurge stalk with a sharp knife. Place the severed tip of the stem in a container of lukewarm water until the milky sap stops flowing. Remove the cutting from the water and let it dry for 3-4 days.

Immerse the injured tip of the cutting in a rooting hormone that contains a fungicide. Ensure the tip is well covered, and be careful not to breathe in the rooting hormone. Next, stick the lower end of each cutting in a pot filled with potting mixture and water. Cuttings should take root in 2 weeks.

Take cuttings of branched species at the point of branching. Single plants can be decapitated to encourage the production of lateral shoots, which can then be removed and rooted. Spurge leaves with large leaves should be removed with a knife just above the cut.

Place an even mixture of peat moss, coarse sand, and perlite into a small pot. The blend should be well-draining. Place the lower third of the stem in the soil mixture. Firmly stamp the soil around it to keep the cut in place and remove the air pockets.

Rooting may take longer than expected, but you can accelerate it by increasing the soil temperature to approximately 77 Fahrenheit using a thermostatically controlled heating mat. Avoid direct sunlight. If unrooted cuttings become dehydrated, you can save them by dipping them in water at room temperature until they swell again and replant them.

Add a little water to moisten the soil. Check the cut every day and add enough water to moisten the soil. Place the freshly planted cutting in a bright and cozy place in your house. The root system will grow over the next 20-30 days.

Propagation by Leaf Cuttings

Propagate Euphorbia using cuttings in spring. Ensure you wear gloves to protect yourself against sap. Delicately extract the leaves from the plants and place them in stone wool cubes, placed on coarse sand on a shelf.

Placing them in rock wool cubes will enhance the chances of euphorbia survival. Next, dip the leaves in a powder of rooting hormone to encourage growth and the development of new roots.

Place your rock wool with spurges on a tray lined with thick, damp sand. Cover the plant with a plastic cap to help increase the moisture your Euphorbia will need. The roots of your euphorbia plants should begin to grow in about a month.

Do not place leafy spurge cuttings under the sun. Hormonal rooting powder and fungicide help in this process. The plants will be mature enough at the end of 40 days, and you can pot them at this point.

Propagation by Seed

Another way of propagating your Euphorbia is through the propagation of seeds. The likelihood of success when propagating from seeds is lower than when you grow them from cuttings. The germination phase may take about 3-6 months during propagation from seeds, so please be patient in the process. While Euphorbia may be grown from seeds, they may be difficult to germinate.

Collect the seeds and soak them for 12 hours, change the water and then soak them for a further 12 hours. Let the seeds dry out naturally. Sow the seeds in an area that is well-drained, sandy, and sunny. Sow the seeds in an even mixture of coarse sand and commercial seed crop mix in the spring. Gently cover each seed with soil, rinse and wait it out.

Sprouting takes 2-6 months in cold weather, but heat can happen in 1-2 weeks. Press each seed . 9 cm into the ground, at a fair distance from each other. Gently irrigate and leave soil moist. Seed-borne transmission of Euphorbia can take up to two years before growth occurs.

Propagating Through Offsets

Offsets are an easy and efficient way to spread Euphorbia plants as long as healthy plants are available for cuttings. To propagate Euphorbia with offsets, find an offset that grows well. Then, cut approximately 2 inches below offset with pruners or clippers.

Give the offset time to be insensitive for another few days before insertion into the soil. The offsets will take root within approximately six weeks under appropriate conditions. Once they are rooted, you can transplant them into their original pot or move them to larger pots if required. To summarize propagation by offsets, proceed as follows:

● Let the plant expand and divide naturally.

● Be careful when detaching the offset from the mother plant to avoid damaging the roots or stems.

● Let the new offset dry at least one day before planting its roots and shoots pointing downwards in well-drained soil.

● Water sparingly until the grafts are rooted, at which time they can be transplanted outdoors or in jars.

Bottom Line

Euphorbia plants offer an excellent array of colors with their bracts of flowers. In addition, Euphorbia is easy to spread and maintain, making it an ideal choice for any gardener. Under the right conditions, you can quickly cultivate and spread Euphorbia in your garden.
