Temperature Requirements
Euphorbia hararensis is a hardy plant that can withstand high temperatures. The plant can grow in temperatures ranging from 60°F to 100°F. However, it is essential to avoid exposing the plant to temperatures below 50°F.
Soil Requirements
Euphorbia hararensis prefers well-draining soil. The plant requires soil with good aeration and should not be waterlogged. The plant can grow in various soil types, including sandy soils, loamy soils, and clay soils. However, adding organic matter to the soil can improve its fertility and drainage capacity.
Cultivation Methods
Euphorbia hararensis Pax thrives best in well-draining soil. It prefers sandy loam soil with a pH range of 6 to 8. It requires partial shade, but it can also tolerate full sun. Plant the Euphorbia hararensis Pax in a pot or the ground, but be cautious when transplanting. Wear gloves and ensure that the roots are not damaged during the process.
Watering Needs
Euphorbia hararensis Pax is drought-tolerant and does not require frequent watering. Water it thoroughly only when the soil has become completely dry. Overwatering can lead to root rot, which is fatal to this plant. During the winter season, water even less frequently to prevent the roots from becoming too moist and rotting.
Fertilization
When fertilizing Euphorbia hararensis Pax, provide it with a balanced fertilizer once every month during the growing season, which typically occurs in the spring and summer months. Refrain from fertilizing during the winter season, as growth slows considerably. Applying too much fertilizer can cause the plant to grow too quickly, which may lead to weak and spindly branches.
Pruning
Pruning Euphorbia hararensis Pax is essential for its health and appearance. Wear gloves and protective clothing when pruning this plant, as its sap can cause skin irritation. Prune back any dead or damaged branches with pruning shears or scissors. To maintain its size or shape, pinch it back selectively.

Propagation of Euphorbia hararensis Pax
Propagation of Euphorbia hararensis Pax can be done through the following methods:
Seeds
Euphorbia hararensis Pax can be propagated using seeds. Collect the seeds when they are matured and sown in a propagating mix. The seeds should be planted in well-draining soil and kept moist until they germinate. This method is the most reliable way to obtain a new plant, and it can produce many plants at once.
Cuttings
Cuttings can also be used to propagate Euphorbia hararensis Pax. Use a sharp, sterilized knife or scissors to take stem cuttings. Cut the stems at least two inches long and place them in a well-draining potting mix. Keep the soil moist but not wet and make sure the pot has adequate drainage. The cuttings should develop roots and start to grow within a few weeks.
Division
Another way to propagate Euphorbia hararensis Pax is through division. This method is best in the early spring when new growth is just starting to appear. Gently remove the existing plant from its pot and root ball, and then divide the root ball into sections. Each section should have a healthy portion of roots and shoots. Replant each section into an appropriately sized container with fresh soil. Make sure the soil is well-draining and provide adequate water and light to the newly propagated plants.
Air layering
Air layering is another propagation method for Euphorbia hararensis Pax. Make a small cut in a stem and wrap it with moist sphagnum moss, then cover it with plastic wrap. After a few weeks, roots will start to grow from the cut). Once enough roots have formed, cut the stem below the roots and pot the new plant in well-draining soil.
