Euphorbia cotinifolia Propagation: Key Points and Precautions Explained
Euphorbia cotinifolia is native to Mexico and Guatemala. It is an evergreen shrub or small shrub. Because its leaves are red all year round, it is very suitable for ornamental use, whether in pots or in gardens. Artificial propagation of Euphorbia cotinifolia can be done by two methods: cuttings and sowing.
Euphorbia cotinifolia
1. Cuttings propagation is best done in early summer. Cut healthy, mature branches. The cuttings should be 10-15 cm long. Let the white latex flowing from the cut end of the branch dry slightly, then insert them into a propagation sand bed. Keep the sand bed moist and the environment at 22-25°C. Roots usually form in 15-20 days. When the roots grow to 5-6 cm, plant them in pots.
2. Sowing propagation can be carried out immediately after the seeds are harvested, otherwise the seeds easily lose their germination ability. Evenly scatter the seeds into a moist sand bed and keep the bed temperature at 25-30°C. They will germinate in about 1 month. When the seedlings grow to 10 cm, they can be transplanted.
How to Grow Euphorbia cotinifolia: Key Points for Propagating Euphorbia cotinifolia
Euphorbia cotinifolia, also known as "African red," has thin leaves, broadly elliptic to nearly round, red to purplish red, with terminal panicles. Its ornamental effect is quite good. So what are the cultivation methods for Euphorbia cotinifolia? How should it be propagated? Let's learn about it together below.
I. How to Grow Euphorbia cotinifolia
The potting medium for Euphorbia cotinifolia can be prepared by mixing cultivated soil, peat soil and coarse sand. Do not water too much during the growing season, to avoid water accumulation in the pot. When the temperature drops in autumn and winter, watering should be strictly controlled. If the potting soil is too wet, it easily causes leaf drop and may even lead to root and stem rot. During the growing season, fertilize once every half month, and additionally apply 2-3 phosphorus and potassium fertilizers, to keep the plant lush with branches and leaves and prevent excessive leggy growth.
During the growing season, Euphorbia cotinifolia prefers a sunny environment, but in summer it must be shaded to avoid direct strong light. During cultivation, move it as little as possible, so as not to break branches and leaves and cause latex to flow out. The suitable growing temperature is 18-24°C from April to September, and 13-18°C from September to April of the following year. The overwintering temperature should not be lower than 10°C, otherwise the leaves easily change color and fall off.
Euphorbia cotinifolia tolerates pruning well and has strong branching ability. In the overwintering season, the leaf color easily fades or the leaves turn yellow and fall off. Combined with repotting in spring, shape and prune the plant, remove dead branches, lower the plant shape, and encourage more branching. At the same time, Euphorbia cotinifolia grows relatively fast in summer. If the plant is too tall, pinch it back appropriately to keep the plant full and attractive.
