Introduction of Euphorbia paniculata

Euphorbia pulcherrima is a plant of the Cactaceae family. It has a flat, lanceolate stem and water-lily-like flowers. The plant is about 50 to 100 cm tall. It is generally propagated by cuttings, which can be done in the greenhouse all year round, but it is best to do it from May to July.

Cultivation method of Euphorbia pulcherrima

The Euphorbia obesa prefers a warm and humid environment with good air circulation and sufficient light. It cannot tolerate exposure to strong sunlight and needs shade in the summer. At normal times, the soil only needs to be kept moist, and no water accumulation should occur. It likes fertile, loose, slightly acidic calcareous sandy soil or loam that is rich in organic matter.

Watering method

The Euphorbia pulcherrima prefers slightly acidic or neutral water. It can be irrigated with rainwater and unpolluted river or lake water. If tap water is used, it needs to be left to stand for 1-2 days in advance. It should be watered more during the bud formation period from March to April. During the flowering period from May to July, control watering and water it thoroughly once a week. It is better to keep the soil slightly dry after flowering. After October, water it sparingly.

Fertilization method

When planting Euphorbia obesa, you can apply decomposed base fertilizer. Fertilize once every 15 days during the growth period. Fertilization should be carried out in the morning or evening on a sunny day, and stop fertilizing during the dormant period.

Pruning methods

Plant the Euphorbia obesa in a flowerpot with a diameter of 30 cm, and keep 20 to 25 stems. When it grows to a certain height, you can trim off the stems that germinate too late or fail to reach the required height at one time due to poor growth or slow growth. After the flowering period, trim off the withered flowers and old and weak branches.

Things to note when growing Euphorbia paniculata

If the Euphorbia pulex is not properly maintained, it will often suffer from stem rot, brown spot disease and root-knot nematodes. It can be sprayed with carbendazim and the root-knot nematodes can be controlled with dibromochloropropane emulsifiable concentrate. If ventilation is not good, it will be susceptible to aphids, scale insects and red spiders, which can be killed by spraying with carbendazim emulsifiable concentrate.
