Cultivation and pruning of Euphorbia milii

Speaking of Euphorbia pulcherrima, many flower lovers like it very much. It is a plant of the Cactaceae family. It is not only very easy to grow, but also has large and beautiful flowers, just like blooming lotus. The color is even brighter than the lotus. It has always been loved by people. Let’s talk about the cultivation and pruning methods of Euphorbia pulcherrima.

1. Preparation of potting soil. Flower pots have great limitations. The flower pot for cultivating Euphorbia obesa is a special small environment. No matter what kind of soil is used alone, it cannot meet the various needs of the potted Euphorbia obesa for soil. Therefore, the required potting soil must be prepared before potting. The potting soil can be purchased from a flower store or prepared by yourself. The potting soil for cultivating Euphorbia obesa requires looseness, good drainage and water retention. It should be combined with appropriate culture soil according to the requirements of Euphorbia obesa. It is usually made of 40% leaf mold, 30% garden soil, 20% compost, and 10% sand. Add bone meal or hoof pieces as base fertilizer. After the potting soil is prepared, it is best to sterilize it at high temperature before use, or it can be exposed to the sun for sterilization.

2. Planting in the pot: First put broken tiles at the bottom of the pot, then fill it with culture soil, place the Euphorbia lathyris plant upright in the center of the pot with the roots stretched out. Fill the soil to half of the pot, then lift and shake the Euphorbia lathyris plant gently to compact the culture soil. Do not plant too deep, just keep the rhizome level with the pot mouth. If the depth is too shallow, it will affect the survival; if it is too deep, it will affect the growth of the Euphorbia after transplantation. Water thoroughly once after planting. After planting, keep it in a shaded environment for about a week. After the root system recovers, move it to a sunny place and manage it according to normal methods.

3. Water management: Keep the soil in the pot slightly moist during the growing period, and water it when the soil is dry. If the soil in the pot is too dry or too wet, it will easily cause buds and flowers to fall off. Avoid water accumulation in the pot. Pour out the water in the pot after rain, otherwise the roots will easily rot. In the hot summer, water the plants frequently to maintain air humidity. If you water too often and in too much water, it will easily cause the Euphorbia lathyris plant to grow too tall, making it difficult for the Euphorbia lathyris to bud and bloom. Therefore, you should water in moderation and keep the soil from being too dry. Keep the soil in the pot slightly moist during the growing period, and water it when the soil is dry. If the soil in the pot is too dry or too wet, it will easily cause buds and flowers to fall off. Avoid water accumulation in the pot. Pour out the water in the pot after rain, otherwise the roots will easily rot. In the hot summer, water the plants frequently to maintain air humidity.

4. Fertilization management: Control the amount of nitrogen fertilizer applied. If too much nitrogen fertilizer is applied and phosphorus and potassium fertilizers are insufficient, it will easily cause the Euphorbia lathyris plants to grow too tall and it will be difficult for the Euphorbia lathyris to bud and bloom. Instead, it will not bloom or will bloom very little. Therefore, avoid using excessive nitrogen fertilizer, especially control the use of chemical fertilizers. Generally, apply light, decomposed cake fertilizer water. Do not apply fertilizer too frequently, apply an appropriate amount, especially adding phosphorus and potassium fertilizers during the bud formation period. Generally, apply thin, decomposed cake fertilizer water once every half a month. Apply bone meal or superphosphate 1-2 times during the bud stage, or spray 0.2% potassium dihydrogen phosphate.

5. Wipe off the excessively sprouted thin lateral buds and leaf-like stems sprouting from the base in time, remove the remaining flowers and old leaf-like stems that have bloomed in time when the flowers wither, and set up a circular support in time, and evenly tie the stems and leaves of the Euphorbia obesa to the circular support to facilitate ventilation.

6. Place it in a place with sufficient scattered light and good ventilation. Excessive shading will affect flowering, often causing the Euphorbia oblonga plant to grow too tall and not bloom or bloom very little. However, if exposed to strong direct sunlight, the leaf-like stems will wither and the skin will develop burns and ulcers. Therefore, the Euphorbia obesa must be placed in a place with sufficient scattered light and good ventilation. In addition to appropriate shade in the hot summer season, it should be exposed to the sun as much as possible.

7. Move it indoors before the Descent of Frost and maintain the temperature at 10-15℃. The Euphorbia obesa is native to the tropical regions of America. It likes a warm, humid environment with plenty of sunlight and good ventilation. It is drought-resistant but not cold-resistant.

8. Supplementary fertilizer : The growth of the Euphorbia milii is large and it consumes a lot of nutrients. The soil in the pot will become more and more compacted, and the original nutrients in the soil in the pot have been basically consumed. In order not to affect the growth, development and flowering of the Euphorbia milii, it is necessary to supplement the base fertilizer. Generally, part of the old soil in which the nutrients have been almost consumed is replaced, and decomposed cake fertilizer is applied to meet the nutrient needs of the growth and flowering of the Euphorbia milii. Repot every 2-3 years in spring or autumn.

9. Loosen the soil after it dries slightly each time you water or fertilize.

The Euphorbia pulcherrima is deeply loved by people for its delicate and light posture, bright colors and rich fragrance. It is mainly used for potted viewing, and a variety of combinations are used in the greenhouse to enhance the viewing effect.
