Sowing methods and Management points of Desert Rose

Desert rose can also be called "silly sister". It would be wrong if you think it is called desert rose. In fact, desert rose is an out-and-out succulent plant. At present, more than 15000 varieties have been registered, and it is one of the most diverse plants in the world. Needless to say, today the editor will briefly talk about the sowing methods and management points of desert rose.

I. characteristics of desert roses

1. Appearance features: simple leaves alternate, Obovate, 8-10cm long, 2-4cm wide, dark green on the ventral side, gray-green on the back, flowers trumpet-shaped, Corolla 5-lobed with rose, pink, white and complex color, seeds with white pilose.

two。 Desert rose propagation: sowing propagation, cutting propagation, striping propagation, grafting and so on, generally use sowing method to propagate, culture period radish head as small as the rhizome, and then in the growing season with different varieties and colors of branches grafted on the same plant, greatly improve the ornamental of flowers.

Second, the sowing method of desert rose

1. Selection of matrix and utensils

Matrix: choose loose and breathable fine sand or coconut bran, or special soil for planting succulent plants. The substrate should be disinfected before sowing, and it can be heated at high temperature or disinfected with potassium permanganate.

Sowing utensils: the use of hole plates, if it is home farming, you can choose ordinary flowerpots on it.

two。 Seed placement and soil covering

Put the long seeds horizontally on the substrate and cover the thin substrate once. The thickness is appropriate to cover the seeds. Too thick will affect the budding rate.

3. Watering and seedling pot placement

Water thoroughly when watering for the first time, and the basin filled with soil can also be put into the soaking basin to ensure that the water can be felt on the surface of the basin soil.

After sowing, it should be placed in a cool, ventilated place where scattered light can be seen to avoid direct light.

4. Germination and moisturizing

After the seeds germinate properly spray water, generally 3-7 days later the buds will break through the soil one after another, this is the need to spray water every 2-3 days.

III. Key points of management

1. The cultivation of desert roses should ensure sufficient light, ensure ventilation, keep the soil dry, pay attention to ventilation and heat preservation, and prevent frostbite.

2. It is necessary to change the basin once a year and apply appropriate long-term base fertilizer when changing the basin, such as mature bean cake, bone meal and so on.

3. When yellow leaves appear in desert roses, watering should be controlled immediately, fertilization should be suspended and placed in places with plenty of light.

4. it should be noted that the whole desert rose plant is poisonous, so do not use it and do not put it in a place where children can touch it.

Desert rose pot key points Desert Rose likes dry, sunny environment, drought resistance but not moisture resistance, heat resistance but not cold resistance. The suitable temperature for growth is 20-30 ℃. When family cultivation, it is appropriate to place a place with sufficient sunlight or scattered light, and it is appropriate to use a rich calcium-rich sandy loam with fertile, loose and well-drained sand loam. Its florescence is from May to December, and the flowers are red, rose, pink, white and so on. It is easy to bear fruit in greenhouse cultivation in the south. To keep desert roses well, you should pay attention to the following points: don't think that seemingly delicate desert roses cannot accept strong sunlight. In fact, a good sunny environment helps desert roses blossom. In addition to the peak growth period, even in the dormant period, desert roses still need plenty of sunlight to survive the winter. Temperature desert rose likes to grow in a high temperature and ventilated environment, but in the southern summer, that is, the growing period of desert rose, the average temperature is about 30 ℃, which makes it very suitable for growing in the south; in winter, due to the poor cold resistance of desert rose, it is appropriate to move into indoor cultivation and keep dry, so that desert rose can bloom that beautiful flower again in spring and summer. Watered desert roses should be grown in a moist environment. Even during the growth period, there should not be too much water, and before each watering, it must be made sure that the surface of the basin soil is completely dry. Do not water the plant during the dormant period, as it will only make the plant more vulnerable to cold injury and wither. Fertilization the annual spring and summer rainy season is the growing period of desert roses, so fertilizers should be added slightly at this time to make up for the nutrients consumed during their growth. However, due to the growth rate of desert roses, slow-acting fertilizer is better, such as mature compost and so on. As for autumn and winter is the dormant period of desert roses, their growth is very slow or even stop, so do not fertilize during this period. Basin soil and desert roses like other succulent plants like sandy soil with good drainage, therefore, when changing pots, it is best to add more river sand or small gravel to the general soil, which can improve the drainage of basin soil. generally, it is needed only when the plant has grown quite luxuriantly. On the other hand, desert roses at seedling stage should be changed every year. The method of changing the basin is very simple: first, stop watering before changing the basin, and then after the basin soil is completely dry, you can pour out the plant, remove the old basin soil and trim the roots, and then plant it again. It should be dry rather than wet during the growing period. During the high temperature period in summer, the topsoil can be watered after drying according to the soil condition. Generally watered once every 3 days, the basin can not accumulate water, otherwise the root is easy to rot. The compound fertilizer containing calcium and phosphorus can be applied twice before flowering when nitrogen fertilizer is applied for 2 or 3 times in the vigorous growth season in spring every year. In the dry season in winter, the plant enters a dormant period. If the temperature is lower than 10 ℃, the leaves should be fallen, and watering should be controlled to keep the soil dry. Introduction and maintenance of Desert Rose

Desert rose (Tianbao flower, Adan flower)

The suitable growth temperature is above 18 ℃, and the lowest overwintering temperature should be above 10 ℃. Like plenty of sunshine, can be moved to the outdoor sun for cultivation in summer. Strong growing plants change pots every 2 to 3 years.
