Culture methods and matters needing attention of Desert Rose in potted Flower Plant

Desert roses are shaped like trumpets, rosy red and very beautiful. Umbels are clumps of brilliant flowers that blossom throughout the year. The desert rose is named because its origin is close to the desert and as red as a rose. Desert rose simple leaves alternate, Obovate, tip acute, 8 cm ~ 10 cm long, 2 cm ~ 4 cm wide, leathery, glossy, dark green ventral, grayish green abaxially, entire. Raceme, terminal, with more than 10 flowers, trumpet-shaped, 6 cm ~ 8 cm long; Corolla 5-lobed, with rose, pink, white and complex colors. The flowering period of desert rose 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. The seeds are white pilose, which can help them spread in flight.

Potted plants need plenty of sunshine and good drainage. The mixed soil of fertile, loose sand and rotten leaf soil is the best. During the growing period, it should be dry rather than wet, and the high temperature in summer should be watered once a day, usually every 2-3 days. Fertilize 2-3 times in the whole year. The leaves fall normally during the dormant period of drought in winter. To plant or change pots in spring. Can be planted in the south and overwintered outdoors.

It should be potted in the north and overwintered indoors. Potted soil can be mixed with rotten leaf soil and coarse sand, followed by a small amount of rotten dried bone powder. Put some broken tiles into the bottom of the pot before planting to facilitate drainage. Change the basin and replace the new culture soil every spring. The newly planted and newly changed plants can be maintained indoors or in the shade, less watering, and enter into normal management after slow seedling. During the growing period, it should be placed in a sunny place outdoors, or it can be cultivated in a greenhouse. Sufficient light is needed. Need to enter the house in winter, shelter in the sun, if you put it in the greenhouse, it is better to grow it. In winter, the indoor temperature is more than 12 ℃. If the basin soil is dry, it can survive the winter safely under the temperature of 7-8 ℃.

Spring and autumn are the exuberant growth period, which should be fully watered to keep the basin soil moist, but not too wet. Water should be dry and wet, dry and thoroughly watered. The temperature is relatively low in early spring and late autumn, so watering should be controlled. Watering is reduced in winter, and the basin soil remains dry, but it should also be watered if it is too dry. Do not need much fertilizer, apply dilute liquid fertilizer 1-2 times a month during the growing period, and stop fertilizing in winter.

Desert roses, like other succulent plants, like sandy soil with good drainage, so when changing the basin, it is best to add more river sand or small gravel to the general soil, so as to improve the drainage of the 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.

Commonly used cutting, grafting and striping propagation, can also be sown. Cuttings, best in summer, select 1-2-year-old branches, the top branches are the best, cut into 10 cm long, wait for the incision to dry and then put them in the sand bed, and take root about 3-4 weeks after cutting. Grafting, using oleander as rootstock, split grafting method in summer, after survival, the plant grows healthily and blossoms easily. Striping, often using the high-altitude striping method in summer, cut off 2 big 3 on the sturdy branches, first filled with moss and then bandaged with plastic film, rooting for about 25 days, and cut off the potted plant 45 days later. Sowing in summer, the germination temperature is 21 ℃.
