Culture method of potted Desert Rose

Some flower friends asked how to breed desert roses. Generally speaking, desert roses are easy to raise in summer and can be watered outdoors once a week. It is difficult to keep them dormant in season. Here are some of the author's experiences in breeding desert roses in recent years. I hope it can give you a reference.

1. Propagation: cuttings and striping are mainly used for propagation. Cutting is better in the vigorous growing season, cut the branches into about 10 cm, dip the lower end into water, dilute the mucus at the cut to prevent cementation and affect rooting, and insert it into the sterilized cultivation substrate after being stained with plant ash, which can take root in about 15-30 days. It is recommended to use sowing method during propagation, so that the rhizome of the plant can naturally expand to form a good plant shape, while the cuttings can not, which will greatly reduce the ornamental value. The method of high pressure is used in striping propagation, and the root system of high pressure method is strong and the survival rate is high. Can be carried out in the growing season, you can first cut or peel the strip with a sharp knife, then treat it with rooting powder, then wrap it with water moss and wrap it with film. If the water moss is short of water during high pressure, a syringe can be used to replenish the water, and it can be cut off from the mother body half a year later. I only propagate desert roses by cutting, but it doesn't work well. I suggest you don't bother. Desert rose cuttings have no thick roots and have low ornamental value.

2, basin soil: my basin soil is: blue stone or red brick grain, light stone, fairy soil or ordinary basin soil; the proportion is 1:1:1. Note: mix with an appropriate amount of slow-release fertilizer or fermented granular chicken manure, a little more at the bottom of the basin soil.

3. Sunshine: desert rose has thick roots and leathery leaves, indicating that it can accept strong sunlight, and good light helps desert roses blossom. It needs sunshine not only in the prosperous period, but also in the dormant period. There is plenty of sunshine in the desert of Beijing to survive the winter (dormant period). The environment with less sunlight is not suitable for farming.

4. Temperature: desert rose growing environment is high temperature and ventilation. Beijing generally in May temperature reached 25 ℃ or so, move the plant from indoor to outdoor, the average temperature is more than 30 ℃, do not grow like shade; desert rose cold tolerance is poor, after Beijing National Day holiday (the lowest temperature is less than 15 ℃), the plant should be moved indoors, and keep dry (basically cut off water) to ensure its dormancy, good dormancy desert rose can bloom in spring and summer.

5. Watering: the thick rhizomes of desert roses are most afraid of dampness, and the long-term dampness of basin soil is easy to cause root ulcers, resulting in plant death. Therefore, the principle of watering desert roses must be grasped. My experience is: Beijing winter 3 months must not water the basin, to keep the basin soil dry. Winter watering according to indoor dryness, you can spray water in the environment or water in the basin cushion plate (my practical method is to water the plate once a month or one and a half months, spray water at noon when the sun shines every week, and the basin soil surface should be wet). And when the plant enters the room from the outside, the leaves fall off quickly (almost bare). Don't be afraid, and don't water them, at least 15 days later. Beijing is the desert rose growing season (outdoor) from May to October, when the plant has just moved outside, when the outdoor temperature is low at night, do not water, you can spray some water when the sun is good. When the plant begins to produce leaves, it should be watered in winter. When the temperature reaches 30 ℃, it can be watered into the basin, but the water content should not be too much. Each watering should be made sure that the basin soil is completely dry before it can be carried out.

Recommended control method: in order to accurately grasp the dry and wet condition of the potted soil, I found a flowerpot the same size as planting desert roses, put the same soil and the same amount of soil, and watered the two pots with or without flowers. A week later, the soil in the flowerless pot is poured out to check the dry and wet conditions. if the pot soil is all dry, you can calculate your watering time every time, which means that you have no problem watering once a week.

6. Fertilization: Beijing is the growing period of desert roses from May to October every year, and the flowering period is at this time, fertilizer can be slightly added for its growth. Note: never apply raw fertilizer. Raw fertilizer is easy to cause rotten roots and pot worms.

7. Change the basin: the method is simple, when the flowers are moved outdoors every year, the drying is easy to operate. After replanting, do not water, should be placed in the semi-shade to slow the seedlings, to wait for the recovery of the leaves, in the watering through.

8. Pest control

Disease control: desert rose is mainly caused by leaf spot and root rot. When the leaf spot is serious, it can cause a large number of leaves to fall off. It can be controlled with 25% carbendazim wettable powder and 50% topiramate 1000 times. Root rot often causes root rot and death, which can be irrigated with 50% topiramine wet powder or 1000 times agricultural streptomycin.

Pest control: the main pest of desert rose is shell insect, which causes all leaves to fall off, plant growth point necrosis and even plant death when it occurs seriously. Once it is found that it is immediately wiped with water with cotton swabs, 40% omethoate EC 1000-2000 times or 50% fenitrothion EC 1000 times can be sprayed 1-2 times during the spawning and incubation period.
