The planting method and Propagation of Flowers-Desert Rose

Desert rose, also known as Tianbao flower, oleander family, etc., Tianbao flower is a succulent plant, also known as succulent plant. Succulent shrubs or small trees, up to 4.5 m; trunk swollen. Next, we will introduce the breeding methods and precautions of desert roses. Let's take a look.

Culture methods of Desert Rose

First, desert roses are mainly propagated by sowing and cutting. It is better to sow in spring, and the method of spot sowing is used to facilitate the management after emergence. Be sure to disinfect the substrate before sowing. After emergence, pay attention to the substrate in the sowing plate should not be too wet, otherwise the roots may rot and cause a large number of seedlings to die. It is better to cut in the vigorous growing season. Cut the branch into about 10 cm, soak the lower end in water and dilute the mucus at the cut to prevent cementation from affecting the hairy root. It can be inserted into the sand bed or directly into the sterilized cultivation substrate, and it can take root in about 15-30 days. In reproduction, it is recommended to use sowing method to propagate, so that the plant rhizome can naturally expand to form a good plant shape. Cutting seedlings can not, but also greatly reduce the ornamental value.

Second, in addition, in the cultivation, the desert rose branches are easy to grow, which affects the beautiful plant shape, so the plant shape can be changed by grafting. All the branches can be cut off according to a certain shape at a certain height of the plant, and then the upper end of the cut branches can be grafted by split grafting. The plant shape of the grafted plant is beautiful, and the flower branches are compact and ornamental after flowering.

Third, desert roses are more resistant to drought, not too much water each time, if more water, it is easy to cause root rot, at the same time, the branches are too long, it is more troublesome to prune. When it is hot in summer, it can be watered according to the soil condition. It is usually watered once every two or three days, and no water can be accumulated in the basin. As the temperature drops in winter, desert roses also enter a semi-dormant period, so properly control watering, keep the soil dry and water once a week. Proper drought is very beneficial to the growth of desert roses. The leaves of winter desert roses fall off gradually when they enter the dormant period, which is normal, so there is no need to be nervous about it. ]

Fourth, desert roses prefer phosphorus and potassium fertilizer, which is usually replenished once a month or so. During the peak growth period in summer, sufficient fertilizer and water are needed so that the flowers can be luxuriant and bright. In addition, combined with the annual basin change, you can also properly apply some long-term base fertilizer in the basin, such as rotten bean cake, bone meal and so on.

Fifth, the pruning of desert roses is also very important. If you do not pay attention to the usual pruning and let it grow, it is easy to lose its ornamental value. After flowering is the best time for pruning, you can make a choice according to your personal preference. Note: if you have more branches, you will blossom more. If you want to get more flowers, you must find ways to keep more ramets.

Matters needing attention in desert rose culture

1. The leaf spot disease of desert rose is serious, which can cause a large number of leaves to fall off. It can be controlled with 25% carbendazim wettable powder and 50% topiramate 1000 times.

2. The main pest of desert rose is shell insect. When it is serious, it will cause all the leaves to fall off, plant growth point necrosis, and even plant death. Family cultivation should pay attention to observation, as soon as found that immediately with a cotton swab dipped in water to erase it. It can also be sprayed twice with 40% omethoate EC 1000-2000 times or 50% fenitrothion EC 1000 times during the spawning and incubation period. [attention should be paid to the safety of drug use when carrying out pest control. ]

3. Methods of reproduction

Cutting propagation is usually carried out in spring and summer. Select 1-2-year-old branches, the top branch is the best, cut into about 10 cm long. The stems of desert roses have transparent milk (note that the milk is poisonous). Wash off the milk with clean water and place it in a cool and ventilated place to let the incision heal and then insert it. The matrix can use clean river sand or soil, pay attention to drainage and ventilation. During the cutting period, we should pay attention to control the watering times, keep the soil moist and shade properly. It can take root 3-4 weeks after insertion.

The desert rose which is propagated by air striping has a higher survival rate and a relatively simple operation. In general, striping can be carried out in the growing season of the plant, especially in spring and summer. When pressing the strip, first cut or peel it around with a sharp knife where you want to take root, then wrap the wound with water moss or soil, then wrap the matrix with a transparent film and tie it tightly at both ends. After seeing the roots grow to the thin film, they can be cut off and planted.

Grafting to avoid the rainy season, after grafting in spring, you will soon be able to enjoy the flowers. The length of scion is generally 7-10 cm. After grafting, put the pot plant in a shaded place for maintenance. If successful, the wound can be healed in about 10 days, and then placed in a sunny place. If the film banding is released in about 2 months, the constriction will occur too late and the subsequent growth will be affected. Grafting can graft different varieties on the same plant and improve the ornamental value.

Sowing desert roses is not easy to bear fruit and artificial pollination is needed. The fruit will crack naturally after a certain period of time, and the seeds are easy to spread, so it is necessary to harvest before cracking. Because the seeds are sown as soon as possible after harvest, they should also be stored in a cool and dry place, otherwise they will easily lose their growth ability.

The reason for the yellowing of desert rose leaves

1. Shortly after buying, it is in the period of adaptation, and a small amount of yellow leaves are normal and common.

2. The flowerpot is airtight and the root is small, so as to avoid the long-term dampness of the pot soil and cause root rot.

3. When the temperature is low, winter will be in a dormant period, that is, the leaves turn yellow and fall off, or even fall into poles.

4. It is relatively resistant to drought, and the amount of water should not be too much each time. If there is more water, it is easy to cause root rot and cause leaf yellow.

5, the sun is too shady, but also remember not to expose to the sun, the leaves are also easy to yellowing, and affect flowering.

6. poor ventilation and insufficient light will inevitably lead to yellow leaves, and in serious cases, the whole plant will rot and die.

7. If you apply too much fertilizer, you should apply an appropriate amount of fertilizer, not more.

8. There are earthworms or golden needle worms (red spiders, beetles) and other pests in the basin soil, and there will also be leaf yellow symptoms.

9, the harm of leaf spot and root rot, when the leaf spot is serious, it can cause a large number of leaves to fall off.

Finally, it is necessary to pay special attention to: whether it is in the adaptation period or dormant period, watering should be controlled and fertilization should be suspended. When a large number of new buds are sprouted in spring, topdressing is added according to the growth situation. Winter can be placed in a sunny position, and keep the basin soil dry, the lowest temperature should not be lower than 8 ℃. Other seasons can be placed in the sun area, not in the shade to maintain, otherwise even if watering, fertilization is normal will be due to less light and yellow leaves fall off.

When do desert roses blossom?

First of all, it is stated that desert roses need a certain age to bloom, and they are too young to blossom.

1. If the desert rose already has buds but does not open at this time, it is lack of fertilizer (light fat water can be used instead of clear water for each watering, but the flower bud color needs to be stopped), the ambient temperature is too low (it is recommended to raise to 15: 25 ℃), and the light is insufficient (it needs to be put in an adequate place).

2. If the desert rose does not have buds at this time, the tree is too young, or it does not grow enough branches after new pruning!

3. Besides, the flower bud differentiation of desert rose needs reasonable watering, fertilization, light and temperature in daily management.

The above are the desert rose culture methods and precautions introduced to you by Xiaobian. I hope I can help you.
