How to care for desert roses? How to care for desert roses?

Desert Rose Origin and Habits: Native to Kenya, Africa. It prefers high temperatures, dryness and sunny conditions. Resistant to heat, not cold-tolerant, drought-resistant, avoid water and moisture. It is advisable to use calcium-rich, well-lined sandy loam soil. Winter temperatures are not lower than 10.

Propagation: Propagation by cuttings, grafting and pressure is commonly used. Cuttings, the best in summer, select 1-2 years old branches, the top branch is the best, cut to 10 cm long, after the incision is dry, insert it in the sand bed, and take root about 3 to 4 weeks after cutting.

Grafting, using oleander as rootstock, in the summer using the splitting method, after the plant grows robust and easy to flower. Stripping, often in summer, using the high-altitude stripping method, cut off 2 3 on the strong branches, first fill with moss and then wrap with plastic film, about 25 days to take root, 45 days after cutting the potted plant.

Cultivation: Potted plants need to be sunny and well-drained. A mixture of fertile, loose sand and humus soil is best.

The growing period should be dry rather than wet, and the high temperature in summer should be watered once a day, and usually watered once every 2-3 days. Fertilize 2-3 times after the whole process. Normal defoliation during the dormant period of winter drought.

Pests and diseases: sometimes there is a leaf spot damage, which can be sprayed with 500 times of 50% Tobuzin wettable powder. The insect pests are caused by scale insects and heartworms, and they are sprayed with 1000 times of 50% pine borer emulsifiable concentrate.

Application: The desert rose plant is short, the tree shape is simple and vigorous, and the rhizome is as hypertrophied as a wine bottle. It blooms twice a year from April to May and from September to October, and is bright red and beautiful, resembling a trumpet, which is extremely chic and deeply loved by people.

The small courtyard is planted in the south, which is simple and dignified, natural and generous. Potted ornamental, decorating the interior and balcony in a unique style.

The desert rose is an exotic plant that can cause catastrophic damage to the local ecology because it has no natural predators, so don't throw it away if you don't want to keep it.

After buying it, put it in a cool place for 2 days and water it thoroughly. You haven't recovered from what you're doing now.

1. Plenty of sunshine.

In the process of maintaining desert roses, the giving of light is a very important factor, if the light is insufficient, it will cause the plant to be thin and weak, and the roots are relatively small, not too large. When raising seedlings, you can give 6 hours of sunlight every day, but the seedlings can not be exposed to the sun, and you need to be properly shaded and avoid direct light.

2. Control watering.

Desert roses do not require much water, so they should be watered well, which can help the growth of the plant and promote the expansion of the roots. Usually wait until the soil is dry before watering, one-time watering to water thoroughly, must not appear a large amount of water, otherwise not only is not conducive to root expansion, but will lead to root rot.

3. Reasonable fertilization.

If you don't apply fertilizer for a long time, if you don't have enough nutrients, it will be difficult for the seedlings to grow, and the roots will not be able to expand. At the seedling stage, nitrogen fertilizer can be applied appropriately to promote the growth and development of seedlings. However, it should be noted that thick fertilizer should not be applied, and thin liquid fertilizer should be appropriately applied. Bika water-soluble fertilizer can be selected.

Fourth, suitable soil.

Suitable soil is the basis for promoting growth, and loose and fertile sandy soil should be provided to provide good basic conditions for growth.

5. Proper pruning.

Plants have a tip advantage, so in order to control the height of the plant, promote the overall growth and root expansion, it should be pruned properly.

Desert roses are native to East Africa and were introduced to China in the 80s of the last century.

Desert roses prefer to grow in a hot and sunny environment, and prefer to grow in a loose, breathable, well-drained environment.

The reason why it is called desert rose is related to its growth habit of high temperature and drought resistance, summer is the growth period of desert roses, even if the temperature is as high as 30 degrees Celsius or more, desert roses can grow very well. In winter, if the temperature is too low, the desert roses should be moved to a room with a suitable temperature to prevent frostbite at low temperatures.

Watering: 1 time in about 3 days in spring and autumn, 1-2 days in summer, 1 time a week in winter, and no water in the potting soil. Fertilization:

In the growth period, more phosphorus and potassium fertilizers should be applied, less nitrogen fertilizers should be used, and phosphorus and potassium fertilizers should be used mainly during the growth and reproduction period, and nitrogen fertilizers should be stopped. Light: It should be kept in a sunny place, and proper shading is required in summer.

1. Watering should be less. Desert roses naturally prefer dry growing environments and are especially intolerant to moisture. Desert roses are usually watered, and this frequency should be maintained.

Desert roses are watered once every three days in spring and autumn, once every two days in summer, and once every seven days in winter. On the contrary, properly keeping the soil dry will be more conducive to the growth of desert roses.

2. The light should be sufficient. To cultivate desert roses, you must ensure sufficient sunlight, even in summer, desert roses do not need to be shaded, and receiving strong light in the sun will not have much effect. Desert roses, if not exposed to sunlight for a long time, will make its branches grow particularly vigorous, but they are very thin, and the verdant leaves are easy to yellow, affecting flowering.

3. Proper fertilization. Due to the particularly long flowering period of desert roses, the consumption of nutrients is still very large, and we should also supplement some fertilizers, preferably with liquid fertilizer to promote the absorption of roots. In addition, in the peak season of desert roses, fertilizer should be applied once every half a month or so, and fertilizer should be stopped in winter.

4. Prune the plant type. If we want to make the overall plant of the desert rose more beautiful, we need to prune, and the desert rose is not like some other bonsai plants, it is easy to shape, because its vitality is more tenacious and vigorous, it is easy to have scattered branches. Pruning desert roses after they have grown is often a bit late, and the best time to prune is when they are young.

1. Soil requirements.

The soil of the desert rose requires loose and breathable, at that time, I taught everyone to use perlite, vermiculite, cinder, and peaty soil to configure, this desert rose requires good water permeability, so we want to use more than half of the granular soil, that is, half of the cinder, and half of the other nutrient soil.

2. Lighting requirements.

Desert roses can survive in strong sunlight, so it is important to keep them in a sunny place when cultivating them.

In addition, desert roses are afraid of cold, so they should be moved indoors for maintenance in winter, and it is best to get sunlight behind a window.

3. Watering requirements.

Desert roses prefer humid environments, but it is not advisable to overwater them, just keep the soil moist to avoid rotting the roots of the desert roses.

The principle of watering desert roses is to see dry and wet, try to water as little as possible, and do not over-dry, so as not to shrink the stems.

4. Ambient temperature.

Desert roses like to survive in warmer environments, so they can be sunbathed outside in the summer and indoors in the winter.

Conservation points.

Desert Rose. Desert roses prefer dry, sunny environments and are resistant to drought but not moisture, and hot but not cold. The growth temperature is 20-30. For home cultivation, it is advisable to place a place with sufficient sunlight or scattered light, and it is advisable to use fertile, loose and well-drained calcium-rich sandy loam soil.

5 December is its flowering period, and the flowers are red, rose, pink, white and other colors. Southern greenhouse cultivation is easier to set fruit. Sunshine Don't think that seemingly delicate desert roses can't tolerate strong sunlight, in fact, good sunshine can help desert roses bloom.

In addition to the vigorous growth period, the desert rose still needs plenty of sunlight to overwinter even during the dormant period. Temperature Desert roses like to grow in a high-temperature and ventilated environment, and in the summer of the south, that is, the growth period of the desert rose, the average temperature is around 30, making it very suitable for growing in the south; In winter, due to the poor cold tolerance of desert roses, it is advisable to move indoors and keep them dry so that they can bloom again in spring and summer. Watering Desert roses should be grown in a humid environment.

Even during the growing period, there should be no excessive water, and before each watering, make sure that the surface of the potting soil is completely dry. Do not water the plant during its dormant period, as this will only make the plant more susceptible to cold damage and wilting. Fertilization The spring and summer rainy seasons are the growing seasons for desert roses, so a little fertilizer should be added at this time to adequately the nutrients consumed during their growth.

However, due to the fast and slow growth rate of desert roses, it is better to use slow-acting fertilizers, such as well-rotted compost. As for autumn and winter, it is the dormant period of the desert rose, its growth is very slow or even stops, therefore, it is important not to fertilize during this time. Desert Rose.

Potting soil and repotting Desert roses, like other succulents, prefer sandy soil with good drainage, so when repotting, it is best to add more river sand or small gravel to the general soil, which can improve the drainage of the potting soil, which is generally only needed when the plant has grown quite lush. Desert roses at the seedling stage should be repotted every year. The method of repotting is very simple, first before changing the potting, stop watering, and then after the potting soil is completely dry, you can pour out the plants, remove the old potting soil and prune the root system, and then replant.

The growing period should be dry rather than wet. During the high temperature period in summer, the topsoil can be watered after drying according to the soil condition. Generally, water once every 3 days, and the pot can not accumulate water, otherwise the roots are easy to rot.

Apply nitrogen fertilizer 2 to 3 times in the spring growing season every year, and apply compound fertilizer containing calcium and phosphorus twice before flowering. During the dry winter season, the plants enter a dormant period. If the temperature is below 10, the leaves will fall, at which point watering should be controlled to keep the soil dry.

Desert roses like a high-temperature, dry, sunny growing environment, and prefer loose, breathable and fertile sandy soil. It likes plenty of sunlight to promote flowering, and it is generally no problem above 30 degrees. In winter, when it is below 10 degrees Celsius, it should be moved indoors in time.

1. Cultivation medium.

Desert rose likes loose and breathable, well-drained calcareous loam soil, and the cultivation substrate can be mixed with 4 parts of humus, 2 parts of vermiculite, 3 parts of coarse sand, and 1 part of limestone grains, and can only be used after high temperature disinfection in a steam boiler. Before use, an appropriate amount of ternary compound fertilizer is applied as base fertilizer, and it is best to choose slow-release compound fertilizer.

2. Illumination. Desert roses love the sun and should be well lit throughout the growing season. Due to the strong phototropism of plant growth, it should be repotted regularly, otherwise it is easy to cause the growth of branches to be bent, tilted, and scattered, which will reduce the aesthetics.

3. Temperature. Desert roses like high temperatures, dryness, and extreme heat, and grow at a suitable temperature of 25 35. It is not cold-tolerant, and the temperature in the greenhouse is kept above 15 in the northern winter, otherwise it is difficult to ensure its good plant shape, and it is very easy to fall leaves.

4. Fertilizer and water. Desert roses are drought tolerant, and watering should strictly grasp the principle of seeing dry and wet. Summer is the peak period for desert roses, so make sure you have enough water** and water them every 1 2 days. Desert roses do not like large fertilizer, nitrogen fertilizer is the main fertilizer during the growth period, supplemented by phosphorus and potassium fertilizer, the ratio is about 2 1 1, generally every 10 days to apply a thin compound liquid fertilizer.

5. Plastic surgery. Plastic surgery plays a key role in the commercialization of desert roses. Because desert roses have soft branches, poor natural branching force, and only have leaves in the growing areas of the branches, they are often cultivated by grafting to achieve the ideal plant size. In addition, pruning can also be done to shorten excessively long branches to promote branching, so that the plant has a fuller crown shape.

6. Seed harvesting.

Desert roses are self-flowering and sterile and need to be pollinated by hand. The fruit cracks on its own after ripening, and the seeds are easy to be lost, so it should be bagged before ripening, harvested in time, and dried in the shade before storage. Seeds should not be stored for a long time, generally not more than 3 months, otherwise the germination rate will be reduced.
