Desert rose (scientific name: Adenium obesum) is a succulent plant of the genus Desert Rose in the oleander family, also known as desert rose, desert rose, desert rose tree, etc. Native to the arid regions of Africa and the Arabian Peninsula, it can survive in extreme environments and is highly drought resistant.
The stems of desert roses are spherical or cylindrical, up to 30 centimeters in diameter and up to 2 meters in height. The stem stores a lot of water inside the stem, which can provide the plant with what it needs to grow during dry times. The surface of the stem has a gray or brown cortex with many small spines that prevent water evaporation and animal nibbling.
The leaves of the desert rose are oblong in shape with serrated edges, up to 15 cm in length and up to 5 cm in width. The leaves are green or dark green, shiny, thick in texture, and have fine hairs on the surface, which can reduce water loss. The leaves generally grow in spring and summer and fall in autumn and winter to adapt to arid climates.
The flowers of the desert rose are funnel-shaped, up to 5 centimeters in diameter, and come in a variety of colors such as red, pink, white, yellow, purple, and some have spots or stripes. The flowers generally bloom in spring and summer, and the flowering period lasts for several months, and the floral fragrance is very beautiful, resembling roses, hence the name.
The fruit of the desert rose is oblong in shape and can reach a length of up to 15 cm and a width of up to 1 cm. The inside of the fruit has many flat seeds with white hairs at both ends that can be spread by the wind.
The desert rose is a plant with high ornamental value, not only with bright flowers and peculiar stems, but also can be used as a potted plant or garden plant to decorate the home or public place.
Although desert roses are native to arid environments, they can be grown at home as long as you pay attention to the following:
Desert roses prefer well-breathable, well-drained, moderately fertile soils, rather than moist, sticky, acidic soils. Therefore, you can choose materials such as sand, perlite, vermiculite, etc., or buy specialized succulent soil to grow desert roses.
Before planting desert roses, spread the soil loosely and evenly on the bottom of the pot with a thickness of about 5 cm, then dig a small pit in the middle, put the roots of the desert roses in, and gently compact them so that they are in good contact with the soil, but not too compact, so as not to affect ventilation and drainage.
Desert roses prefer locations with plenty of light, good ventilation, and a suitable temperature, rather than dark, sultry, and cold locations. Therefore, you can choose places such as balconies, windowsills, or bright corners of the room to place desert roses.
Before placing a desert rose, consider the intensity and timing of the light, in general, the desert rose needs at least 6 hours of adequate light per day to keep the stems robust and the flowers vibrant. However, avoid direct sunlight as well, especially during the summer months, as this can cause burns to the leaves and flowers. Desert roses can be appropriately shaded or moved to adjust the intensity and timing of the light.
Before placing desert roses, consider ventilation, and in general, desert roses need to have good air circulation to keep the soil dry and the plants healthy. However, it is also important to avoid strong winds, especially in winter, which can cause the leaves and flowers to fall. Windows can be opened or fans can be used appropriately to regulate the ventilation situation.
Before placing desert roses, it is important to consider the temperature situation, generally speaking, the temperature range that desert roses adapt to is 15 35, too high or too low will affect the growth and flowering of the plant. However, it is also important to pay attention to changes in temperature differences, especially in spring and autumn, as this can lead to dormancy or leaf loss of plants. Heating or air conditioning can be used appropriately to regulate the temperature.
Desert rose is a drought-tolerant succulent plant that does not need to be watered frequently, and too much water can cause the plant to rot or die. Therefore, the frequency and amount of watering should be adjusted according to the season and climate.
Before watering, observe the moisture of the soil, and in general, watering is only required if the soil is completely dry. You can use your finger to feel the moisture in the soil, or stick a stick into the soil to see if it is wet to determine if it needs to be watered.
When watering, use warm or tap water, and avoid cold or mineral water, so as not to affect the absorption and metabolism of plants. Water evenly so that the soil is moist, but do not overwater to avoid water accumulation or soaking. Pay attention to the watering time, generally in the morning or evening, avoid watering at noon or evening, so as not to cause temperature difference or mold breeding.
In terms of the frequency of watering, it is necessary to make appropriate adjustments according to the season and climate. Generally speaking, spring and summer are the growing seasons of desert roses, which require more water and can be watered once a week. Autumn and winter are the dormant period for desert roses, which require less water and can be watered once a month. However, it is also necessary to flexibly adjust the frequency of watering according to the actual temperature and humidity to avoid being too rigid.
Desert rose is a moderately fertile plant that does not require frequent fertilization, and too much fertilizer can cause the plant to grow too fast or bloom too little. Therefore, the frequency and amount of fertilization should be adjusted according to the season and growth conditions.
Before fertilizing, it is necessary to observe the growth of the plant, and in general, fertilization is only required if the plant is growing slowly or has few flowering. You can judge whether fertilization is needed by looking at the thickness of the stem, the color of the leaves, and the number of flowers.
When fertilizing, use liquid fertilizers and avoid solid fertilizers so as not to clog the pores of the soil or burn the roots of the plants. It is necessary to choose fertilizers suitable for succulents, such as nitrogen, phosphorus, potassium, etc., to promote the growth and flowering of plants. To dilute the fertilizer, mix the fertilizer with water in the ratio of the instructions and pour it on the roots of the plant, avoiding pouring it on the stems or leaves of the plant to avoid spots or wilting.
In terms of the frequency of fertilization, it is necessary to make appropriate adjustments according to the season and growth conditions. Generally speaking, spring and summer are the growing season of desert roses, which require more fertilizer and can be fertilized once a month. Autumn and winter are the dormant period for desert roses, which require less fertilizer and can be fertilized once a quarter. However, it is also necessary to flexibly adjust the frequency of fertilization according to the actual temperature and humidity to avoid being too rigid.
Although desert rose is a pest-resistant plant, when planting at home, it is also necessary to pay attention to the prevention and control of common pests and diseases, such as aphids, powdery mildew, root rot, etc., and treat the damaged parts in time to maintain the health of the plant.
Before controlling pests and diseases, it is necessary to observe the appearance of the plant, and in general, it is necessary to control pests and diseases only if the plant is abnormal. You can judge whether there are pests or diseases by observing the color of the stems, the shape of the leaves, and the condition of the flowers.
When controlling pests and diseases, it is necessary to use appropriate methods and avoid using excessively strong or toxic agents to avoid harming plants or human bodies. According to different pests and diseases, choose different methods, such as the following:
Aphids: Aphids are a common pest that sucks the sap of plants, causing them to shrivel or deform. The control methods are: rinsing the plants with water to remove aphids;Spray the plant with soapy water or alcohol to kill aphids;Spray the plants with garlic juice or chili water to repel aphids;Spray the plant with tobacco water or chrysanthemum water to prevent the regeneration of aphids.
Powdery mildew: Powdery mildew is a common fungal disease that forms a white powder on the stems or leaves of plants, causing stunted growth or reduced flowering. The control methods are: washing the plant with water and removing the white powder;Spray the plant with sulfur or lime to kill the fungus;Spray the plant with lactic acid bacteria or yeast water to enhance the plant's resistance;Spray the plant with ginger or garlic water to inhibit the growth of the fungus.
Root rot: Root rot is a common bacterial disease that forms black or brown rot on the roots of plants, causing wilting or death of plants. The control methods are: soaking the plant with water to remove the rotten roots;Water the plants with disinfectant or high-temperature water to kill bacteria;Sprinkle charcoal or lime powder on the roots of the plant to prevent the spread of rot;Water the plants with ginger water or garlic water to inhibit the growth of bacteria.
In terms of the frequency of pest control, it is necessary to make appropriate adjustments according to the appearance of the plant and the changes in the environment. In general, the condition of the plant is observed once a week to detect and deal with signs of pests and diseases in time. However, it is also necessary to flexibly adjust the frequency of pest control according to the actual temperature and humidity, and avoid being too frequent or too random.
The desert rose is a beautiful and drought-tolerant succulent plant that can be grown at home, as long as you pay attention to the following:
