What type of soil is best for desert rose
This article introduces the best soil for desert roses and the optimal soil mixing methods for planting green plants and flowers. The detailed introduction is as follows.
The desert rose is a succulent plant of the Apocynaceae family, native to the tropical and subtropical regions south of the Sahara in Africa. They prefer a warm and dry environment all year round, and in temperate regions, they can only be grown as indoor potted plants or landscapes.
The desert rose is a particularly drought-resistant and heat-tolerant succulent plant that can grow into a shrub shape. The leaves will fall when the temperature is too low. The base of the main stem of the desert rose is slightly swollen. The leaves grow in a spiral pattern upward, similar to the leaves of oleanders.
Now there are many horticultural varieties of desert roses, in addition to the common single-petal varieties, there are also some double-petal varieties, with flower colors including common red, pink, white, purple, and various mixed colors.

In warm places all year round, especially in tropical regions, desert roses can bloom throughout the year, while in northern or subtropical regions, they generally bloom in summer and autumn.
Tip:
Before caring for desert roses, it is important to note that both the stems and leaves of the plant are toxic. Avoid ingesting the sap from the branches and be sure to wash your hands after pruning or planting.
1. Light
If you want to grow desert roses well, make sure to place them in a location with plenty of sunlight, with at least 6-8 hours of direct sunlight per day. In the summer, when it is excessively hot, if your desert rose is not yet robust, you should provide some shade in the first and second years, especially when the temperature exceeds 40 degrees Celsius.

2. Temperature
Desert roses are sensitive to cold and prefer warm environments. The minimum temperature for maintenance in winter should be above 10 degrees Celsius (if the temperature drops below 4 degrees Celsius, they will be frostbitten), with the best growth temperature between 20-33 degrees Celsius.
Desert roses can tolerate high temperatures and can be exposed to the sun in temperatures over 40 degrees Celsius, but for newly purchased plants, it is important to provide some shade during the afternoon in the first two years.
3. Watering
When caring for potted desert roses, avoid waterlogging and do not let the potting soil remain moist all the time. This must be matched with suitable potting soil according to local climate conditions. If it rains a lot, add more granular soil to the soil, such as mixing with granular soil, peat soil, and perlite in a ratio of 5:3:2. Granular soil can be made from common materials like red jade soil, volcanic rock, wheat husk stone, or coal cinder.
If this seems too麻烦, you can mix granular soil and peat soil in a 1:1 ratio, choosing two or three different substrates for the granular soil, and note to use larger particle peat soil.
4. Potting
Desert roses are a rare plant that is suitable for purchasing in the summer. Even in the hot summer, you can buy bare-root seedlings or potted seedlings. If you buy a bare-root desert rose, check for pests and diseases after receiving it, remove withered roots, let the wounded parts dry in a well-ventilated, shaded area, plant them in a smaller pot, and do not rush to water them. Wait a few days before providing water.
