The best soil selected for potted Saxifraga is sandy soil rich in organic matter, and it also has good drainage. It can be mixed with self-made culture soil and river sand.
Temperature: the most suitable growth temperature is between 15 ℃ ~ 25 ℃, and it is also cold resistant, and can winter at 5 ℃.
However, the flower and Leaf Varieties of T. tricolor are not cold resistant. The overwintering temperature is 15 ℃. If it is lower than this temperature, it will die. Therefore, it is necessary to keep warm in winter.
Light: if there is not enough light, the color of the leaves will be dimmed. In summer, indoor shade is also required to avoid direct sunlight. Keep the room temperature above 5 ℃ in winter. It is located near the south window in the room where the sun is abundant.
Watering: during the growing period, a large amount of water is needed to make the pot soil fully wet, but the flower pot cannot be immersed in the water. In the two weeks after flowering, the amount of water should be reduced gradually. When the plant enters the dormancy state, as long as the basin soil is not dry.
During the growing period, the basin soil should be kept moist, and the leaves are easy to wither due to a little drought. At the same time, the basin water should be prevented, or the roots will rot.
Fertilization: the fertilizer should be applied under the leaves of Saxifraga, so as not to contaminate the leaves and affect the plant growth. In the vigorous growth period in spring, nitrogen fertilizer is applied every 20 days, and no fertilizer is applied in high temperature in summer and low temperature in winter.
Saxifraga can be propagated by sowing and dividing plants. Sowing was carried out from March to April, all the year round, but spring and autumn were the best.
Saxifraga likes to loose and ventilate soil, and the hardened soil is easy to dim the color of leaves. Therefore, the basin should be changed every other year in early spring.
The main diseases are grey mould and powdery mildew.
The pest may be mealybug and whitefly.
In daily maintenance, we should always pay attention to observation, keep alert, and keep the beautiful Saxifraga, just like protecting the beautiful love.
