Culture methods and matters needing attention of Prunus mume

Potted soil: the leaves of tiger thorn plum grow upright and upward, and the flowerpot had better choose a deeper tube basin, which will appear compact and beautiful. The soil used for breeding can use two portions of garden soil and two portions of river sand, one part of compost, and a small amount of horseshoe bone powder as base fertilizer.

Temperature: the most suitable temperature for growth is 15 degrees to 32 degrees, more afraid of high temperature and muggy weather, if the summer temperature reaches more than 33 degrees will enter a dormant state. In winter, it is also necessary to strengthen the temperature management of Chimonanthus roxburghii, because when the temperature drops below 4 degrees Celsius, it will enter a dormant period, and when the temperature is close to 0 degrees, it will freeze to death.

Lighting: Chimonanthus przewalskii is suitable for curing in semi-shade, or shading it by 50% in the sun, which is conducive to the growth of its leaves and make its color more beautiful. Direct sunlight can be given in spring and autumn, because the temperature is not very high, keep it in a bright place indoors in winter and control the light in summer.

Fei Shui: the drought tolerance of Prunus angustifolia is very strong, and it is very suitable for growing in a dry environment.

Chimonanthus przewalskii likes warmth and is not resistant to cold. It grows best at about 22 ℃ in daytime and 15 ℃ at night. It keeps 15 ℃ to 20 ℃ in greenhouse and blossoms all the year round. If it falls to 10 ℃, the fallen leaves turn into semi-dormant state, reveal new leaves in the next spring and continue to blossom. Tiger thorn plum Xiguang, the more sufficient sunshine before the flower, the more bright flowers, long-lasting, lack of light, then the color is dim, long-term shade, then do not bloom. Attention should also be paid to maintaining good ventilation.

Chimonanthus przewalskii can use cultivated soil to pad hoof horn as base fertilizer, fertilize once every half a month during the growing period, stop fertilizing after autumn, avoid using fertilizer with oil to prevent root rot. Tiger thorn plum is resistant to drought, and watering in spring and autumn should be dry and wet. It can be watered once a day in summer, waterproof in rainy season, not dry or watered in winter, and should not be moist for a long time in the basin; water should also be controlled during flowering, which can easily lead to falling flowers and rotting roots.

If it is not pruned in time and let it grow naturally, the main branch will grow longer and longer, not only blossom less, but also the plant shape is not beautiful.

Propagation mode and cutting time

Cutting substrate is used for cutting nutrient soil or river sand, peat soil and other materials. Due to the limited conditions, it is difficult to get the ideal cutting substrate for family cutting. It is recommended to use a prepared and sterilized cutting substrate; medium and coarse river sand is also recommended, but rinse with clean water several times before use. Do not use sea sand and river sand in saline-alkali areas, they are not suitable for the growth of flowers and plants.

Prunus przewalskii is mainly propagated by cuttings. Cuttings can be cut throughout the growing period, but May-June is the best, with a high survival rate, and cuttings of Prunus mume are the most likely to survive. Select sturdy branches, about 10 cm to 15 cm long (with 3-4 leaf nodes), dry the white pulp from the cut, coat it with plant ash, and dry it in a cool place for 2 to 3 days, so that the wound is dried and then inserted into the plain sand, watered thoroughly, and then watered less. when the basin soil is slightly dry, it can take root after about 50 to 60 days.

3, bad air: the tiger thorn plum has certain requirements for the surrounding growth environment, which is most suitable for the place of ventilation and ventilation, so it is generally planted in the courtyard and balcony. If the indoor ventilation is not good and it is muggy, it will cause the leaves of tiger thorn plum to turn yellow.

4. Drug damage: when watering, the tap water should be hung for a few days, otherwise the chlorides in the water are toxic to the plants, causing the leaves to turn yellow and fall.

5. Winter dormancy: at the end of autumn, when the plum is in full bloom, it is also about to enter the winter dormancy period, so it is normal for leaves to turn yellow. Even if the leaves fall out, new leaves will sprout again in spring.

6. The temperature is too low: in the areas where the winter temperature is below 10 degrees, the old leaves will fall off, leaving only the top young leaves; when the temperature is lower, the leaves will all dry up and fall off.
