1, soil matrix
Red plum has strong adaptability to cultivated soil, but it is suggested to choose mixed soil with loose soil, ventilation and drainage and sufficient nutrients for cultivation. Mix humus soil, sandy loam soil, garden soil and other materials, sterilize at high temperature and fill them in the soil for later use.
2. Sufficient illumination Hongmei likes to grow under the conditions of warmth, brightness, sufficient illumination and sufficient water, and the average daily illumination duration should be guaranteed to be more than 6 to 7 hours. For direct sunlight in summer, it is necessary to cover the leaves properly to avoid sunburn. In winter, the light is weak, and red berries can enjoy direct light at noon.
3. Water irrigation
When watering red plums, the principle of seeing dry and wet should be guaranteed, which can be adjusted according to the changes of different seasons and climatic conditions. Water every 1~3 days during the growing period. In summer, the evaporation of water is too large. In addition to watering, plants can also be sprayed with water mist in winter to increase humidity, reduce moisture and avoid freezing injury.
4. Fertilization should be carried out in the vigorous growth period of red plum, and diluted cake fertilizer water solution should be applied every 20~30 days. Because of the temperature change, the growth rate of red plum slows down, and the frequency of fertilization should also be reduced to avoid burning roots. No matter what kind of fertilizer, it should be diluted before irrigation.
5. Preventive measures
Every 2~3 years, we should change pots and soil for red plum to ensure the soil health and adapt to the growth needs of red plum. Prune red berries during dormancy or flowering, and remove broken flowers, long branches and leaves, dead branches and rotten leaves. And do a good job of plastic surgery to ensure the high-quality ornamental of red plum.
