Feeding method of holly stump
1. Watering: Holly pile likes semi-cloudy and humid environment. Keep the basin soil moist at ordinary times. Need to be watered in time during flowering and fruiting. When the temperature is dry in summer, you can water it in the morning and evening, spray a proper amount of water and keep it moist. The temperature is low in winter, so it is necessary to control watering and keep the soil slightly dry. 2. Fertilization: Apply sufficient organic fertilizer to the holly mound before winter. During the growing period, apply thin organic fertilizer once every half month. Fertilization should be based on organic fertilizer containing nitrogen, phosphorus and potassium. Potassium dihydrogen phosphate solution can be sprayed at flowering stage to promote fruit growth. 3. Lighting: Holly should not always be kept indoors for viewing. It needs certain lighting conditions. You can move indoors to bask in the sun. It is also necessary to prune branches and leaves that are too dense and hinder fruit viewing, and increase ventilation and light transmission, which is conducive to plant growth. 4. Soil use: The downhill pile of Ilex cornuta has wide adaptability to soil, but it is not tolerant to saline-alkali soil. It is best to use fertile and well-drained acidic soil. If the soil is not suitable, the cultivated Ilex cornuta will grow poorly. 4. Soil replacement: change the soil every 2-3 years, usually in February-March in spring. When changing soil, you can prune some withered and rotten roots, or apply some base fertilizer to promote root growth. 5. Pests and diseases: Holly mound has strong adaptability to the environment and few pests and diseases, mainly including psyllid, scale insect, red spider, moth larva, aphid and bituminous coal disease. It needs to be sprayed in time for prevention and control.
Planting management of Cornus officinalis hill piles
1. temperature: Qingshan pile likes warm environment in winter, and the suitable growth temperature is 15-20 degrees. When the temperature is above 35 degrees in summer, it is necessary to shade and cool down. If the temperature drops in winter, you need to move indoors for maintenance. 2. Humidity: I am drought-tolerant. I like humidity, but I'm afraid of stagnant water. Usually water should be done without watering, but it should be watered thoroughly. When the soil is dry, you can water it once instead of frequently. The soil should not be too dry or too wet. 3. Nutrition: The growth of Ilex cornuta cannot be separated from the supply of nutrition. Nitrogen fertilizer is topdressing once a month in the growing period, and phosphorus and potassium fertilizer are topdressing mainly in the flowering and fruiting period. At this time, it is necessary to control the application of nitrogen fertilizer so as not to affect the results. 4. Pruning: The downhill pile of Ilex cornuta grows fast and needs pruning. In the process of seedling growth, it is necessary to carry out coring treatment, which can promote the growth of lateral branches, maintain a good tree shape, maintain ventilation and light transmission, and reduce the occurrence of pests and diseases.
