To make boxwood trees grow vigorously, attention should be paid to the following aspects: 1. Soil selection and management
Soil requirements: Poplar trees do not have strict soil requirements, but loose, fertile, and well drained sandy loam soil is preferred. When potting, vermiculite, peat soil, etc. can be used in combination to improve soil permeability and fertility.
Soil management: Regularly plow the soil to ensure it is loose and conducive to root growth. At the same time, a certain amount of base fertilizer can be added to provide sufficient nutrients for the growth of boxwood trees. 2、 Lighting and temperature control
Light requirements: boxwood trees are tolerant to shade and prefer light, and can grow well under general indoor and outdoor conditions. However, in long-term shaded environments, it is easy to cause branches to grow excessively long or weaken. Adequate light should be provided. In the morning, it can be placed in a sunny place, and in the afternoon, it can be moved to a cool place and exposed to half a day of light.
Temperature control: Poplar trees are heat-resistant and cold resistant, able to withstand summer sun exposure and extreme cold of around minus 20 degrees Celsius. But during high temperatures and humidity in summer, more ventilation and light should be provided to reduce temperature and minimize the occurrence of pests and diseases. 3、 Watering and Fertilization
Watering management: Poplar trees prefer moisture, but avoid long-term waterlogging. Proper watering should be carried out according to the weather and soil moisture to keep the soil moist but not too wet. During the dry season, it is important to maintain moderate watering, but not too much, to prevent the roots from maturing.
Fertilization management: Fertilization should mainly be organic fertilizer or compound fertilizer, applied once a year in spring and autumn. Apply germination promoting fertilizer in spring, heat-resistant fertilizer in summer (if the growth is vigorous in summer, it can be omitted), strong wood fertilizer in autumn, and insulation fertilizer in winter. When fertilizing, the fertilizer should be fully matured and deeply buried in the planting hole to avoid burning the roots. 4、 Pruning and trimming
Pruning timing: Poplar trees should be pruned in spring and autumn to maintain their beautiful appearance and lush density.
Trimming method: Use sharp tools for trimming and disinfect after each trimming to prevent the spread of diseases. Pruning should be done according to the growth and desired shape of the boxwood tree to maintain its healthy and beautiful state. 5、 Disease and pest control
Common diseases: Poplar trees may encounter diseases such as anthracnose and leaf spot, which can be controlled by spraying with zinc solution.
Common pests: The main pests include scale insects, moths, aphids, etc., which can be killed with pesticides such as fenitrothion and imidacloprid.
Prevention and control measures: Regularly observe the growth of boxwood trees, and take timely prevention and control measures when diseases and pests are discovered. Pesticides or biopesticides can be used for spraying, but attention should be paid to the usage method and concentration to avoid causing harm to plants.
Through reasonable soil management, light and temperature control, watering and fertilization, pruning and trimming, as well as pest and disease control measures, boxwood trees can grow more lush and healthy.
