Loosening soil and weeding
Shallow turn around the tree before winter, the depth is about 5-20CM, and it will be completely flat after the next spring. All kinds of malignant weeds (such as peanuts, sedges, etc.). ) Once discovered, it will be eradicated immediately.
Dressing and shaping
The main purpose of seedling pruning and shaping is to ensure the normal growth of seedlings and improve their ornamental value. Pruning of big trees, trees and shrubs mainly focuses on retaining natural tree shapes; Tree pruning mainly prunes long branches, pests and diseases, cross branches, drooping branches and dead branches; Shrub pruning is to promote its lush foliage, uniform distribution and flower bud formation, while hedges and spherical plants are mainly pruned. Pruning is generally carried out when the seedlings enter dormancy in autumn, and shaping is mainly carried out before the seedlings germinate in spring. Trim the lawn regularly (once in autumn and winter) and pay attention to picking grass frequently. If there is low-lying water, fill it and resurface it. The height of the grass should be controlled at about 5-6CM. If it exceeds the height, use a lawn mower to level off and trim the edge of the lawn once a month to keep the lines clear.
Fertilization and watering irrigation time should be controlled according to the change of weather. Before the rainy season (the maximum temperature is below 30 degrees Celsius), spray for 4 hours every morning and evening, and stop spraying from 10: 30 to 3: 00 in the morning. If it doesn't rain for a long time and the soil is dry (white and cracked), irrigation should be carried out in the morning or evening. Fertilization is an effective means to promote the growth and health of seedlings. Fertilization should be carried out after the roots of plants are damaged and begin to grow, that is, after the seedlings are planted for about half a year (lawn for three months), root fertilizers such as urea and compound fertilizer are generally applied. Foliage fertilizer can also be used for shrubs.

Pests and diseases are mainly controlled by big trees and small colored shrubs. Because the roots and branches of big trees are seriously damaged after transplanting, the natural recovery period is long, and the function of resisting pests and diseases is reduced, so we should pay close attention to the big trees, and once the symptoms of pests and diseases appear, we should immediately prescribe the right medicine to prevent the spread of pests and diseases, while shrubs and rhododendrons in small color are most likely to get sick in rainy season, resulting in changes and shedding of leaf spots, so we should start spraying drugs regularly before May.
