Pruning requirements and precautions for garden plants

1. First-level maintenance

1.1 Lawn Mowing

Considering the seasonal characteristics and the growth and development features of the grass species, the height of the grass should be uniform and the edges neat. The height should be controlled at: 5 cm or less for Taiwan grass, 10 cm or less for large-leaf oil grass, false fruiting grass and step-along grass.

1.2 Pruning of shrubs and flowers

Taking into account the growth and development characteristics of each plant, it is not only aesthetically pleasing in shape but also capable of blooming at the right time, with a variety of colorful flowers. Flowering shrubs and herbaceous flowers should be pruned before flower bud differentiation to avoid cutting off the flower buds. After the flowers wither, the withered flowers and branches should be removed in time. For perennial flowering plants, flower branches should be cultivated purposefully to ensure that there are flowers all year round. The shaping effect of hedges and flower beds should be in harmony with the surrounding environment, enhance the beautification effect of the garden, and be meticulously carved to produce masterpieces.

1.3 Pruning of trees

Considering the growth characteristics of tree species such as the germination period and flowering period, except for palm and other plants, other trees are generally pruned before the differentiation of leaf buds and flower buds to avoid cutting them off, so that flowering trees have abundant flowers and lush leaves. The shaping effect of trees should be in harmony with the surrounding environment to enhance the beautification effect of the garden. When pruning street trees, it is necessary to keep the tree crown intact and beautiful, with the main and side branches evenly distributed and in equal numbers. The inner cavity should not be empty and well-ventilated and well-lit. The height of the lower edge line and the volume of the tree crown should be determined according to different road sections and vehicle conditions. The tree height is generally controlled between 10 and 17 meters. Attention should be paid to not affecting high-voltage lines, street lamps and traffic signs. Trees planted in the affiliated green Spaces of units whose branches and leaves extend into the urban public roads or the property areas of others should be pruned in a timely manner. When pruning, follow the operating procedures, minimize the number of cuts, make the cut flat and no tree nails should be left. Shade branches, drooping branches, suckers below the lower edge and dry branches and leaves should be pruned off in time.

1.4 Pruning of ancient and famous trees

For severely aged ancient trees, the crown part should be heavily pruned, cutting off the aged and withered branches to shorten the nutrient transport line within the tree body, increase the circulation speed of body fluids, and promote the growth of strong branch tips. At the same time, appropriate pruning should be carried out on diseased, rotten, overly aged and pest-infested branches to achieve the purpose of ventilation and light penetration in the tree crown and improve the conditions for growth and development.

2. Secondary management and maintenance

2.1 Lawn Mowing

Taking into account the seasonal characteristics and the growth and development features of the grass species, the height of the grass should be uniform, with neat edges. The height should be controlled as follows: less than 5 cm for Taiwan grass, more than 10 cm for large-leaf oil grass, false fruiting grass and attached grass, and less than 30 cm for 蟛蜞 chrysanthemum.

2.2 Pruning of shrubs and flowers

Taking into account the growth and development characteristics of each plant, it is not only aesthetically pleasing in shape but also capable of blooming at the right time. Flowering shrubs and herbaceous flowers must be pruned before flower bud differentiation to avoid cutting off the flower buds. After the flowers wither, the withered flowers and old branches should be pruned in time. The shaping of hedges and flower beds should meet the requirements of landscaping.

2.3 Pruning of trees

Taking into account the growth characteristics of each tree species, such as leaf buds and bud differentiation periods, determine the pruning time to avoid cutting off flower buds and ensure that flowering trees bloom at the right time. The shaping effect of trees should be as harmonious as possible with the surrounding environment. When pruning street trees, it is necessary to keep the tree crown intact, the density of branches and leaves appropriate, and the inner cavity not empty but well-ventilated and well-lit. The height of the lower edge line and the volume of the tree crown should be determined according to different road sections and vehicle conditions. Generally, the tree height should be controlled between 10 and 17 meters. Attention should be paid to not affecting high-voltage lines, street lamps and traffic signs. Trees planted in the affiliated green Spaces of units whose branches and leaves extend into the urban public roads or the property areas of others should be pruned in a timely manner. When pruning, follow the operating procedures, minimize the number of cuts, make the cut flat and no tree nails should be left. Shade branches, drooping branches, suckers below the lower edge and dry branches and leaves should be pruned off in time.

2.4 Vertical Greening Pruning

Pruning should take into account the growth and development characteristics of the species, determine the pruning time and extent, avoid cutting off useful leaf buds, flower buds and main vines, reasonably prune overly dense side vines, control main vines, make the coverage uniform, and enhance the effect of garden greening and beautification. The hanging vines on the overpass should be pruned in time to avoid hindering traffic.

3. Three-level management and maintenance

3.1 Lawn Mowing

Considering the seasonal characteristics and the growth and development features of the grass species, the edges of the green space should be kept neat. The height of the 蟛蜞 chrysanthemum should be controlled under 30 centimeters, and the height of the other grass species should be adjusted according to the situation to create a natural landscape effect in the green space.

3.2 Pruning of shrubs and flowers

The design should be aesthetically pleasing and in harmony with the environment. Flowers should bloom at the right time, and withered flowers and fallen leaves should be pruned promptly.

3.3 Pruning of trees

Timely prune off dry and diseased branches and leaves.
