How can landscaping be maintained to achieve coordinated and healthy growth?

【1】 Maintenance and management of grassland.

1. Recovery and full growth stage: Prevent water stains in spring, protect from direct sunlight in summer, and keep from wind and moisture in autumn and winter.

2. Vigorous growth stage (2-5 years) : The focus is on maintaining greenery and avoiding yellowing.

3. Slow growth stage (6-8 years) : Pay attention to the prevention and control of diseases and pests.

4. Grassland degradation stage (after 10 years) : Effectively delay grassland degradation and rejuvenate the lawn.

5. Moisture Management:

When the grass stems are turned over, the soil is dry but not white, and moist but not soaked. The principle is that it is dry in spring and summer and wet in autumn and winter throughout the year.

6. Fertilization:

Apply it gently and thinly. Use less urea from April to September and more at both ends. After each mowing, apply 2 to 4 jin of urea per mu.

7. Vigorous growth season:

Control fertilizer and water supply to control the growth rate.

8. Pruning

It is advisable to mow the grass 8 to 10 times a year. On average, mow once a month from February to September, and every two months from October to January of the following year.

【2】 Maintenance and management of hedges.

1. Fertilizer and water management for hedges:

Fertilization principles: Sufficient base fertilizer and rapid top dressing. It is mainly composed of nitrogen, with phosphorus and potassium combined. Apply thin fertilizer frequently. It must be applied after pruning. If necessary, apply foliar fertilizer.

2. Moisture Management:

The main focus is on moisture retention. The topsoil should be dry but not white. After rain, drain the water to prevent waterlogging, which may cause root rot and affect growth.

3. Trimming of hedges:

Transplant the apical growth advantages of plants, accelerate the shaping process, and meet the design appreciation effect.

The principle of pruning:

It has been trimmed many times from small to large, with smooth lines and formed as needed

The technical requirements for initial pruning: Pruning should start when the hedge grows to a height of 30 centimeters.

The time for repeated pruning: Prune when the new branches and leaves grow to 4 to 6 centimeters. Pruning is not advisable at noon, on rainy days, in strong winds or foggy days.

Pruning operation:

The blade is sharp and closely adheres to the hedge surface, with few or heavy cuts that are not exposed. Cut more of the protruding parts that grow vigorously and less of the sunken parts that grow weakly. Straight and flat sections can be trimmed by drawing lines. The green shape should be pruned according to the shape, with more pruning at the top and less around the edges.

Pest and disease control of hedges:

Hedges are mainly infested with powdery mildew, leaf miners, psyllids, scale insects and aphids. The main diseases are leaf spot disease, brown spot disease, leaf drop disease, etc.
