How do horse chestnut trees grow?

1. planting pit

Buckeye taproots are deep and lateral roots are few, belonging to tree species that are not resistant to transplantation, so they must be transplanted with soil balls, the diameter of which is 6 to 8 times that of tree DBH. Buckeye planting should be carried out before germination in early spring or after all leaves have fallen off in late autumn. In order to improve the survival rate of planting, the planting pit should be dug as much as possible before planting, which is conducive to the growth of plants. When planting, attention should be paid not to too deep, too deep easy to lead to plant bud, generally speaking, planting depth can be slightly higher than the soil ball epidermis 3 cm to 5 cm. Backfill should be layered and firm when planting.

2. watering

After planting, water should be poured immediately, two times after a week, and three times after 10 days. After three waters, water can be watered according to soil moisture content. Generally, water can be poured once a month. July and August are periods of abundant precipitation. Water can be less or not watered. Water can be poured once in September and October respectively. At the end of November or early December, water can be poured thoroughly. In early March of the next spring, it should be watered enough to thaw water. April and May are spring drought periods. Spring monsoon lasts for a long time, and the wind is strong. The transpiration of plants is relatively large. Therefore, the watering frequency can be increased. It can be watered once every 15 days. Thereafter, it should be watered once a month. Cold water is poured at the end of autumn. The third year is watered according to the method of the second year. From the fourth year onwards, water must be poured five times a year, thawing water in early spring, water before flowering, water after flowering, fruit expansion water and frozen water at the end of autumn. Every watering is very important, and it is necessary to irrigate enough water. In addition, the dry season should also be supplemented in time for water, which is conducive to the growth of plants, can make the crown plump, strong branches.

3. fertilization

Buckeye like fertilizer, so before planting should apply sufficient base fertilizer, base fertilizer to cattle and horse manure, rotten leaf fertilizer and other farm manure is appropriate, although these fertilizers fertility is small, but soft, to improve the porosity of the soil is also good. Base fertilizer should be mixed well with planting soil. Adequate fertilizer can accelerate its growth rate and improve the plant's resistance to pests. In addition to applying base fertilizer at planting time, fertilizer should also be applied throughout the growing season, including some large-sized street trees. Urea can be applied once in the middle of June of the first year of planting. This fertilizer can promote the growth of branches and leaves and increase the nutrient area. In late August, phosphorus and potassium fertilizer can be applied once. This fertilizer can improve the lignification degree of new branches of plants, improve the ability of resistance to freezing injury, and help plants survive safely. In late autumn, combined with pouring frozen water, some semi-decomposed fermented rotten leaf fertilizer can be applied. The fertilizer amount can be large and should be applied shallowly. Urea can be applied once at the beginning of April in the following spring, phosphorus and potassium fertilizer can be applied once in the middle of August, and farm manure can be applied once at the end of autumn according to the method of the previous year. The third year can be fertilized according to the second year method. From the fourth year onwards, the three-element compound fertilizer can be applied once a year in spring, and the farm manure can be applied once in late autumn. This is conducive to accelerating plant growth and safe winter of plants.

4. pruning

The shaping and pruning of horse chestnut should be carried out in winter after annual defoliation or before germination in the following spring. Because the crown of horse chestnut is naturally round head shape, it is better to keep the original crown shape. Plastic pruning is mainly to keep the crown beautiful, ventilation and light transmission as the principle, too dense branches are thinned, too long branches are truncated, so that branches are evenly distributed and grow healthily. Also dry branches, pest branches, bore branches, slender branches and poor growth branches will be cut off, conducive to concentrated supply of nutrients, forming a good crown.
