Horse chestnut origin

The horse chestnut (Aesculus hippocastanum) is a deciduous tree and belongs to the soapberry family. It originally comes from southeastern Europe and Asia Minor and is now cultivated in many parts of the world as an ornamental plant and for its medicinal properties. It can usually reach a height of 15 to 25 m.

The horse chestnut has a grey-brown bark that becomes scaly and cracks with age. Its leaves are palmately compound and consist of five to seven leaflets, which together can grow up to 30 cm long. 
In May and June, horse chestnuts bear large, striking white or pink flowers. They appear in dense, upright panicles and give off a sweet scent.
In autumn, the trees bear brown, round capsule fruits that contain the so-called horse chestnuts.

The fruits are inedible and slightly poisonous for humans, but are eaten by wild animals such as deer or wild boars. 
The fruits of horse chestnuts contain a substance called aescin, which has antimicrobial properties and can therefore be used as a natural detergent.

Many parts of the horse chestnut are used in medicine, as well as in cosmetics and the paint industry. It is a popular tree in towns, parks and gardens and its seeds are very popular with children for crafts in the autumn.

Horse chestnut care and location

Horse chestnuts prefer a sunny to partially shaded location with deep, fresh to moist, and nutrient-rich soil that is well-drained. They are adaptable and can also grow in dry soils, but should be watered regularly during dry periods and on sunny days to prevent the soil from drying out completely.

Pruning horse chestnut

Horse chestnuts do not have to from geschnitten They will grow long, but can be pruned back for shaping or rejuvenation. The best time for pruning is late summer, as wounds heal better then. To keep the tree healthy, old and diseased branches should be removed.

Fertilizing horse chestnut

Horse chestnuts have a high nitrogen, phosphorus and potassium requirement, so regular fertilization It is recommended that in spring a 1–2 cm thick layer of mature garden compost be applied to the base of the tree. A layer of mulch around the horse chestnut is beneficial to keep the soil moist and suppress weeds. The mulch should not be applied too thickly, as this could damage the bark of the horse chestnut.

Watering horse chestnut

Due to climate change, it is getting hotter in our regions, resulting in longer dry periods. This has an impact on the environment and especially on trees. Depending on the location and the climatic situation, it may be more frequent watering than necessary in previous years. Adequate watering of young and newly planted horse chestnut trees is especially important, as their root systems are not yet fully developed and they are therefore more susceptible to drought stress. The substrate around the tree should never dry out completely. This weakens the trees and carries the risk of the fine roots dying.

The water requirements of a horse chestnut tree depend on several factors, such as the length of the dry period, the condition of the tree, and the soil. Generally, 75 to 100 liters per watering can be estimated for young trees and 200 liters for older trees. To ensure consistent moisture, tree bath watering bags are recommended. With conventional watering, only a fraction of the water poured is directly absorbed by the tree. Large amounts of water only penetrate the soil surface and evaporate.
With tree bath watering bags Over a period of several hours, water is released drop by drop through two small holes onto the horse chestnut tree. This ensures consistent moisture levels, allowing even the roots near the surface to absorb the water effectively. Filling one watering bag provides young trees with sufficient water.
For existing trees with a larger trunk diameter, two to three irrigation bags can be zipped together to water them.
