Matters needing attention in Buckeye Culture

Diseases and insect pests

During the breeding period, we must pay attention to the diseases and insect pests of the seven-leaf tree, the common pests are: green moth, copper green beetle, golden caterpillar, mulberry longicorn beetle, etc., pay attention to prevention and control.

Pruning

Pay attention to pruning the seven-leaf tree, either in winter or before sprouting in spring, pruning long branches and trimming into a natural round head.

Change the basin

Because the seven-leaf tree grows fast and consumes a lot of nutrients, it is necessary to change the basin once a year to ensure adequate nutrition.

1. Distribution of origin

Native to the Balkans of Europe, it has been successfully introduced in North China.

2. Morphological characteristics.

The crown is round, the branches are luxuriant, the flowers bloom at the end of March, the panicles are large and pink, and the leaves turn yellow in autumn. Bark grayish brown, flaky. Branchlets stout, chestnut brown, smooth glabrous. Leaflets usually 7, Obovate-long elliptic. The florescence is in May. The flowers are small and red. Fruit globose or Obovate, reddish brown, mature from September to October. Is a very ideal street trees, landscaped trees. At the beginning of the new leaves in spring, the leaves are as red as blood, very gorgeous. In summer, it will also show multi-color because of the different growth of leaves, with reddish upper part, bright green in the middle and dark green in the lower part. In autumn, the leaf color is as yellow as gold, so it is also known as discolored wood. The tree is straight and majestic. When blooming, the red panicle is covered with crowns, green trees and red makeup, very beautiful.

The characteristics of the capsule are unknown. Flowering in May.

2. Distribution range

Produced in southwestern Yunnan. Born in the jungle 1500 meters above sea level. The type specimens were collected from Lancang.

3. Species differences

This species is closely related to the Yunnan seven-leaf tree (A. wangii Hu). The difference is that the leaflets of this species are glabrous and the apex is acute. The middle leaflet is often larger than the bilateral leaflet; the thyrse is narrower and the base is only 5 cm in diameter. Compared with A. assamica Griff., the petiole of this species is shorter, the leaflets are papery, smaller, the middle leaflet is slightly larger than the leaflets on both sides, the thyrse is narrower, the diameter of the base is only 5 cm, the floret is short and sparse, and the length is only 2-2.5cm, and the distance between the two inflorescences is about 2 cm.
