The walnut is a green flowering plant. It produces small green flowers. The male catkins hang down, about 5-10 cm long, rarely reaching 15 cm. The bracts, bracteoles and tepals of the male flowers are all covered with glandular hairs. There are 6-30 stamens, and the anthers are yellow and hairless. The female spike usually bears 1-3 (or more) female flowers. The involucre of the female flower is covered with very short glandular hairs, and the stigma is light green.

When do walnut trees bloom?

In the south, the blooming period of walnut trees is generally from March to April, while in the north it is a bit later, around May. Traditional walnut trees take 12-15 years from germination to bearing fruit. In recent years, through scientific research, breeding and crossbreeding, the shortest time from walnut germination, grafting to fruiting is now only 4-5 years, and from 8-10 years they begin to enter full fruiting earlier. If the walnut tree is grafted, it can bear fruit in 3-5 years.

Growth Habits

The walnut prefers light, is cold-resistant, and has strong drought and disease resistance. It adapts to growth in various soils and prefers fertile, moist sandy loam. It likes water, fertilizer and sunlight, yet is not strict about water and fertilizer requirements. After leaf drop and before germination, pruning is not advisable, as it easily causes bleeding. It is suitable for growing in most soils. It prefers calcareous soil and is commonly found in areas with deep soil layers along both sides of mountain valleys.
