Habitat of the herb:

Mixed woods in rich soils, also by mountain streams. Mixed forests on mountain slopes or in valleys at elevations of 500 - 2800 metres.

Edible parts of Manchurian Walnut:

Seed - raw or roasted. The kernels are well filled but difficult to extract because the shell is thick. An edible oil is obtained from the seed, it tends to go rancid quickly.

Other uses of the herb:

The seed contains up to 52% oil and, as well as being edible, it has industrial uses. A rope is made from the bark of young trees. Plants produce chemicals which can inhibit the growth of other plants. These chemicals are dissolved out of the leaves when it rains and are washed down to the ground below, reducing the growth of plants under the tree. The roots of many members of this genus produce substances that are toxic to many plant species, especially apples (Malus species), members of the Ericaceae, Potentilla spp and the white pines (certain Pinus spp.). The inner bark is used to make heel pieces for straw shoes. Sometimes used as a rootstock to confer greater cold resistance. Wood - hard, durable. Used for veneer, furniture etc.

Propagation of Manchurian Walnut:

The seed is best sown as soon as it is ripe in individual deep pots in a cold frame. You need to protect it from mice, birds, squirrels etc. The seed usually germinates in late winter or the spring. Plant out the seedlings into their permanent positions in early summer and give some protection from the cold for their first winter or two. The seed can also be stored in cool moist conditions (such s the salad compartment of a fridge) over the winter and sown in early spring but it may then require a period of cold stratification before it will germinate.

Cultivation of the herb:

Mixed woods in rich soils, also by mountain streams. Mixed forests on mountain slopes or in valleys at elevations of 500 - 2800 metres.
