May to

Habitat of the herb:

Forests, 1500 - 3000 metres in the Himalayas.

Edible parts of Walnut:

Seed - raw or cooked. An edible oil is obtained from the seed, it tends to go rancid quickly.

Other uses of the herb:

The bark and the unripe rind of the fruit are good sources of tannin. 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 also 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.). Wood - hard, strongly grained, polishes well. Used for making furniture, carved work, veneers etc.

Propagation of 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:

Forests, 1500 - 3000 metres in the Himalayas.
