Juglans mandshurica seed

LATIN NAME: JUGLANS MANDSHURICA

COMMON NAME: Manchurian Walnut

The Manchurian walnut unfurls the huge, pinnate leaves with the many pairs of the pointed leaflets, the long, drooping catkins of the male flowers, and the thick-shelled, ridged nuts that follow through the autumn. The tree grows into the tall, broad-crowned giant of the river valleys, the bark stays dark and furrowed, and the whole plant carries the bold, woodland look of the true walnuts. The nuts ripen inside the green, fleshy husks, rich and oily, and the timber ranks among the finest of the hardwoods. It likes the sun, the deep, rich, moist soil, and the sheltered position.

Scientific Research & Plant Biotechnology

For the breeders of the hardy nuts, the Manchurian walnut is the cold-country parent they keep coming back to. The species appears in the crosses that push the walnut cultivation into the harsher regions, and the researchers study the nut quality, the seed dormancy and the growth on the cold sites. The foresters value the straight, handsome timber, and the juglone chemistry of the husks and the leaves, which shapes the ground around the tree, keeps the laboratories interested.

Ecological & Economic Value & Wide Applications

The Manchurian walnut anchors the cold-region landscape with the bold, architectural crown, and it pays its way twice over. The beautiful, figured wood serves the fine furniture, the veneers and the gun stocks, and the rich, oily nuts are edible and prized. The fallen nuts feed the squirrels and the birds, the dense crown shelters the woodland, and the tree stands for the generations. A tree of value and character in one.

The Manchurian walnut seeds grow well in a deep, rich, gritty soil kept moist and cool. The big, vigorous seedlings rise on the strong stems, and they grow on fast through the first summer. Plant them out early into their permanent place, because the walnuts hate the moved roots, and give them the deep, rich, moist ground and the full sun. Stake them while the young stems settle, and the huge pinnate leaves will unfurl with the first season. The first nuts come within the few years.

To grow the Manchurian walnut from seed, sow the large, hard seeds singly into the deep flat of rich, gritty soil, then cover them well, keep the flat in the bright, cool spot and water gently. The seedlings thread up within a few weeks, and they grow on steadily. Stand the young trees in the deep, rich, moist ground, and the bold crown will unfurl through the years.
