Cultivation Details
Juglans mandschurica is is a very cold-hardy plant, able to tolerate temperatures down to around -25°c when fully dormant. It prefers a continental climate with its hot summers, cold winters and usually a clear movement from one season to another. It is easily excited into growth as the season warms up and, in areas where periods of mild weather can be interspersed with a return to cold conditions, this new growth is very susceptible to damage by temperatures near to or below freezing
Requires a deep well-drained loam and a sunny position sheltered from strong winds[
