Rubus coreanus (common name: korean bramble)
Propagation: Seed - requires stratification and is best sown in early autumn in a cold frame. Stored seed requires one month stratification at about 3°c and is best sown as early as possible in the year. Prick out the seedlings when they are large enough to handle and grow on in a cold frame. Plant them out into their permanent positions in late spring of the following year.
Division of the suckers in early spring or just before leaf-fall in the autumn[1].
Cultivation: Easily grown in a good well-drained loamy soil in sun or semi-shade[2][3][1].
Plants are rarely cultivated for their edible fruit in Japan[4].
This species is a raspberry with biennial stems, it produces a number of new stems each year from the perennial rootstock, these stems fruit in their second year and then die[1].
