Growth—

Rubus argutus grows best in a warm temperate climate with mild winters and no distinct dry season. It is tolerant of continental climates with hot summers and cold winters and also of more tropical climates, so long as there is rainfall all year round[1]. It can tolerate moderate frosts, with some provenances of the plant perhaps surviving occasional falls to as low as -25°c for short periods[1]. Easily grown in a good well-drained loamy soil in sun or semi-shade[2, 3, 4]. The plant is adapted to a broad range of soil textures. It grows best in full or partial sun but under drier conditions can become desiccated. Habitats ranging from wet to mesic are suitable), including boggy sites. Its drought tolerance is only moderate and it does not tolerate salinity[1]. Plants in this genus are notably susceptible to honey fungus[4]. This species is occasionally cultivated for its edible fruit in N. America, and is a parent of many cultivated forms[[5, 6, 1]. Rubus louisianus (generally considered to be a synonym of this species) is probably the wild form of the cultivar 'Crystal White blackberry' which in the USA is locally (e.g. Illinois) grown for its fruits[7].

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. Cuttings of half-ripe wood, mid summer in a frame[4]. Tip layering in July. Plant out in autumn. Division in early spring or just before leaf-fall in the autumn[4].
