Rosa glomerata · Rosa glomerata
Grow in fertile, humus-rich, moist but well-drained soil in full sun or partial shade. Ideal grown through a large, established tree. Mulch with well-rotted organic matter in late winter or early spring, and for best flowering apply a general rose or shrub fertiliser in early spring and again in early summer. See rose cultivation
On established plants filling their supports, remove about a third of the oldest stems and shorten sideshoots by about two-thirds; retain and secure replacement shoots. Prune in late summer after the display of flowers and hips.
