Knock Out Rose

Rosa 'Knock Out'

Care guide

Pruning & Shaping

Prune early-to-mid March. Reduce by one-third to one-half. If the plant is oversized or leggy, it can be cut back harder to 12-18 inches without harm.

Draper timing note: Wait until the soil is workable AND the 10-day forecast shows no hard freeze below 20 °F before pruning.

Transplanting & Establishment

Early-to-mid March. Lightly prune before moving. Preserve a wide root ball. Monitor moisture carefully after replanting — Knock Outs are tough once established but need consistent water while re-rooting.

Seasonal Care

Early-mid March: Prune (1/3 to 1/2). Transplant if needed. Watch moisture closely through spring establishment.
