When to Buy & Plant Double Knock Out Rose
Price Seasonality
Bare-root roses (January-March) are cheapest but limited selection. Potted roses peak in spring. End-of-season clearance offers 20-40% off.
Pro tip: For Knock Out roses, fall planting works well in zones 6-9. Bare-root in late winter is cheapest.
