Planting Knock Out Roses in Pots for Senior Gardeners in Nashville

Knock Out roses thrive in containers if the pot is large enough (18+ inches deep) to prevent root crowding and overheating. Plastic pots are best—ceramic/terra cotta overheat in sun.

Container Recipe

Use bagged potting mix (not garden soil) for drainage.
Add slow-release fertilizer (Osmocote 14-14-14) at planting.
Mulch 3 inches deep to retain moisture and cool roots.
Water when top inch is dry—daily in summer heat.

Plant before November frost; they'll establish roots over winter.
