Care Notes

Plant in well-drained to moist, amended soil. Water well after planting; maintain 1” of water once a week the first year. Cut back the entire shrub down to 6-18” in late winter or early spring. No staking is required if planted close together (3’ apart) to support each other. Deadhead flowers anytime for repeat blooming. Feed early spring and mid-summer with a slow release fertilizer. Follow label instructions. Mulch 2″ to suppress weeds, retain moisture and protect against extremes of soil temperature.
