WHEN TO SET OUTSIDE
A late spring to early summer bloomer, this plant can be set in the ground in spring when there is still the possibility for a light frost, up until early summer. It can also be planted in early autumn.
PLACEMENT & CULTIVATION
Pink 'Bats Double Red' is best crowding border edges and well-drained rock gardens, where it attracts butterflies and bees. If mulching to suppress weeds, use a layer of fine gravel. Shear after bloom in summer. Winter killed stems can be pruned away in springtime. Divide every two-three years to renew vigor—in early spring for zones 3-6 or fall in zones 7-9.
Water regularly during first growing season, about 1" per week, watering mornings only. Once established water during especially prolonged dry periods. Avoid overwatering and saturated soils.
Tolerates most soil pH levels, but neutral to alkaline is preferred. If soil is acidic, apply a handful of lime when planting.
Apply a low-nitrogen granular, organic fertilizer or 2" of compost in springtime.
