PLACEMENT & CULTIVATION
Carthusian pink is a graceful, airy plant that seduces gardeners with its vivid sparks of fuchsia pink flowers perched atop thin agile stems. It attracts butterflies and bees and fends off deer predation. Deadheading will promote additional flowering during summer. To increase your patch of this pink, resow from seeds or divide every 2-3 years. For zones 3-6, early spring is the time for this, while in zones 7-9, divide in the fall.
Water regularly during first growing season, about 1" per week. Once established, only water during especially prolonged dry periods.
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.
