Establishment
4-6 weeksNewly planted seedlings or transplants develop a shallow root system and begin producing needle-like foliage
Water regularly during first 4-6 weeks to establish roots. Avoid overwatering. Mulch lightly with coarse sand if needed. Protect from extreme wet conditions.
Vegetative Growth
Late fall through early springPlant develops dense mats of thin, linear evergreen foliage in shades of green. Spreads horizontally across soil surface.
Reduce watering once established. Allow soil to dry between waterings. No fertilizer needed on poor soils; rich soil may reduce flowering. Avoid nitrogen-heavy fertilizers.
Pre-flowering
2-3 weeks before bloomBuds form at stem tips as day length increases. Foliage may take on reddish or purplish tints in winter.
Continue minimal watering. Do not fertilize. Ensure excellent drainage to prevent winter rot. Light frost enhances color.
Flowering
3-5 weeks (spring, typically April-May in northern zones)Plant produces profuse five-petaled flowers in pink, purple, red, lavender, or white, covering the foliage almost completely
Enjoy blooms without deadheading for continuous color. Water only if extremely dry. No fertilizing needed. Flowers last 3-4 weeks.
Post-flowering & Dormancy
June through early springFlowers fade and foliage remains evergreen through summer and into winter, ready for next spring's bloom cycle
Trim lightly after flowering if desired to encourage denser growth. Reduce summer watering. No supplemental feeding needed. Plants are fully winter hardy.
