Establishment (First year)
12 monthsYoung transplants focus on root development with slow foliar growth. Foliage remains compact and low-growing.
Water regularly to keep soil consistently moist but not saturated. Mulch with 1-2 inches of bark or compost. Protect from harsh winter winds in colder zones. Avoid fertilizing.
Vegetative Growth (Year 2-3)
12-24 monthsPlant fills out with increased branching and denser foliage. Height gradually reaches mature size (12-24 inches depending on variety).
Reduce watering frequency as root system deepens. Deadhead spent flowers to encourage compact growth. Light pruning after frost to remove winter damage. No fertilizer needed.
Pre-flowering (Late spring to early summer)
4-6 weeksFlower buds form at stem tips. Foliage appears robust and healthy with visible terminal buds developing.
Maintain consistent watering without overwatering. Ensure full sun exposure for abundant blooming. Avoid high-nitrogen fertilizers which promote foliage over flowers.
Flowering (Late summer to autumn)
8-12 weeksAbundant small bell-shaped flowers cover the plant in shades of pink, purple, lavender, or white depending on variety. Flowers attract pollinators.
Deadhead spent flowers to maintain appearance and encourage repeat flowering. Water during dry periods. Avoid pruning during flowering to preserve blooms.
Winter Dormancy (Late autumn to early spring)
4-5 monthsFlowering ceases, foliage may take on deeper bronze or reddish tones. Plant enters semi-dormant state with minimal growth.
Reduce watering significantly. Provide winter wind protection in exposed locations. Apply light pruning in early spring before new growth begins. Do not fertilize.
