Establishment
3-6 months after plantingYoung shrub developing root system and branching structure, sparse foliage and few or no flowers
Water regularly during first growing season. Mulch lightly. Avoid heavy pruning. Provide structural support if needed in windy locations.
Vegetative Growth
Late spring through mid-summerShrub produces new shoots and gray-green aromatic leaves; compact, bushy form develops
Water when soil is dry. Prune in early spring to shape and encourage branching. Remove dead wood. Fertilize lightly in spring if needed.
Pre-flowering
Mid to late summerFlower buds begin to form at branch tips; shoots continue elongating
Maintain moderate watering schedule. Reduce nitrogen fertilizer to promote flowering over foliage. Full sun exposure critical at this stage.
Flowering
Late August to first frost (8-12 weeks)Dense panicles of bright blue flowers appear on branch tips; peak bloom occurs mid-late summer through first frost
Deadhead spent flowers to encourage continued blooming. Maintain consistent but not wet soil. Full sun maximizes flower production and color intensity.
Dormancy
November to MarchFoliage declines and dies back after hard frost; shrub enters winter rest period
In cold zones (5-6), prune back to 12 inches above ground in early spring after last frost risk. In warmer zones, light pruning suffices. No water needed during dormancy.
