Establishment
3-6 monthsYoung plant with developing root system and compact branching structure. Foliage is gray-green and relatively sparse.
Water consistently during first season to establish roots. Protect from harsh winds and extreme cold. Avoid fertilizing heavily.
Vegetative Growth
6-12 monthsShrub develops dense branching and fuller foliage. No flowers yet or minimal flowering as plant matures.
Light pruning to shape and encourage branching. Continue moderate watering. Mulch around base to retain moisture and regulate soil temperature.
Flowering
8-12 weeks during winter-springAbundant small, tubular white flowers appear along stems, typically in winter and spring (December-May in Northern Hemisphere).
Do not over-fertilize, which reduces flowering. Deadhead spent flowers to encourage continued blooming. Provide protection in areas with frost.
Post-Flowering
3-4 monthsFlowers fade and plant enters summer dormancy with reduced growth. Foliage remains healthy and gray-green.
Reduce watering in summer months. Light pruning after flowering to maintain shape. Watch for pests during warmer months.
Dormancy/Maintenance
2-3 monthsPlant slows growth in late summer and fall, preparing for next winter's flowering cycle.
Minimal watering. Hold off fertilizing. Inspect for spider mites and scale insects. Clean up any fallen debris.
