Establishment
4-8 weeksYoung transplant with minimal branching; root system developing below soil surface
Water regularly (every 2-3 days in hot weather) to establish deep roots. Avoid fertilizing first month. Mulch lightly around base, keeping away from stem.
Vegetative Growth
3-6 monthsPlant develops multiple stems and spreads outward; fine, needle-like foliage becomes denser
Reduce watering frequency as roots establish. Light pruning to encourage bushiness. No fertilizer needed; prefers lean soil.
Flowering
Spring through early summer (3-4 months); may bloom sporadically year-round in warm climatesAbundant small white flowers appear along stems, creating an airy, cloud-like appearance
Maintain consistent but infrequent watering during bloom. Do not over-fertilize, which reduces flowers. Remove spent flowers to encourage continuous bloom.
Maturity & Maintenance
Ongoing (1+ year)Plant reaches full spread; flowering continues; can become woody if neglected
Prune annually after flowering to maintain shape and density. Water only during extended drought. Remove dead wood. No routine fertilizing required.
