2-4 yearsProgressive expansion of stems and foliage; dense branching develops
Reduce watering frequency as roots deepen. Minimal pruning needed; remove dead or crossing branches only. No fertilizer required—thrives in poor soils.
Maturation
Ongoing after 5-10 yearsShrub reaches full size and form with thick, woody stems and dense canopy
Established plants need no supplemental water in native range. Light pruning to maintain shape acceptable. Monitor for pests but generally very healthy.
