2-6 monthsLeaf development and branch expansion; plant fills out with green foliage
Reduce watering frequency as roots establish; avoid fertilizing; prune lightly to encourage bushiness if needed
Pre-flowering
1-3 monthsPlant maturing with fuller canopy; flower buds beginning to form at branch tips
Maintain dry conditions; cease fertilizing; ensure excellent drainage; light pruning acceptable
Flowering
4-8 weeks, peak bloom varies by speciesDense clusters of tubular or rounded flowers appear; spectacular color display, often fragrant
Minimize disturbance; maintain consistent watering schedule; avoid overhead watering to prevent flower damage; deadhead spent blooms to encourage reflowering in some species
