Establishment
4-6 weeksNewly planted rose with fresh growth emerging from canes; initial root system developing

Vegetative Growth
6-8 weeksPlant develops full canopy of glossy green foliage with vigorous new shoots branching throughout the shrub
Continue regular watering and mulching. Begin light feeding with balanced rose fertilizer. Pinch branch tips to encourage bushiness. Monitor for pests and disease.
Budding & First Bloom
4-6 weeksNumerous flower buds form at branch tips and along canes; first semi-double flowers emerge showing orange-red and golden-yellow coloring

Continuous Flowering

Deadhead spent flowers regularly. Fertilize every 2-3 weeks through mid-summer. Maintain consistent watering. Reduce feeding in late summer to harden plant for winter.
Dormancy Preparation & Winter
