Dormancy/Planting
2-4 weeksBare-root or container rose is planted with canes cut back to 12-18 inches; new growth begins to emerge from buds
Plant in early spring or fall. Remove any broken canes. Mound soil 8-10 inches around base in cold climates. Water thoroughly after planting.
Vegetative Growth
4-8 weeksNew shoots and leaves rapidly emerge and expand; plant establishes root system and builds cane structure
Remove any dead wood. Apply balanced fertilizer every 2-3 weeks. Mulch around base with 2-3 inches of organic material. Monitor for pests.
Budbreak & Flowering
Continuous spring through fall (8+ weeks per flush)Rose produces flower buds on cane tips and lateral shoots; buds develop into characteristic red-and-white splashed blooms
Deadhead spent blooms above first 5-leaflet leaf to encourage more flowers. Feed with rose fertilizer or bloom-boosting formula. Ensure consistent watering.
Mid-Summer Stress
4-8 weeks (varies by region)Growth may slow during extreme heat; flowering can diminish; plant may appear less vigorous
Increase watering frequency. Apply 3-4 inches of mulch to cool soil. Avoid fertilizing during peak heat. Provide afternoon shade in zones 8-9.
Fall & Hardening Off
6-10 weeks until frostGrowth resumes as temperatures cool; final flush of blooms appears; plant prepares for dormancy with thickened canes
Reduce nitrogen fertilizer; apply potassium-rich fertilizer to harden canes. Stop deadheading 4-6 weeks before first frost. Reduce watering gradually.
