Establishment
4-8 weeksNewly planted rose develops root system and begins leaf growth. Growth may appear slow initially as energy focuses on rooting.
Water consistently and deeply. Mulch around base with 2-3 inches of organic material, keeping it away from the cane. Avoid fertilizing for 4-6 weeks after planting to prevent forcing tender new growth.
Vegetative Growth
Spring through early summerRose produces vigorous new canes and dense foliage. Plant develops its characteristic bushy, compact form.
Remove any diseased or crossing canes. Begin light fertilizing once growth is established. Monitor for pests and diseases. Maintain consistent moisture.
First Bloom
6-8 weeksFlower buds form and open into clusters of pure white, semi-double blooms with golden stamens and sweet fragrance.
Deadhead spent flowers to encourage continuous blooming. Apply balanced rose fertilizer every 4-6 weeks. Ensure adequate water during blooming. Watch for aphids on new growth.
Summer Repeat Bloom
June through SeptemberPlant produces subsequent flushes of flowers throughout summer and into fall. Growth may slow in peak heat.
Continue deadheading religiously. Maintain consistent watering, increasing frequency in hot weather. Apply fungicide preventatively in humid climates to prevent rose rosette virus and powdery mildew.
Fall Decline & Dormancy
October through MarchBlooming slows as temperatures cool. Foliage may show fall coloring. Plant prepares for winter rest.
Reduce fertilizer applications in late August. Allow final flowers to set hips for winter interest. In zones 5-6, apply winter protection (mulch mounding to 12 inches). Prune in early spring, not fall.

Harvest Tips
Roses are ornamental cut flowers. Cut stems in early morning when fully hydrated. Use sharp pruners and cut at 45-degree angle above an outward-facing bud eye. For maximum vase life (7-10 days), cut when outer petals are just beginning to open. Remove lower leaves that would sit in water. Change water every 2 days and recut stems.
