Growth Stages

Establishment

4-6 weeks

Newly planted rose developing root system; minimal above-ground growth; may appear dormant for 2-4 weeks

Water gently but consistently; avoid fertilizing for first 4-6 weeks; mulch around base; protect from harsh winds

Vegetative Growth

6-8 weeks

Canes elongate with healthy green foliage emerging; plant develops bushy, well-branched structure

Begin light fertilizing; remove any early weak growth; prune to encourage branching; monitor for pests and diseases

Bud Formation & Flowering

Ongoing throughout growing season, 8-12 weeks per flush

Terminal buds develop at cane tips; buds swell and show deep red coloring before opening into full, velvety blooms

Apply balanced rose fertilizer every 4-6 weeks; deadhead spent blooms; maintain consistent moisture; provide afternoon shade in hottest climates

Peak Bloom

2-3 weeks per bloom flush

Large, deep crimson-red flowers with high-centered form fully open; strong fragrance evident; excellent for cutting

Cut flowers in early morning for longest vase life; continue deadheading to encourage repeat blooming; maintain fertilizing schedule

Dormancy (Winter)

3-4 months (November-March in northern regions)

Plant enters winter rest with minimal growth; foliage may decline; canes become woody and hardened

Reduce watering significantly; apply dormant oil spray; prune in late winter before growth resumes (late February-March); apply winter mulch in zones 5-6

Harvest Tips

Cut flowers in early morning when buds are just opening or in the 'tight mature' stage for longest vase life (10-14 days); cut stems at 45-degree angle; remove lower foliage before arranging; change water every 2-3 days and re-cut stems; deadhead spent blooms on the plant to encourage continuous flowering throughout the season

Fun Facts

🌱 Princess Deep Rose produces blooms with an exceptional fragrance profile that intensifies in warm afternoon sun, releasing more scent than many modern rose varieties—a trait deliberately bred back into the genetics to restore the aromatic quality of heirloom roses.
🌱 The deep crimson-red color of Princess Deep Rose deepens further when temperatures cool in fall, often showing even richer coloration as days shorten and nighttime temperatures drop below 60°F.
🌱 This rose variety has excellent vase life due to its thick, sturdy petals and the way it opens slowly and evenly; a single bloom can remain in an arrangement for 2-3 weeks if properly maintained, far exceeding the typical 5-7 day lifespan of many cut flowers.
