Overwintering Gift Miniature Rose in Erie County, NY: Garage Dormancy Best

An Erie County, NY (zone 5b) gardener received potted miniature rose for Thanksgiving. Ground frozen, asked about indoor window care vs. outdoor planting.

Best Plan: Unheated Garage Dormancy

Roses NEED cold dormancy to set buds properly. No cold = poor flowering next year.

1. Unheated garage/sunporch (30-45°F ideal)
2. Gradual transition from house to garage over 1 week
3. Water sparingly—just prevent desiccation
4. No fertilizer
5. Plant outside April after frost danger

Plan B: House Window (Less Ideal)

• Cool room (60-65°F), south window
• Mist daily for humidity
• Watch for spider mites
• Expect weaker spring performance

Mini Rose Types Matter

European/Florist (Poulsen): 75% of gift minis. Long shelf life, short-day blooming, tolerate dry air. Tough but not garden-hardy.
American/Garden Center: Hardy, need full dormancy.

Your gift is likely Poulsen. Garage dormancy gives best results for either type!
