Overwintering Peonies and Daylilies in an Unheated Garage

To save prized peonies and daylilies during construction:

1. Dig up the most valuable plants, dividing if needed. Get a good root section.
2. Pot in containers with good soil (lots of compost), no fertilizer.
3. Place in the back of an unheated garage or barn.
4. Cover with old blankets/quilts for darkness and insulation.
5. Check monthly; give 2–3 oz water to prevent desiccation.

The expert successfully overwintered 'Lady Alexandra Duff' peony this way in Zone 5a. Both structures work; darkness maintains dormancy. Replant in spring after ground thaws.
