Growing 'Blue Moon' Roses in Wisconsin: Winter Protection Strategies

'Blue Moon' Hardiness Limits

'Blue Moon' is a fragrant hybrid tea but only hardy to about Zone 6. In southwestern Wisconsin (Zone 4/5), it will not survive winter unprotected.

Options for Cold Climates

• Heavy mulch cage: Cut back to 12 inches in late fall, surround with chicken wire, fill with straw or leaves.
• Container growing: Plant in a large pot, sink in ground for summer, move to unheated garage (30–40°F) for winter. Water sparingly.
• Treat as annual: Enjoy for one season, replace yearly.

Key Tip

Do not fertilize after mid-summer. Let canes harden. The fragrance is exceptional—worth the extra effort if you have space for a pot or cage.
