Spring Uncovering and Fertilizing Schedule for Roses in Cold Climates

Spring Uncovering and Fertilizing Schedule for Roses in Cold Climates

In northwestern Ontario, uncover after hard frost danger passes. Remove straw first, then soil a week later. Roses tolerate light frosts but not repeated ones.

Fertilizing

• Apply fertilizer any time after uncovering, but it works best above 70°F.
• Any rose fertilizer is fine; organic gardeners prefer fish fertilizer (monthly drench or foliar spray).

Winter Prep

Stop fertilizing and deadheading after August to encourage dormancy and cane hardening for winter survival.
