Overwintering Potted Bleeding Hearts and Tree Roses in Zone 5/6

Bleeding hearts (Dicentra) in large pots can stay outdoors in Connecticut (zone 5/6) if protected from north winds. They require a cold dormancy period, so don't bring them indoors. Mulch the pots with straw, leaves, or cypress chips for root insulation.

Tree Roses in Containers

Tree roses (standards) can grow in large pots, but winter survival is trickier. Choose cultivars rated for your zone. In zone 5/6, pots need serious protection: move to an unheated garage, wrap with burlap, or heap mulch around the container. Consult your local Master Gardener or County Extension (Hartford County: UConn Extension) for variety recommendations.

Key point: both plants need cold dormancy; never keep them in a heated space over winter.
