Overwintering Potted Arborvitae in Wisconsin

Wisconsin gardener bought 12 American arborvitae in 1-gal pots. Asked how to keep them until spring planting—indoors by window? Worried roots would freeze in pots.

The expert said: keep cool but not freezing (32°F+). Unheated garage with window or enclosed porch ideal. Not in heated house. Water weekly—roots still grow. Keep soil damp, not wet. Spring: plant in 2× root ball holes, good soil, mulch 3 in., water.

Winter Storage

• Temp: 32–45°F (garage/porch).
• Light: some natural light.
• Water: weekly, damp not soggy.
• Plant spring: wide hole, mulch, water.
