overwintering pots on Strawberry
Quick answer
If your Strawberry has overwintering pots, the most likely cause is: Strawberry roots in elevated containers lack the thermal mass of the ground. In USDA zones 6 and below, hard freezes can kill the roots if left unprotected on an open balcony.
Start here:
- 1. Move the pots to an unheated but sheltered garage or shed once they go dormant (after the first hard frost).
- 2. If leaving outside, bury the pots in a box filled with dry leaves, straw, or mulch to insulate the roots.
