Yes, moving your urban planter boxes indoors during a frost warning is one of the most effective ways to protect sensitive plants. A hard frost can damage or kill non-hardy plants in containers much faster than those in the ground, as the soil in planters loses heat more rapidly. For a successful move, act before the frost arrives. Lightweight boxes can be carried inside to a garage, sunroom, or even a bright hallway. For heavier containers, consider using a plant caddy with wheels. This strategy is ideal for tender perennials, herbs like basil, and tropical plants. However, avoid bringing in plants with pests or diseases. If moving them is impossible, alternative outdoor protections like frost cloths, mulch, or grouping pots together against a wall can also provide critical shelter from the cold.
