What planters can stay outside in winter?
Fiberglass, lead, iron, heavy plastic, and stone are the best weather-resistant containers to use; terra-cotta will eventually expand and crack with repeated freezing and thawing. Assemble your designs early enough that the plants have time to acclimate to their new pots before the hard freeze. In this case, a frostproof pot with a drainage hole is important. Fiberglass, lead, iron, heavy plastic, and stone are the best weather-resistant containers to use; terra-cotta will eventually expand and crack with repeated freezing and thawing.Avoid terra-cotta pots for moisture-loving plants like ferns, Venus flytraps, and peace lilies since the porous clay dries out the soil quickly. Outdoor evergreens need frost-resistant pots—standard terra-cotta may crack in winter unless it’s a high-quality variety like Italian Impruneta.Choose The Right Containers Terra-cotta and ceramic pots absorb moisture, which expands as it freezes and cracks the container. Metal, concrete and wood containers typically handle freezes well, as do fiberglass and resin pots. Some plastic pots also survive winter fine, but may become brittle over time.
