What is the best material for an outdoor planter?
Fiberglass, metal, glass fiber reinforced concrete, and uv-resistant plastic outdoor planters are all common selections based on their weather-resistant properties and overall durability. Fiberglass planters fiberglass is the go-to choice for urban gardeners who value both strength and portability. It’s lightweight yet durable, and can mimic high-end finishes like ceramic, stone, or even metal.
What planters can stay outside in winter?
Choose The Right Containers 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. Winter sunlight can fade fiberglass and resin pots. 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.
