Are plastic pots good for outdoor plants?
Plastic pots are known for their excellent durability, making them an excellent choice among gardeners. Unlike clay or ceramic pots, which can crack or shatter easily under impact or in extreme weather conditions, plastic pots are more resistant to physical damage. With proper care, plastic pots can last for multiple growing seasons without significant wear. They do not degrade as quickly when exposed to sun or moisture, especially if made from UV-stabilised materials.
What planters can stay outside in winter?
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. Glazed terracotta is less porous and more frost-proof. For balcony gardeners, plastic and fiberglass pots are a great shout – they’re lightweight so you can move them around more often and they put up well against water loss and frost.avoid terracotta 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 terracotta may crack in winter unless it’s a high-quality variety like italian impruneta.
Can you leave soil in plastic pots over winter?
If you leave the soil in your containers and moisture gets in the soil, the soil can freeze and expand, damaging your pots. Even resin (plastic) pots can get freeze damage and crack open. Terracotta, plastic, wood, and thin-walled ceramic containers can crack and break when exposed to freeze/thaw cycles. For safety’s sake, bring most glazed ceramics, plastic, composite and terracotta pots into a garage or basement when temperatures consistently dip below freezing.Pots made from terracotta, ceramic, and plastic are all prone to cracking in winter thanks to the freezing and thawing of moisture in the soil. As temperatures dip to 32ºF or below, any water in the soil will freeze and expand, which can cause the pot to crack or break under pressure.
