What planters can stay outside in winter?
Fiberglass planters are lightweight, durable, and built to handle harsh winters. Fiberglass planters are a winter workhorse. Unlike terracotta or many ceramics, they don’t easily crack when temperatures dip below freezing. The slightly flexible structure allows them to expand and contract with temperature changes. 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.
How big should outdoor planters be?
Generally, using three or four plants in 10 to 12-inch planters, four to six plants in 14 to 16-inch planters and six to eight plants in 16 to 20-inch planters will fill out containers nicely while allowing room for the plants to grow without excessive crowding. Container size should be in proportion to plant size. One rule of thumb is the container should be one third as tall as the plant. This is measured from the soil it is growing in to the plant’s tallest leaf. Although you can grow plants in any container, plastic containers are recommended.
