Tends to dry out quickly, which makes it ideal as an indoor pot for drought-loving plants and Mediterranean herbs like rosemary, sage, and thyme. Glazed terracotta doesn't dry out as fast. Freezing temps can crack or weaken terracotta when used outdoors. Best stored empty through winter in cold regions.
Lightweight, durable, and affordable. Bright colors add zing to any setting, or select traditional terracotta tones. With outdoor pots, direct sun heats black plastic, which can harm roots in hot climates. Also consider alternative plastic containers, like tubs, bins or buckets. These work well both indoors and out.
