Never kill a plant again (well okay, maybe we can't promise that). Our classic self-watering planters come with a built-in reservoir and drip tray to prevent both root saturation and drying out. Each one is made from 100% recovered plastic waste, making them highly durable, outdoor safe, and good for the environment! Using the self-watering feature: Give your plant a good soak after planting to fill up the reservoir, then water to your plants needs as usual. It's as simple as that! Notes: - Sizes are nominal and may vary among our different styles of planters. Please send us a message if you need exact dimensions!
