Buy It: Keter Resin Elevated Self-Watering Plastic Planter ($151, Walmart) All you need to do is check the built-in water indicator. When you see red on the indicator, you need to drain excess water, and when you see green, you’re in the clear to water again. The planter is leak-proof, thanks to a handy drainage spout with a plug, which holds in excess water until you are ready to empty it. Because of this feature, you could use the planter indoors as well as outside wherever you don’t want dampness to collect, such as on a wooden deck. Not only will this self-watering planter keep your plants perfectly hydrated, but its raised garden bed (it stands about 30 inches tall) also eliminates the need to bend over or crouch, reducing strain on your back and knees while gardening. With a 31.7-gallon growing space, the container is large enough to plant several vegetables, herbs, or flowers together, but still small enough in size that it can fit on a balcony or porch. It only takes a few minutes to assemble with a screwdriver, and comes ready to fill with potting soil (you don’t need a liner). Whether you’re looking for a solution to gardening in a small space or weed-prone areas, this all-weather resin planter is super functional and will seamlessly blend into any other outdoor decor. If you’ve been looking for a new way to plant your favorite flowers or produce for summer, you’ve just found your new, go-to planter.
