Have limited time and space? WindowBox to the rescue. Their Belterra balcony window boxes are the perfect solution for those who don't have tons of space, but who still want the attractive look of real flowers to enjoy. That's because their specialized brackets allow for easy installation on railings, as well as directly to your home's wall. No time for gardening? Take that summer vacation without worry, since these planter boxes have WindowBox's patented irrigation system. The planter box itself will provide your flowers or greenery with fresh water and nutrients for up to 12 weeks; we recommend you water more often if conditions are warmer. That means you don't have to be a master gardener to achieve showcase worthy blooms. Each balcony planter features a removable liner, allowing you to plant on the ground or a potting table. You can also easily remove your flowers during storms or frost, without harming their vulnerable roots. This balcony planter is the perfect solution for those who love a beautiful garden, but who don't like gardening. Choose from both 20" and 31" models to accommodate your plant life perfectly.
