A solid choice for durability and function. This raised garden bed is strong, long and perfectly square. Reinforced with bracing boards on higher levels to prevent frost push-out or any disturbance from mowers or rambunctious children and pets. If you like an organized garden, you’ll appreciate how the bracing boards divide your garden into three separate planting areas. The stacked side boards give you lots of depth to grow both underground veggies like onions, radishes and carrots, as well as tall plants like tomatoes, corn or sunflowers. As shown, your 4' x 12' raised garden bed provides 48 square feet of planting area. You can redesign your garden at any time by assembling your available boards and brackets for unique designs. Tool-free snap-lock brackets make it simple to install. Your kit comes with everything you need except the soil and plants. Each modular kit includes composite boards, tool-free snap-lock stacking brackets and tool-free snap-lock 4-Way bracing brackets for 2,3, and 4 level beds. The insulating open-channel boards trap air, providing insulation to your soil. Keeps soil warmer in the Spring and Fall, and cooler in the Summer, so you can grow for an extended period. Stacking brackets allow you to install higher levels of your garden just by inserting the stakes into the brackets below.
