At Vego Garden, we offer a wide range of raised garden beds roughly measured feet. You can think of it as the structure of the box without a bottom or top. We have designed our tallest kit of 32 inches that will provide you more soil depth for your plants, so more freely their roots will grow. In the deep garden boxes for vegetables, the soil will hold more moisture and require less frequent watering. If your time or space is limited, you might need to start with just one.
