Vertical gardening is the way to grow! You can make the most of your garden space by growing delicious vegetables and fruits and colorful flowers up on a trellis, on garden netting, in a tower of pots, and over garden structures, while enjoying the benefits of easier maintenance, healthier plants, effortless harvesting, and higher yields.The biggest mistake gardeners make in planting a garden is starting too big. After they dig the soil in a large garden plot and plant a traditional horizontal garden in long, straight rows or large raised beds, summer days get hot and humid, encouraging a forest of weeds and creating a daily need for plant watering.
