Container plants are an easy and convenient way to begin gardening or add to your landscape. But not all container plants are created equally, so it's wise to learn what to look for before you head to your local garden center. And consider your long-term gardening goals. Are you willing to spend more on older, bigger plants in order to get an established look quickly? Or are you able to wait younger -- and more affordable -- plants to fill out? Either way, take a few steps to make sure you're buying healthy container plants and you'll soon have a lush and beautiful yard.
