I love this idea! It is truly the best of both worlds for gardeners. It is the ease of container growing with the benefits of plants being a part of the landscape. I find container growing is easier to maintain. You could simply pull out the pots for watering and fertilizing, without the hassle of moving a hose, or wasting water in run off. I like the idea that I can control how the plants grow in my garden. It allows for maintaining garden designs.
