Put large containers and tubs on rollers or dollies so that they can be moved easily. It's pretty, portable and easy to care for by keeping just a few standard tips in mind. They can be moved around to dress up areas on a whim or used to fill bare spots in an established garden. When planting a container, throw in a variety of plants. Annuals, perennials, herbs, shrubs, small trees and vegetables all work well to create an interesting mix or even a mini landscape.
