If you have a small area of lawn like I do, or if you are tired of cutting the grass once or twice every week have you ever thought of putting in ground cover instead? You could carpet the ground entirely with low growing, easy care plants, known, naturally enough as ground covers.
You can use annuals as temporary ground cover – nasturtiums are excellent – but the best ground covers are spreading evergreen perennials or dense, low growing shrubs. Flowers are a feature of many, but far more important is the ability to make a carpet dense enough to smother weeds without growing too tall – ankle height is about right.
A good ground cover needs to be presentable all year; to need little in the way of trimming or spraying; and to be easy to propagate to cut down on cost. It is possible to weave patterns with several species, but the stronger will tend to crowd out the weaker, and simplicity usually looks better anyway. Ground covers cannot be walked on.
Prepare your ground cover bed as thoroughly as for any other plant, plant at the appropriate season, and mulch at once. The last thing you want is weeds getting in between the young plants. If you like, you can plant some low growing annuals between your permanent plants – and they will remind you to water and fertilize. Ground covers may be low, low maintenance when they are established, but when young they need care.
Here are some ground covers for both sun and shade:
