The basic rules of design apply to exterior spaces just as they do to interior spaces. Perhaps the most important rules are those of proportion and scale. The various parts of the garden should work well with one another as well as with the overall space

Two other important considerations are symmetry and rhythm. Symmetry is created by balancing matching or similar features in the space. By repeating elements, whether plants, hardscaping, or decorative accents, you create a sense of rhythm.

Also don’t overlook the importance of focal points and accents. Focal points, whether they’re plants, decorative elements, or views, highlight specific areas of the garden. Accents add pops of interest throughout the space.

What Do You Want?
Before rushing to the nursery or lining up a landscape contractor, take the time to look at what you have and how you want to use your space. Start with a wish list. Write down all the ways you wish to use the space, even if they seem to clash. Your list might include a play space for the kids, a dog run, an area where adults can relax, a spot for grilling, a cutting garden, and fruit trees. Think about amenities such as an outdoor kitchen, fireplace, or water feature. Also think about the practicalities, such as where you’ll keep the gardening tools and the lawn mower.
