It All Starts with Soil
Depending on where you live in the Devon, your soil can be heavily acidic or alkaline. The soil can also have large amounts of clay or iron. The point is no matter what landscaping or grass you are planning on growing, your soil has to cooperate. In order for your soil to work as well as possible, you need to have it tested. Your soil might be perfect or it might just need some nitrogen. Soil engineers can test and analyse soil from different points in your yard to help your yard perform at its best.
Utility of Landscaping
What you need to understand about landscaping is that it serves more than just an artistic or aesthetic purpose. Landscaping is functional outdoor art, but it can also serve as a vehicle for privacy; landscaping can exist to attract certain insects or birds to your home; landscaping can be used to cover up your foundation that sticks out from the bottom of your siding, among other things.
Good landscape architects and landscape designers are trained to utilize your landscaping for whatever end you desire (security, privacy, etc) with a design that is pleasing to the eye and to the neighborhood.
So think about what you are trying to accomplish with your landscaping. If you are interested in attracting butterflies or keeping neighbors from peering in, keep this in mind so that your landscaping can serve this dual purpose.
Maintaining Your Landscape
After you have had your landscaping designed and installed, there is an issue of maintenance. You will either need to maintain your yard and landscaping yourself or you can hire a landscaper to do it for you. Either way, early spring through early fall, there will be steady work on your landscaping to keep up with the Jones's. But it is good work. You will be outside, sweating, and getting your hands dirty trying to get that green thumb.
