Not everyone has that perfectly flat terrain they would like in their backyard; some of them have a hilly backyard and determining what to do with that real estate is not always the simplest task. The good news though is that there are many different options to choose from that can make their yard look even better and use it as an outdoor living space.
For starters, the first thing you have to remember is that a hilly backyard is the most natural looking you could have and taking advantage of that is important. Use the high spots for landscaping but make the low points grassy if you can. However, if your property goes down hill towards the back, then use the high spots for grass and move the landscaping to the lower portions. At the same time, you will want some type of patio or porch. Sure putting in a patio is not a simple process with a hilly backyard, but if you make a porch you can definitely accent the beauty of your yard.
Do not forget to also include an area for cooking. Having an outdoor kitchen in your yard makes it the perfect spot for weekend barbecues. The view is just awe inspiring and it will be almost like going out to the great outdoors. Just because you backyard is not flat, does not mean there are no options for you. Many homeowners would prefer having a hilly backyard over anything else; you were just lucky in getting one.
So make the best of what you have and turn your hilly backyard into a wonder of nature. It will bring you closer to nature then you would ever expect. You can still add a garden or two, the only real difference is that you hilly backyard will need a little more planning ahead of time to make sure that it turns out the best it can.
In the end, you can only get out of your backyard what you choose to put into it. If you decide to look at the yard as an impossible task because of its grading, then you will never be able to truly enjoy it until you backfill and level out the entire property. Enjoy what you have; after all its yours .
