While I do not have the opportunity to take upon this myself, I'd like to encourage you to think about landscaping your property - "green" style. The best way to go about this is to plant native species in your yard. "Native" refers to a plant or tree indigenous to your particular area. The major plus side of planting native species, the best part is that they take care of themselves! You dont need to plant any special type of soil, or water obsessively (i.e. waste water). Native plants will thrive in the soil you plant them in, as well as the work well with weather conditions for that region of the country. In other words, planting native species in your yard will save you time and save you money with the decreased water expense. Plus, native plants also work with and enhance local ecosystems.
Not only am I talking about plants, but also about the grass that covers your yard. Many people plant the common blue Kentucky grass, which, unless you live in that native region, requires a lot of watering during those hotter months. This amount usually ranges around 3 inches of water (again, depending on your area) to keep your grass looking good. That's a lot of water!

Also, if you have a nice big backyard, consider creating your own composting bin. This website offers numerous plans for different types of composting bins, but keep in mind that they do not have to be a complex item that requires a construction crew to build. It can be as simple as taking some steel fence wire, looping it around and attaching it to make a circle, and then adding your compost. All that would be needed for tools is a wire cutter. You can build more than one to create a "compost fence" or a cool fort for your kids!
In addition, if you have a canine friend living with you, there are ways to compost your pup's waste to save space in landfills. City Farmer has a lovely website on how to create these bins, step-by-step, and other ways to dispose of your friend's fecal matter in an environmental friendly way.
I'm anxious for the day I will have a yard! :)
