There are multiple ways to start improving your curb appeal!
Mulch your flower gardens and around your trees, bring in dirt for around your home to help keep water from running towards your home, plant flowers, trim bushes, pick up leaves and sticks, and so much more.
I found this great tutorial on how to build a retaining wall around a tree; just click on the following link: http://handyowner.com/building-a-retaining-wall-around-a-tree/
This is a great way to clean up your front yard and appear fresh, clean, and new.
