We are doing spring over-seeding this time. Yes I know its not recommended or a popular choice, but given the tree shade we have in later half of the year, we are actually good candidates to do spring over-seeding while the trees are still barren and the weather is nicer! The soil/compost will not stink as bad as humid end of summer either, and if we dont have good success we have another opportunity in fall to double down on seeding. I am determined to have a lush green backyard in a couple of years!
