I am sorry for this delayed reply to your gardening question. We are transitioning to a new Q&A system and your question was unfortunately lost in the transition. I have discovered it now and hope this reply is not too late to be of help.
Pathways tend to become compacted and low spots that hold moisture. You can place some stepping stones along that path which you could take with you when you move. Another option is to get shredded power line trimmings or other cheap to free chipped wood material to place 6 inches deep along the path for an all weather walkway. If you can trim the trees some to increase the brightness of the shade you may get better results with grass growing, but it will never grow where there is foot traffic.
Thanks for the question. Please stop in again soon!
