Welcome to Garden.org,
@applevalle !
You will find plenty of company in "having to learn new ways of doing gardening chores" here ! Even without specific health problems, many (perhaps the majority) of us here are getting older and finding we need to make some modifications in our gardening routine ! So, pretty much everywhere you go here you will find someone referring to the fact that they apparently are no longer superwoman -- but you may find this thread, in particular, or interest:
The thread "For Physically Challenged Gardeners" in
Sandbox forum
I hope you enjoy the site -- I'm looking forward to "seeing" you around!
