Leslie Land, on the fun site Next Avenue (check it out), has some workarounds for gardeners with arthritic hands:
--Think of pain free days as money in the bank., This means everything you do on pain free days has a use cost--pet the cat, it may take away from pulling a weed.
--Give yourself a daily allowance. Bake a pie, you can't pick peas.
--Sort tasks into "must be done" and "must be done by me." Let someone else do the gardening tasks that don't require your artistic "hand."
--Even if you don't have a lot of delegatees, keep a list of tasks for when a likely helper enters the zone.
--Or hire help. Forget the teenage looking for money--that person is rare these days. You may need to go to TaskRabbit or Craigs.
--Preheat your hands. In early spring, when the garden is cold, wear rubber gloves and soak in hot water for five mins or use a wax machine.
--Ration hand use by a kitchen timer. Work a certain amount of time--the rest will wait.
--Grab things with your whole hand--not just your fingers, Lift a flowerpot--for example--but support it underneath.
--Keep your tools sharp--less pressure must be applied.
--Take pix with a smartphone--not notes with your hands.
--Bathe your hands in sunshine. Sit for a few minutes.
