Some grow things by the other senses'....
By touch, some
plants like a lambs ear....
It's so soft and fuzzy to the touch..
By scent, sweet smelling
flowers...
lily of the valley's once planted are almost self suffient and no care...
And you should start planning now, how to get around, or where you want to garden...
If out in your land, you should put up a walk path, that will not let you fall.. or slip or stumble and have a handy railing or string to pole arrangement that as you walk you can guide your hands over and know your way..
Nothing like grass to slip on, or have a mole dig a hole up thru.. catch a cane tip on ...
and also with the other senses' you should have things you can hear along your path..
Like hearing, like a waterfountain or windchime, so you know just about where you are..in the garden...
or if you do garden on your porch a series of pots/containers, in a row at certain levels you can agree with and feel comfortable with..
I know I have seen tools, like a trowel, that has engraved depths to it too, so you can put your hand/fingertips on them and be able to know the depth you are digging with....
Oh there is soooooo many ways to still garden...
don't give up... and learn now, just in case for later...
Like when pruning, feel your way on your
plant now, with your eyes completely closed.. and feel how they feel... and then open your eyes, then figure out where you'd cut or prune.. and feel that out again... and get used to how it feels...
