Thank you Scroggin, Dovefromabove and Artjak.
I am going to the shops tomorrow to pick up some seeds and a few bits to get us started. A couple of local garden centres have kindly offered to donate some soil, equipment and wood to get the beds raised higher so our wheelchair patients can join in.
I hope to be discharged in a couple of weeks, so need to crack on. Thanks again for kind words, advice and support.
Very much appreciated by us all here.
