Ah, but if you could get hold of one of those chairs with an ejector button - like they have for old folks (worryingly not much older than me!) then harvesting would be fun!
You wouldn't have to dig, but you might have to cover it with a net to catch your crop !! Or recruit a load of friends/allotmenteers with butterfly nets to catch your crop. That is, if you plant to plant a catch crop. Can't type here for giggling, must be the Baileys!
Seriously though, hats off for being enterprising - I'm only jealous that my OH won't give up our bed for me to grow parsnips in!
