:) Hi Ivan, welcome!!!
I agree on the rotovating, having done this on a previous plot!!!
Best to mark out a plot, dig and weed by hand. Cover the rest with black plastic, old carpet or underlay. Leave until weeds, grass have died. You can work on extra bits as before when you get time.
My friend gave me good advice and so have the guys on hereits, Do one area well, clearing it properly or you will get double/triple the weeds next year.
Rotovators are brilliant to use once you do the worst by hand.
Good luck and stock up on plasters for the blisters and beer so you can get plastered when you are knackered.
