For the third successive game Norwich United scored a significant late goal to seal a deserved victory in Ryman League Division One North.
Liam Jackson's 94th-minute strike made it four consecutive wins for the Planters and condemned the determined visitors to the bottom of the table.
After a first half that saw a combative Mead line-up flounder on a strong home defence it was the hosts who had most of the chances, Shaun Wones' long-range shot the best, bringing a good save from Tom Wellham.
Adam Hipperson gave the hosts the lead six minutes after the break when he was fouled outside the box, the winger picked himself up to curl his 20-yard free-kick into the top corner.
The visitors responded six minutes later when a corner was bundled home at the far post by Alex Teniola, but the visitors' hopes were harmed by a straight red for Tom O'Connor for a foul on keeper Andy Wilton with 16 minutes remaining.
Just as it looked like the Mead had held on for a draw Jamie Speller put Tim Henery away down the right and the winger's delightful through-ball found Jackson who controlled and slotted home with a calm finish.
