Resident experts Monty Don, Carol Klein and Ann-Marie Powell catch up on previous gardens and chart the progress and changes since last autumn. Monty Don travels back to the Merseyside garden of Annabel Waynne Jones. Last year the pair began work on the former coal yard, producing such spectacular results that Annabel opened her garden up to the public. Carol Klein returns to the Portsmouth plot of Gem and Drew who created a colourful shingle garden and a new allotment. Ann-Marie Powell travels to the steeply sloping Burton-on-Trent garden of Heather and Russell Eales. After removing a Leylandii hedge, building a shed and putting in a new pond, surely there is nothing left to do!
