This week we are celebrating the work of the army of volunteers who keep gardens up and down the country looking their best for visitors. Frances Tophill continues her vegetable trials at RHS Rosemoor in Devon when she plants out her allotment with the help of RHS volunteers and we visit the Bodnant Garden in north Wales to find out how the volunteers there guide visitors through the world-famous Laburnum Arch. Back at Longmeadow, we catch up with Monty's progress in his cutting garden and, now that plants are growing apace, he gets on with seasonal maintenance tasks in the Jewel Garden.
