Monty Don travels around the country helping amateurs to create the garden of their dreams. In this episode, he is asked to rescue two nightmare outside spaces. In Salisbury, newly engaged Glenn and Zoe want a brand new garden and most of all they are desperate to produce flowers for their wedding. Currently, their steeply sloping garden is completely unusable. Armed with advice from Monty and plenty of enthusiasm, they set about creating the garden of their dreams. But with their wedding looming, can they get the planting done in time? A trip to Sarah Raven's garden in Sussex might provide them with the inspiration they need. Meanwhile in Barnet, Monty gets to work on an overgrown allotment which is being turned into a site for keeping bees. The owner Nighat wants to grow her own fruit and veg as well as bee-friendly plants, but currently all that's there are weeds and overgrown trees. After a trip to a stunning forest garden, Nighat is determined to turn this site around. But can Monty persuade her to leave her worries at the garden gate and just go for it?
