Big Dreams Small Spaces BBC2, 8pm
Monty Don returns to help more amateur horticulturists transform their small or average-sized plots into something extraordinary. In Salisbury, newly engaged couple Glenn and Zoe want a new garden to produce flowers for their wedding, but their sloping plot seems completely unusable. Monty has the ideas and plenty of enthusiasm, but can they get the planting done in time for the wedding? In Barnet, he gets to work on an overgrown allotment that owner Nighat wants to use as a site for keeping bees, as well for growing fruit and vegetables.
