Monty Don helps gardeners transform their outdoor spaces. In Teddington, Jennifer enlists the help of her sisters to create an Italian-themed garden in memory of their parents. She has great ideas and a budget to match, but growing citrus trees, olive trees and vines in a leafy London suburb is easier said than done. Will Monty be able to guide the sisters to a Mediterranean style success? Meanwhile in Billericay, Monty offers advice to Karensa who wants to turn an unkempt strip of back garden into a fantasy for her daughter, inspired by Lewis Carol's Alice in Wonderland. With a tiny budget but plenty of enthusiasm, she wants to create a chessboard patio, a heart-shaped lawn and a teapot water feature.
