Alan Titchmarsh and his team transform a concrete yard in Salford into a classic cottage garden for 87-year-old twins Rita and Betty Mills. Having lived in Salford all of their lives, the twins recently moved into their new bungalow for health reasons and have never wavered in devoting their lives to helping others, so Alan and his team work to transform their concrete patch of dismal cracked pavers and hard edges into a beautiful cottage-style outdoor space where they can relax.
