Growing tomatoes and patio strawberries

This week's show is a bulging barrowful of edible gardening advice. RHS Horticulturists Guy Barter and Lenka Cooke discuss how to grow tomatoes, recommended tomato varieties and ways to beat blight. The Gardening Advice team gather to debate the best strawberries to grow on a patio and how to get rid of scale insects on a lemon tree. Plus seasonal gardening jobs to do in March.
