This week we're at RHS Wisley where we meet garden managers Peter Jones and Emma Allen who share seasonal horticultural highlights and tips on what to do now. The Gardening Advice team deal with a bulging post bag of queries on a range of topics including lining hanging baskets, feeding tomatoes, summer lawn care, growing plants in pots and more. Plus we have joyful garden memories from designers Sarah Eberle and Chris Beardshaw.
