Where I cleared some of the brambles at the back of the plot I've planted a young Sweet Chestnut - Castanea "Marigoule". This is a Marron type giving one large nut per cluster rather than lots of small ones. And also a Juneberry - Amelanchier "Ballerina" which should provide fruits in July. Both of these from Cool Temperate Nursery, Cossall, Notts, as recommended by Ken Fern's Plants for a Future, situated round the back of Trinity Farm farm shop. The nursery isn't open to the public so if you plan on buying anything there you'll need to check the website and contact Phil to make an appointment.
