Gardeners' World - 2010/2011 - Episode 20

As gardens reach their peak of summer productivity, Toby Buckland takes advantage of the abundance of new growth by taking cuttings while it is still warm, giving them plenty of time to grow strong roots before the onset of colder weather. He also has tips on how to keep cut flowers producing blooms for late summer and recommendations for the best varieties of heleniums to grow for an extended season of vibrant colour. Joe Swift has maintenance tips for green roofs and selects some hardy plants which will give year-round interest on top of any shed or log store. Alys Fowler is busy in the kitchen turning a vegetable glut into a feast for the winter by freezing, pickling and drying squashes, beans, courgettes, beetroot and herbs. At Glebe Cottage, while Carol Klein digs up her potatoes she explains the characteristics of the diverse potato family and how its members can feed us, add beauty to our borders and, in some cases, poison us. And Fergus Garrett, Head Gardener at Great Dixter, travels to the trial grounds at RHS Wisley to give us his expert opinion on the very best of the tried and tested flowers grown there that we might grow in our own gardens next year.
