Oct

Autumn is a great time to divide summer-flowering perennials, after they've finished their display. Carol Klein selects a large clump of day lilies (Hemerocallis) and explains how to tell if it's overcrowded. By dividing the clump, you'll not only reinvigorate it, you'll also get new plants for free. In this short video clip from Gardeners' World, Carol demonstrates how to dig up and split a mature clump of perennials, then prepare the resulting smaller sections ready for replanting around the garden.
