Check out this Gardeners’ World video to find out how to lift and divide pulmonaria to increase your spring display. Monty Don shows you two easy techniques. First, he simply pulls a clump into two parts, to replant straight into new sites. Then, he shows you how to split a clump into as many small new plants as possible, then grow them on in pots until they’re big enough to plant out in spring. Watch now and choose which method you prefer.
