STEP BY STEP Divide pulmonarias

PULMONARIAS are valuable ground-cover plants with pretty spring flowers and speckled foliage. To get more plants with the exact leaf markings of the parent, lift and divide clumps now. This will also reinvigorate the original clump. The new plants will be ready to plant out by midsummer.

Use a knife to cut off small sections of the clump, each with several roots and leaves. 2 Trim large old leaves in half and cut back any unruly roots. 3 Pot them up into multi-purpose compost, water in well, and grow on in a cold frame or sheltered spot in the garden.
