Daffodils are one of the most long-lived plants in the garden. They reproduce through side bulbs, and after a few years they may produce more leaves than flowers. Then it is time to divide the "onion cake". Lift the whole clump, divide the bulbs and replant them with 10 cm between bulbs. Daffodils should be planted in early autumn, preferably in well-drained and slightly moist soil, about 15 cm below the ground.
