Spring bulbs are among the most forgiving things you can grow. Horticultural experts agree that each brown, papery bulb contains everything it needs — roots, stems, leaves, and flowers packed into stored energy, waiting for the right soil temperature to burst into life. Your job, as experienced growers will tell you, is simply to get them into the ground at the right time and the right depth. Planting advice from specialists is consistent: most bulbs follow a simple rule of thumb — plant at a depth two to three times the height of the bulb itself. Tulips are the exception, with expert growers recommending a depth of 15–20cm to protect against disease and encourage them to return year after year. Timing matters too. Professional growers recommend September for daffodils, hyacinths, and crocus, and November for tulips — a delay that reduces the risk of fungal disease. But as even the most seasoned gardeners will admit, a bulb planted late is always better than one left in a bag. As the legendary plantsman Christopher Lloyd demonstrated across decades at Great Dixter, the most spectacular results often come from the simplest approach — bulbs, good soil, and patience. His famous drifts of naturalised crocus, left to colonise the meadow grass and multiply freely, remain one of the finest arguments for getting your bulbs in the ground and letting nature do the rest.
