The best way to grow daffodils is to set them out as naturally as possible. Twenty-five years ago, I moved a lot of daffodils that had been growing at the edge of a flower bed in big clumps. They looked wrong, formally used in spaced clumps along the edge of a flower border, the bed filled with dahlias in summer. It was colourful, but looked messy to my eye.
Just after they finished flowering, I dug them up with a fork and loaded them into a wheelbarrow. I broke the clumps of bulbs into bunches of three or four bulbs, small enough to be planted behind a spade. When these groups were spread out over the new area, I could see how they might look in future years.
