Daffodils like to be planted in fertile, amended soil in a well-drained bed. Plant about 2 weeks before the ground freezes hard, usually after the first frost. Mix organic bulb fertilizer in the planting holes, but do not over-fertilize as that can overproduce green stems and lessen flower development. Plant bulbs two to five times their own depth, the pointy end facing the sky, preferably in full sun (though the part sun will do).
