Daffodil Culture: Daffodils should be planted to a depth of about three times the height of the bulb. I like to have about six inches of earth above a cluster of 5 or 7 daffodils planted in the same hole. After the bloom is finished, allow them to die back naturally. It is detrimental, regardless of what you read, to tie, braid or otherwise hamper the capillary flow of nutrients back into the bulb after the bloom is finished.
