What should be done after daffodils flower?
Wild daffodil, Narcissus pseudonarcissus, and related cultivars are bulbous plants with a distinctive central corona. Narcissus includes many species, so plants called daffodils do not all share the same height or flowering season.
Reserve replenishment and leaves
After flowering, leaves photosynthesize and restore bulb reserves. Tying or cutting them prematurely can reduce this contribution. Maintain moisture during growth without sacrificing drainage. Natural yellowing marks entry into dormancy. Overcrowded clumps may flower less and can be divided at a suitable time. Failure to flower is not always fertilizer deficiency.
Placement and toxicity
Sunny sites or spring-lit positions beneath deciduous trees may suit them. Bulbs and other parts are not edible, and must not be confused with cooking onions. Handle sap and cut-stem water carefully. Species and cultivars differ in distribution and hardiness, so use identified stock. Nursery-propagated legal material is preferable to digging bulbs from wild populations.
