Daffodils
Make sure to pop off the heads of your daffodils when they’re spent, so energy isn’t wasted on seed pods.
According to SophisticatedEdge.com, “Do not leave spent blooms on the plant. Deadhead as soon as the flower begins to wither. This will allow nutrients to concentrate on the bulb. Leave the greenery intact, as it is necessary to make food to supply to the bulb for next year’s growth. You can leave the foliage intact until it begins to yellow, approximately six to eight weeks later. If you cut back the flowerless foliage before photosynthesis has occurred, the bulb will not get enough nutrients and will likely die out.”
