How long should you leave daffodil leaves?
Accordingly, when can you cut the leaves off of daffodils?
Daffodil leaves should not be cut back until after they have turned yellow. Daffodils use their leaves to create energy, which is then used to create next year's flower. If you cut back daffodils before the leaves have turned yellow, the daffodil bulb will not produce a flower next year.
Subsequently, one may also ask, should I deadhead daffodils?
Deadheading is the removal of spent flowers. While tulips should be deadheaded immediately after flowering, it is not necessary to deadhead daffodils. Some gardeners do deadhead daffodils for aesthetic reasons as the spent flowers/seed pods are not attractive.
Though daffodils will not bloom twice a year, good culture will ensure the largest number of blooms each season. After the plants have bloomed, remove spent flowerheads, so the daffodils put their energy into making the next year's flowers rather than setting seeds.
