You may have enjoyed those beautiful daffodils and tulips earlier this spring, now the flowers are gone you may be tempted to cut back the foliage… But wait!
Even though the flowers may have stopped blooming, they are still using their leaves to create energy for next year’s flowers. The foliage will slowly turn yellow, absorbing sunlight creating energy for production of sugar, which is used to create flowers in the spring and store energy to withstand the winter. If you cut the foliage back too early, you are depriving the plant of a source for energy.
So, you can snip the spent flower, but you should not cut back the foliage until after the leaves have turned yellow.
