This is the month for unrully and dying daffodil foliage, and what we can do about it. The deep yellow foliage in the back is Lycoris. The daffodils in the foreground are 'Perimeter'. So don't cut it down until the tips start showing yellow. That takes about six to eight weeks after the bloom period.
Some people put there daffodil foliage into braids to make the foliage look better.
However, I do it two ways. In my larger daffodil beds that are never in front of my house, I leave it the way it grows and let it flop on the ground if it wants. No one sees it but me, and I only look at it to check my crosses. The other method I use is to plant companion plants in with the daffodils to mask the foliage. This picture is of the garden that I built last fall in the circle at the end of the driveway.
