I’d go with mulching them and marking them. Could be they’re just late coming up, too. My daffodils and hyacinth have about 1-1/2” of green shoots coming out of the ground, but I’ve never noted when I’ve seen them in past years, so I don’t know if they’re early, late, or what. I’m not much of a gardener. ;o)
The daffodils just aren’t blooming like I thought they would.
But I like your plan. And not doing the Christmas show I’ll have time to remulch and feed them over the winter.
(see how I worked that in that I’m still not doing the show?)
