Got area we got to work on down spout. And will need it flat there..If i dig them up will I kill them? Sure hope Not.
Daffs are very strong. You can move them even if still green. You can move them, but I am not sure this will affect next spring's blooms. But it won't kill them.
You can dig them out now .. just be sure to keep the green leaves attached if you do. It gets energy for the following year from the leaves.
Your daffs will survive. In fact, this is a great time to see if they need to be divided. You may have fewer blooms next year, but just replant with the greenery, perhaps give them a little mild fertilizer, and you'll enjoy your daffs for years to come!
I have dug them before even with the blooms on them. It hardly sets them back at all that I could tell. Don't cut the tops tho.
They do not mind being moved most of the time. Keep the foilage if they are still green, divide them up. They will be right back in the spring. I thought I dug up all of them by my front sidewalk a few years back, and put them elsewhere. Ha. I have them around my sidewalk still, and in many new places. They need divided again...
