Put an ad in the paper and give them away.....put an ad in free cycle and give them away.
I really think it's criminal to kill plants or bulbs that others may be spending money to buy.

I can relate to Jo Ann. They have taken over a large section of garden and need to be dug now while dormant. Digging in a heavy clay hillside in the heat of summer is difficult, especially for the older gardener. Al

I'm absolutely positive that someone will be glad to come and dig them if you place your ad in Free-cycle.
I know that I would do and not for the reason of saving some money or greed to have another 200-300-500 of daffs in additional to about 1000 of my own, but just for the reason of not let them die by such miserable death instead of bringing the joy to other people for many-many years from now.
BTW, you may contact your local schools, churches, library or parks and recreation centers in your own or neighboring towns and they might accept your 'daffodil donation'.
Couple of years ago someone in our town donated his extensive 'astilbe and hosta collection' to YMCA and we dug, moved and planted it for the two weekends on a row, but saved it from the buldozer.

All in one go is too much but perhaps some at a time might be feasible. If you planned on doing a patch - like doing square foot gardening - then you can get through a lot without ending up wincing.

And if you have two or three gardening friends or acquaintances - preferably with links to gardening groups or plant fairs or similar disposal routes - then that may be safer than an open slather invite.

The last thing you want is precious potted plants wandering away with the bulb diggers.

So my first choice would be for you and some reliable friends to get together to do the job in patches - interrupted by coffeee and cookies; or enlist safe help through the local garden club or a service group.

After all - even if you do spray - the bulbs will still be there and may well return to the following season. If they're out of the ground then you can refresh the soil and plant new things.

Wish I lived close by I would gladly come and dig some up. I've been wanting some. Like vetivert8 I hate to see them go to waste.

I’d love to know how that garden is doing now! I’ll bet that no matter what was done, the daffodils will win 🤪

Why can't you just get out the lawn mower early and mow them down over and over? Or cut them down at soil level in March? That would be easy, without digging or poison. If they can't collect energy from their ugly grey- green strap leaves, wouldn't they get weaker and stop multiplying?

Daffodils are so common and so cheap, lazy gardeners would never want to dig them up at all, digging up dormant bulbs is hard work, just buy them in box stores. Why would more serious gardeners want to dig up common Daffodils unless it was a rare variety?
