That's a lot of bulbs. I've been enjoying all your pictures. You've created such a beautiful display!

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.

I think G. maccrorrhizum might be too dense for daffs. It's fine near hostas, you'll just have to pull it back if it gets pushy. It's a great plant.

We have have many rainey days here but lots of sunny ones also :-)) What I do is snap off the seed head part of the stalk on the daffs every few days and or cut (at the very top) off the dying spent flowers. In that mixed daff collection pictured wave after wave of flowers opens. As some finish, others start. So deadheading keeps the mixture looking good even now and they started weeks and weeks ago. In fact they started the very, very beginning of April. Here is how they look now with the last wave flowering and I have cut off all the spent blooms leaving the flower stalk. Here you can see the daylily folliage running in front of the tulips. It should make the tulip folliage much less noticable. Again, as soon as the tulips drop their flower pedals, I will snap off the very top of the stem which has the seed head. I just leave folliage, don't much worry about it. I find it's gone on it's own soon enough and there is always something else going on in the garden to look at. In the two belgium block mini terraces running accross which is were the daffs are, I plan to plant zinnias for summer long color. I will use seedlings and just plant them between the daffodil folliage. I am sure there will be some lang time there between when the daff flowers are all gone and I get my zinnia seedlings in. I haven't even startted the seeds yet as it has been too cold. But I have been growing zinnias in that front section for the past two years. This was before I put in the belgium block mini terraces late last summer. That then allowed me to plant the area in bulbs last fall as planned.
