Jill, I got this idea about doing the trench at the bottom when it suddenly hit me that I had room at the bottom there that was otherwise wasted. And I bet I could get a really lot of daffs along in there. As to putting them between, I have thought of it. But now before they grow, it looks like there is room but later after they leaf out all the room betwen them seems to dissapear. Still, I keep thinking about it. Remember all this is on a rather steep slope. I just want it to look pretty. In the summer when the daylilies bloom it looks fabulous but right now it looks ratty and in need of something blooming along there for spring color.
That method, you described were you dug a hole beween plants and stuck about 5 bulbs in is one I was using in another daylily bed in my backyard. I put in 50 tulips that way, 5 in each hole. I just dug holes betwen daylily clumps. After I was done I realised I could have used lots more bulbs as I had lots more spaces left. So will just mark were I already put some this spring and get more bulbs to add in the fall there.
I just keep on working on the gardens here and am really focused on adding lots and lots more bulbs!
