storing Wood Hyacinth bulbs over the summer?

I have a berm covered with Wood Hyacinth (Hyacinthoides non-scripta) and they have bloomed and are now yellowing.

There used to be three trees on this berm that I have had to have cut and now I have three big ugly stumps, spaced the length of the berm. The berm has lady fern, casa blanca lilies and at least a hundred of these hyacinths. I can move the lilies and the ferns in the fall. I would like to dig up the hyacinths now as I can see where they are!

How would I store these bulbs over the summer? Am I better off just leaving them there now and hoping to find them in the fall? I want the stump grinder guy to come in the late fall, and then I'll have to bring in top soil and smooth out everything before replanting. I want to put a dogwood in the center and completely redo this berm.

Suggestions?

Hi Sterling: I have a small clump of wood hyacinth also. It is so cute. I didn't know it was a bulb. I just thought it was a regular plant. I suppose that if they are a bulb, and they are dying down, you can lift them just like a daff. If you have too many just let me know!

sterhill-- if the foliage is green you could try transplanting "in the green" right now into prepared holes.

Some bulb suppliers recommend that method for tyransplanting English woodland blue bells and I believe yours is a close relative of that.

The leaves are yellowing now - and I can "heel them in" in a area in the back just to hold them. But I'd like to just store them over the summer. I am hoping that a cool basement might work? I've quite a lot of them and would hate to lose them all...

I want to replant them on this same berm after all the stumps are gone and topsoil brought in so I really do not want to dig them, plant them and then dig them up again for replanting.

Everything has to be moved off of or out of this area to get these three stumps ground.
