Hi Betfam,
You don't say what your hardiness zone is or where in Montana you are located, but Montana has hardiness zones 2 to 5.*

Lily of the valley is hardy to zone 3 and most daffodils and tulips are hardy to zones 3 through 5 depending on which ones you have.* I'm wondering why you need to store them out of the ground for the winter.* If your zone is too cold for them to be in the ground, it's my understanding that you would treat these plants as annuals.* I suppose you could try storing them in mesh bags in the refrigerator but you can't have any apples or pears in there as those fruits off-gas and will destroy your bulbs.

When weeding, the best way to make sure you are removing a weed and not a valuable plant is to pull on it. If it comes out of the ground easily, it is a valuable plant.
