The only way I have been able to deter the rodents is to cover my plantings with wire mesh (Chicken wire). If they are grouped in a small area, cover the entire area with the mesh and secure the corners with "hairpins" made of stiff wire. Add a light covering of mulch to hide the wire.
If the bulbs are scattered, cut sections of the mesh about one ft² for each bulb. The stem of the plant will have room to emerge through the mesh, but if one or more have a problem, just clip the mesh to avoid conflict.
Once the soil settles, the Chips will usually lose interest.
After the Lily's die down in the fall, you can remove the wire mesh or leave it, as you wish. They won't bother them next year, as long as the soil is undisturbed.
Good luck!

I am going to try a rodent repellant called Shake Away (for rats). Chipmunks are rodents, too; I will post my results for all to see.

Put a little blood meal in your garden. It keeps all the critters away.

I bought those 50% lily bulbs (5 per bag) at Lowes on Hwy. 92 in Woodstock about 2 weeks ago, and planted them immediately that afternoon. When I opened the bags they looked so dried I wasn't expecting much and so far nothing has sprouted. (I bought Casablanca, Stargazer and Arena types) I hindsight, they probably weren't worth it, but I haven't given up on them quite yet. Even one of each type growing would make it worthwhile.

Did you soak the bulbs prior to planting? I always do that. I planted mine, again, on Sunday. Please post if you have success.

I tried something different to protect the bulbs and so far it seems to be working: I cut 2" diameter PVC pipe into 2" lengths. After planting the bulbs and filling the holes, I pushed the 2" length PVC half way into the ground. All look undistrubed. I'm thinking it limits the chipmunks abiliy to dig.

Hey, if this works, maybe I ought to patent the idea...ha.

Oh Boy! Do I ever feel your pain! I'm in east-Bartow County, not far from you...wonder if our chipmunks are from the same, bulb-root deranged chippy family...cousins, maybe?

I planted three new perennial beds this spring and was so thrilled to see them all taking off, really well...until the dreaded chipmunk invasion. I had a phlox growing in a pot on my deck that somehow, mysteriously turned into a bare, shortened stem. I found the culprit trapped between my window and the screen I had removed earlier. Several of my perennial plants have been dug up and of course, they died, but I was determined to win the battle. Not sure I have yet, but I'm working on it.

I poured blood meal around one of the beds and scattered moth balls on all three. They are still digging, but not quite as much. I also bought a plastic snake and put in one of the beds, and oddly, that bed seems to be less disturbed than the others. Of course, my son saw the snake from a distance and freaked, because he thought it was real!

The ones on the swimming pool of death might be a little icky, but scroll down quite a way and you'll see the posts by AGardenStateofMind, GoingNuts, and a couple of others are quite humorous...if you can't beat the little devils, well...gotta laugh!
