Do they actually stay there longer than a plant tag?
The squirrels don't steal them?

Crows steal my shiny metal tags, and my dogs chase off the squirrels, so I can't answer your question about squirrel thievery. I doubt the wooden tees last longer than 2 seasons. Plastic will last longer unless you step on them. I use them mainly to mark the spot until i can get a good metal marker in place. At times, I've resorted to using plastic silverware to mark bulbs, too. The black plastic doesn't look quite as bad as the white. I've written the name of the bulb on the end I stuck in the ground and it actually stays readable.
Hope that helps...........seems like I've tried everything and I still occasionally fork a bulb.

I plants my bulbs in clumps and place a circle of small rocks around the clump...........I still occasionally dig some up.

Forgotten about the plastic ware. Have transparent knives and spoons from summer when I used them as temporary name tags for plants I was shipping for sharing. Think I can remember where most of the bulbs are and will try that here in the next few days. Thanks, Cindi!

Thanks
Yeah I think the bulbs shift or something even when marked

The daffodils spread far and wide. Markers for them only indicate a starting point!
A bulb I really struggle with is naked ladies. I swear those travel yards from where i plant them, and since they are not in sync with other bulbs on growing/blooming times, I forget to mark them.
