In the fall of 2014 I planted tulips every 6 inches around the rose garden.
Last spring we had almost every one come up and bloom - they all came up,
3 or 4 didn't bloom . I'm still waiting for them to come up this year ...
and it's way late . So today I dug up where I know i planted two of them -
and there's no bulb , nothing . No tunnels like maybe the ground squirrel or
moles or something got them , just nothing there . I've never noticed any
digging like squirrels got them , no tunnel bumps like moles/voles/ ground
squirrels often leave but they're gone .
Anybody have any theories on where they went ?

Without knowing what zone you're in, your topography, and what
critters habituate your property it's not really possible to say, all
one can do is guess... I'd guess rabbits... deer will suck up bulbs
too... really only daffs are safe. I fence my tulips but I don't have
many because voles will eat them, only thing saving my tulips are the
feral cats I care for.
