I won’t plant bulbs unless i have MoleMax handy. MoleMax is an organic product that repels all burrowing rodents. I like the granules. After the bulbs are all planted (yes, bone meal is a good idea) I’ll sprinkle the MoleMax granules over the area then water it in as I water the bulbs in. No burrowing squirrel, chipmunk, vole, skunk or woodchuck will dig in soil where MoleMax has been applied. It last for six weeks.
