Check these first
- Inspect the soil surface for small holes or disturbed mulch.
- Look for tunnels or runways in the nearby lawn.
- Check if the corms are missing entirely or just chewed.
Likely causes
Squirrel Activity
Most likelyHow to tell: You see small, shallow holes in the soil and missing bulbs. Squirrels are notorious for digging up freshly planted corms.
What to do: Lay down a piece of chicken wire or hardware cloth over the planting area. You can cover it with mulch so it stays hidden while the bulbs grow through the holes.
Voles
PossibleHow to tell: You find tunnels or trails in the grass leading to the bulb area. Voles often eat the corms from below the surface.
What to do: Plant your corms inside wire mesh baskets to create a physical barrier. Keep the surrounding area clear of tall grass and debris where voles like to hide.
When to worry
If you lose more than half your bulbs, you need to take immediate action with protective barriers. Minor digging is common, but total loss requires a change in strategy.
Stopping it coming back
Use wire mesh cages or chicken wire covers when you first plant your bulbs to keep them safe.

Questions people ask
- Are there plants that repel squirrels?
- Planting daffodils nearby can help, as squirrels dislike their taste. However, physical barriers are the only truly reliable method.
- Should I use repellent sprays?
- You can try them, but they wash off easily with rain. Physical barriers are much more effective for bulbs.
