How to Prevent Animals From Destroying Plant Bulbs

Bulbs are most vulnerable to animal damage just after planting. Although animal repellents may help to reduce bulb damage, a sure way of protecting bulbs is to make it impossible for animals to reach them. Two types of animals damage bulbs: digging animals such as squirrels and tunneling animals such as voles. A top barrier is sufficient for digging animals, but the whole bulb needs protection from tunnelers. Animals avoid daffodils, hyacinths, grape hyacinths, snowdrops, fritillaries and alliums, also known as ornamental onions; no protection is necessary when planting these bulbs.

Instructions

  1. Protection from Diggers

    • 1

      Plant the bulbs as usual, following the recommended planting time, depth and spacing.

    • 2

      Use wire cutters to cut a piece of hardware cloth to fit over the area where the bulbs are planted.

    • 3

      Remove the hardware cloth once the bulbs emerge or cover it with mulch and remove it in the fall after the foliage dies back.

    Protection from Tunnelers

    • 4

      Fill a plastic pot with garden soil.

    • 5

      Dig a hole large enough to sink the pot into the soil just below the soil level.

    • 6

      Place the pot in the hole. Fill in and firm the soil around it.

    • 7

      Plant the bulbs in the pot at the recommended depth and spacing.
