Deer

Pest

Deer are large mammals that browse on garden plants when natural food sources are scarce or when they find your landscape particularly tasty. Their feeding habits can quickly strip foliage and flowers, leaving plants stunted or completely destroyed.

Symptoms by part

Leaves

Ragged, torn edges where the leaf has been ripped off rather than cleanly cut.

Stems

Broken or frayed woody stems, often with a jagged appearance at the point of breakage.

Flowers

Missing flower buds or blooms that have been snapped off entirely from the stalk.

Causes

  • Lack of natural forage in the surrounding environment.
  • Proximity of the garden to wooded areas or wildlife corridors.
  • Presence of highly palatable or succulent plant species in the landscape.

Could be confused with

  • Rabbit damage · Rabbits leave clean, angled cuts on stems because they have sharp incisors, whereas deer leave jagged, torn edges.
  • Insect defoliation · Insects leave holes or skeletonized leaves, while deer consume entire sections of the plant.

Treatment

  1. 1. Install physical barriers like tall fencing around the perimeter of the garden to block access.
  2. 2. Apply a scent based repellent to the foliage of vulnerable plants to discourage browsing.
  3. 3. Prune away any severely damaged or broken stems to encourage the plant to put energy into new growth.
  4. 4. Wrap young tree trunks with protective mesh or plastic guards to prevent rubbing damage.

Without chemicals

  • Erect a fence at least 8 feet tall to prevent deer from jumping over.
  • Use motion activated sprinklers to startle deer when they approach.
  • Plant deer resistant varieties that have strong scents or textures deer dislike.

Preventing it

  • Choose plants that deer typically avoid, such as those with fuzzy leaves, strong fragrances, or toxic sap.
  • Keep the garden perimeter clear of brush and tall grass to remove hiding spots.
  • Rotate the use of different scent based repellents to prevent deer from becoming accustomed to a single smell.

Season

The warm growing season is when they are most active, though they may browse year round if food is limited.

Spread risk

Moderate

Severity

High

When to act

Act immediately upon seeing signs of browsing to save the remaining plant tissue. If a plant has been stripped of more than half its foliage, it may be best to replace it with a more resistant species.

Questions people ask

Are there any plants that are truly deer proof?
No plant is entirely deer proof, as hungry deer will eat almost anything if they are desperate enough.
Why do deer rub their antlers on my trees?
Male deer rub their antlers against tree trunks to mark their territory and remove the velvet from their antlers, which can cause significant damage to the bark.
