Understanding Rodent Behavior

To stop rodents from feasting on autumn sage, it’s helpful to know what attracts them in the first place Mice, voles and squirrels are drawn to certain smells, flavors and environments Here’s what brings them sniffing around autumn sage

  • Sweet nectar and tender plant tissues
  • Cover provided by dense foliage
  • Mulch and soil great for burrowing
  • Nearby fallen nuts and seeds to eat
  • Shelter under debris, woodpiles, etc.

Knowing these rodent preferences guides us in making the area less appealing.

Repellent Sprays and Dusts

Topical applications create an odor and flavor barrier on plants that rodents dislike. These are easy, effective options:

Hot Pepper Spray

The strong scent of chili peppers deters rodents. Mix cayenne pepper with water and dish soap and spray plants. Reapply after rain.

Garlic Spray

Blend garlic cloves with water, let sit overnight, then strain. Spray the stinky garlic liquid directly on autumn sage leaves and flowers.

Mint Oil

Pure peppermint, spearmint or wintergreen oils repel rodents. Add 5-10 drops per gallon of water and spray plants.

Rodent Repellent Dust

Sprinkle these along garden perimeters. The smell prompts rodents to avoid the area. Reapply monthly.

Physical Barriers and Deterrents

Prevent rodent access by making plants harder to reach and less inviting. Useful tactics include:

Hardware Cloth

Sink 12-inch pieces of hardware cloth into soil around plants to block digging and burrowing.

Wire Mesh

Cover exposed soil with 1/4-inch wire mesh secured with landscape pins to hinder burrowing.

Gravel Mulch

Use a 3-4 inch layer of pea gravel as mulch instead of bark to remove burrowing habitat.

Copper Foil

Wrap copper foil around plant trunks and stems. The metal gives rodents an electric shock on contact.

Metal Flashing

Place 12-18 inch strips of metal flashing halfway buried vertically around plants. Rodents won’t burrow beneath.

Motion-Activated Sprinklers

When triggered by movement, these shoot water to startle and scare off rodents from sage plants.

Discourage Rodents Through Garden Care

Altering the garden environment also persuades rodents to look elsewhere for food and shelter:

  • Eliminate piles of debris, wood and junk where rodents nest.

  • Keep the area around autumn sage clean of fallen fruits and nuts.

  • Thin dense ground cover plants so rodents have fewer hiding spots.

  • Remove heavy mulch right around the base of autumn sage plants.

  • Trim back foliage to reduce thick cover for rodents to hide under.

  • Fill any holes and gaps in fences where rodents enter.

When All Else Fails, Try Rodenticides

For severe rodent infestations, limited use of organic baits may be warranted to protect your autumn sage. Look for products containing castor oil, boric acid or diatomaceous earth. Follow all label directions carefully and keep pets away. Ideally, try to avoid toxins by sticking to natural deterrents first.

Common Pests & Plant Diseases

Autumn sage is easy to maintain with no serious issues. However, there are a handful of pests to watch out for, including leafhoppers, slugs, snails, rosemary beetles, whiteflies, and aphids. Maintaining dry conditions, using horticultural soaps, and the responsible application of pesticides can assist in controlling these pests.

Few plant diseases affect autumn sage, but crown rot can occur if the plant is struggling in poorly draining dense soil. This plant is especially resentful of wet winter conditions.
