Wrap each young trunk in a 24-inch-tall cylinder of 1/4-inch 23-gauge galvanized hardware cloth, cut 20 inches wide so it closes to a 6-inch diameter with a 1-inch overlap. Bury the bottom 4 inches, tie the seam every 4 inches, and brace it to one stake so it never leans on the bark. In snow country, use the full 48-inch roll height so the top stays well above the deepest drift.
Rabbit or Vole: Read the Bark First
The fix is the same cylinder, but the damage tells you how tall and how deep it has to be.
| Sign | Rabbit | Vole (meadow mouse) | Pocket gopher |
|---|---|---|---|
| Where on the trunk | From the soil line up to about 18-24 inches, higher when standing on snow | From a few inches below the soil line to a few inches above | Below ground, on the roots and root crown |
| Tooth marks | Broad, clean cuts; small branches clipped at an angle | Small irregular patches, about 1/8 inch wide | Bark stripped under the soil |
| When | Late fall through late winter | Year-round; worst under snow and mulch | Year-round |
| Fix | Cylinder tall enough to clear the snow line | Cylinder buried 4-6 inches, tight seam | Wire basket at planting, not a trunk guard |
UC IPM's vole pest note describes vole gnaw marks as about 1/8 inch wide and 3/8 inch long, in irregular patches. It also notes that vole girdling is usually above ground, while gopher girdling is usually below ground, and that damage under snow can run a foot or more up the trunk.
If the bark is gone below the soil line and roots are chewed, the trunk guard won't stop it. That tree needs a root-zone cage like the one in making gopher baskets for trees and shrubs.
The Spec
MU Extension's cottontail damage guide calls for an 18- to 24-inch-high cylinder of 1/4-inch mesh hardware cloth set into the ground around the trunk. For multistemmed shrubs, it calls for encircling the whole plant with hardware cloth or 1-inch wire mesh.
| Spec | Target | Why |
|---|---|---|
| Mesh | 1/4-inch welded hardware cloth, 23 gauge, galvanized | Stops voles and mice that walk through chicken wire |
| Height above grade | 20 inches minimum; full 44 inches where snow piles up | Rabbits feed from the snow surface |
| Buried depth | 4 inches (up to 6 inches in heavy vole ground) | Voles dig under a guard that sits on top of the soil |
| Diameter | About 6 inches for a 1- to 2-inch trunk | Leaves 2 inches of air between mesh and bark |
| Seam | 1-inch overlap, tied every 4 inches | No gap for a vole to squeeze through |
| Brace | One stake, tied at the top and middle | Keeps snow and mowers from pushing mesh onto the bark |
| Ties | 16-gauge galvanized wire or UV-rated cable ties | Easy to cut open when the guard is enlarged |
UC IPM adds three points this spec follows: bury the bottom 4-6 inches, brace the cylinder so it can't be pushed over or pressed against the trunk, and leave room between guard and trunk for growth.
Cut Sizes by Trunk Size
Measure the trunk 6 inches above the soil. Add 4 inches to that diameter, multiply by 3.14, add 1 inch for the overlap, and round up to the next full inch.
| Trunk diameter | Cylinder diameter | Cut width | Guards per 48 in × 50 ft roll (24-inch tall) |
|---|---|---|---|
| 1 inch (whip) | 5 inches | 17 inches | 70 |
| 1.5-2 inches | 6 inches | 20 inches | 60 |
| 2.5-3 inches | 7 inches | 23 inches | 52 |
| 3.5-4 inches | 8 inches | 27 inches | 44 |
Each 48-inch width gives you two 24-inch guards. For snow country, leave it whole and get one 48-inch guard per cut.
Materials and Tools
- Amagabeli 1/4-inch hardware cloth, 48 in × 50 ft, 23-gauge galvanized, the roll this cut chart is based on
- 16-gauge galvanized tie wire or 8-inch UV-rated cable ties, 6 per guard
- One stake per tree: 3/8-inch rebar or a 1x2 hardwood stake, 36 inches long
- Aviation snips, linesman pliers, a flat spade or drain spade
- Leather gloves and safety glasses
- Tape measure and marker
The 48-inch width matters. One cut down the middle gives two 24-inch guards with no waste, and a full-width piece covers deep-snow sites in one piece.
Install Sequence
- Install in fall before the ground freezes. Rabbit and vole bark feeding peaks once green food is gone, so the guard needs to be in place before the first hard freeze.
- Clear the base. Pull grass, weeds, and mulch back 12 inches from the trunk. Leave bare soil inside the guard so voles have no cover.
- Cut the mesh. Wear gloves and glasses, because a cut roll springs back into a curl. Cut the width from the chart, then cut the 48-inch height in half for 24-inch guards.
- Trim the cut edges. Snip the cut edge flush with a cross wire so no wire ends stick out. Turn the top edge outward so loose ends face away from the bark.
- Dig a narrow trench. Push a spade straight down 4 inches in a circle about 3 inches out from the trunk. Rock the blade to open a slot without cutting roots.
- Set the cylinder. Wrap the mesh around the trunk, drop the bottom edge into the slot, and close the seam with a 1-inch overlap.
- Tie the seam. Tie every 4 inches from bottom to top. Twist wire ties to the outside, away from the bark.
- Backfill and tamp. Push the soil back against both sides of the buried mesh and tamp it firm with your heel.
- Brace it. Drive the stake 12 inches deep just outside the cylinder, on the side facing prevailing wind. Tie the mesh to it at the top and middle.
- Check the clearance. There should be about 2 inches of air all the way around the trunk. Reset the stake if the mesh touches bark anywhere.
Seasonal Maintenance
| When | Check | Action |
|---|---|---|
| After every heavy snow | Snow depth vs. top of guard | Pack snow down or knock drifts away from the guard |
| Monthly through winter | Fresh soil at the base, holes inside | Pull the guard, refill the hole, reset it 6 inches deep |
| Early spring | Leaves and mulch piled inside | Clean out to bare soil |
| Each spring | Gap between bark and mesh | Re-cut one size larger once the gap closes to 1 inch |
UC IPM warns to check guards often for voles that dug under or are hiding inside the cylinder while they feed. If you find fresh tunnels inside, pull the guard and reset it deeper.
Common Trunk Guard Mistakes
- Using chicken wire, which voles walk through
- Setting the guard on top of the soil instead of burying it
- Cutting the cylinder tight to the trunk so bark grows into the mesh
- Leaving wood chips or leaves packed inside the guard
- Stopping at 18 inches in a yard that gets 2-foot drifts
- Skipping the stake, so the first heavy snow presses mesh into the bark
- Leaving a 5-year-old guard on until it girdles the tree
FAQ
Can I leave the guard on all year?
Yes, as long as there are 2 inches of air around the trunk and you check it every spring. Re-cut it larger before the bark reaches the mesh.
Will 1/2-inch hardware cloth work?
For rabbits alone, yes. If you see the small irregular vole patches near the soil line, use 1/4-inch mesh.
What about white plastic spiral guards?
They work for rabbits on whips, but they sit tight against the bark and hide what is happening underneath. A wire cylinder lets air move and lets you see the bark.
