Do Gophers Eat Tomato Plants: 7 Signs of Damage and How to Protect Them

Gophers are particularly destructive to tomato plants because they don't just nibble—they systematically attack the plant's foundation. 🌱 The root damage weakens the plant's ability to absorb water and nutrients, while their surface gnawing can create jagged edges on stems that invite pests.

I’ve seen gardens where gopher activity left tomato plants looking like they’d been pruned by a chainsaw, with no clear pattern to the destruction. Their burrows also create air pockets in the soil, which can cause plants to topple over during storms or even collapse under their own weight.

What makes this especially frustrating is how quickly gophers can devastate a garden. A single gopher can consume up to 10 pounds of plant material daily, and since they’re most active at dawn and dusk, you might not even notice the damage until your tomatoes are already struggling.

The key is to act fast—once they’ve established a burrow network, they become much harder to dislodge.

How gophers damage tomato plants and gardens

Gophers primarily attack tomato plants by targeting the roots and underground stems, which is their most destructive behavior. Their sharp, chisel-like incisors allow them to gnaw through ¼-inch thick roots with ease, severing the plant's connection to vital water and nutrient sources.

This root damage often appears as jagged, clean-cut wounds rather than the ragged tears caused by other pests. 🌱 The plant may initially show signs of stress like yellowing leaves or stunted growth before eventually wilting completely if the damage is severe enough.

Surface damage occurs when gophers move above ground, often during their foraging at dawn or dusk. They'll gnaw on stems just below the soil line, creating a 1-2 inch diameter wound that can cause the plant to topple over.

Their burrowing also creates a network of tunnels that destabilize the soil, making it more prone to erosion and disease. I've observed gardens where tomato plants literally collapse into the newly formed tunnels, leaving behind a trail of broken stems and exposed roots.

The soil around affected plants often has a spongy texture due to the air pockets created by their digging.

One of the most insidious effects is how gopher activity increases disease susceptibility. The disturbed soil allows harmful pathogens to thrive, while the open wounds on stems provide entry points for fungal infections.

Tomato plants weakened by root damage often develop early blight or verticillium wilt more readily than healthy plants. The combination of physical damage and increased disease risk can turn a thriving tomato garden into a wasteland within just a few weeks of gopher activity.

Identifying gopher damage requires looking for specific signs beyond just wilting plants. Check for freshly turned soil mounds (about 3-6 inches wide) near your tomato plants, which are their tunnel entrances. You might also spot chewed plant debris mixed with soil near these mounds.

Unlike rabbits that leave surface-level damage, gophers create underground chaos that's often invisible until it's too late. Their feeding patterns are particularly destructive to young tomato seedlings, which can be completely uprooted in a single night.

The timing of gopher activity matters too—spring and early summer are peak seasons when they're most aggressive. This coincides with when tomato plants are establishing their root systems, making them especially vulnerable.

A single gopher can create enough damage to reduce a tomato plant's yield by 50-70%, and in severe cases, completely destroy the plant. The key is recognizing these signs early and implementing protection before the damage becomes irreversible.

Effective gopher-proofing strategies for tomato gardens

Start with a hardware cloth barrier—this is the gold standard for protecting tomato plants. Use ¼-inch mesh (small enough to block gophers but large enough to allow water drainage) and bury it 12-18 inches deep around your garden beds.

For individual plants, create a cylinder by bending the mesh into a tube and placing it around each tomato plant at planting time.

The key is to overlap the edges by 6 inches to eliminate any gaps where gophers could squeeze through. 💫 I’ve had the best luck with galvanized hardware cloth because it won’t rust over time, unlike chicken wire.

Raised beds are another excellent solution, especially if you’re dealing with a persistent gopher population. Build beds at least 12 inches deep and line the bottom with hardware cloth before adding soil. This not only protects roots but also improves drainage and soil quality.

For existing gardens, you can create temporary raised sections using wooden frames or even large pots sunk into the ground. Just make sure the bottom is fully covered with mesh—gophers are skilled diggers and will chew through weak barriers.

Natural repellents can complement physical barriers, though they work best as part of a layered approach. Castor oil-based repellents are particularly effective—mix 2 tablespoons of castor oil with 1 teaspoon of dish soap and 1 quart of water, then spray around your garden (avoid direct contact with plants).

Reapply every 7-10 days or after heavy rain. Another option is predator urine (like coyote or fox urine), which you can find at garden centers. The strong scent deters gophers, but you’ll need to refresh it frequently since rain washes it away quickly.

Don’t overlook the power of habitat modification. Gophers prefer loose, easy-to-dig soil, so amending your garden with compost and organic matter can make it less appealing.

Planting gopher-resistant cover crops like clover or alfalfa around your tomato patch can also help—these plants are less palatable and may distract gophers from your tomatoes. Additionally, keep your garden area well-mulched with coarse wood chips; the rough texture is uncomfortable for gophers to dig through. 🌱

For a more aggressive approach, consider trapping. Tunnel traps work best—dig a hole near a fresh gopher mound, place the trap at a 45-degree angle with the entrance facing downward, and bait it with apples or sweet potatoes.

Check traps daily, as gophers can die quickly if left too long. Remember to wear gloves when handling traps and dispose of captured gophers humanely and legally in your area. Trapping is most effective in early spring when gopher populations are still small.
