Do Groundhogs Eat Cabbage

If you’ve ever found your cabbage patch looking like it’s been through a shredder, you might be wondering who the culprit is. Do groundhogs eat cabbage? The answer, unfortunately for gardeners, is a resounding yes. These furry vegetarians find young, tender cabbage leaves and heads to be a particularly tempting treat. This quick guide will help you identify groundhog damage and give you practical, effective strategies to protect your garden.

Groundhogs, also known as woodchucks, are dedicated herbivores. Their diet consists almost entirely of plants, and vegetable gardens are like an all-you-can-eat buffet to them. Cabbage is a favorite because it’s succulent, easy to access, and often planted in neat, vulnerable rows. A single groundhog can wipe out an entire crop in just a night or two, leaving you with nothing but stems.

How to Identify Groundhog Damage in Your Garden

Before you start setting up defenses, it’s important to confirm your pest is a groundhog. They leave behind telltale signs. The damage often looks clean, like the plants have been neatly clipped. You’ll find missing seedlings, chewed leaves, and half-eaten heads of cabbage. Look for their distinctive, wide teeth marks on whats left of the plants.

Also, scout the perimeter of your garden. Groundhogs are burrowers. You’ll likely find one or more large entrance holes, about 10 to 12 inches in diameter, often near the base of a tree, shed, or fence line. Piles of fresh dirt beside the hole are a clear sign of recent activity.

Proactive Prevention: Keeping Groundhogs Out

The best strategy is to stop groundhogs before they get a taste of your cabbage. Here are the most effective long-term methods.

1. Install a Sturdy Fence

This is the single most reliable solution. A proper groundhog fence needs two key features:

It should be made of sturdy wire mesh with openings no larger than 2×4 inches.
It must extend at least 3 feet above ground and 1 foot below ground. Bury the bottom foot outward in an L-shape to prevent digging.

Some gardeners even add an outward-facing overhang at the top to deter climbers, though groundhogs aren’t the best climbers.

2. Use Raised Beds with Barriers

Raised beds can offer some protection, but they’re not foolproof. For real security, staple hardware cloth to the bottom of the raised bed frame before filling it with soil. This stops them from digging up from underneath. You can also attach fencing around the sides of the bed.

3. Apply Natural Repellents

Repellents can work as a temporary deterrent, especially when you first notice activity. They need to be reapplied frequently, especially after rain. Common options include:

Sprays made with cayenne pepper or garlic.
Predator urine (like fox or coyote) granules available at garden centers.
Strong-scented plants like lavender or mint planted around the border (though results vary).

Active Deterrence Methods

If a groundhog is already visiting, you need to encourage it to leave. Persistence is key with these tactics.

Make the Garden Feel Unsafe

Groundhogs are skittish. Use motion-activated devices to startle them:

Motion-sensor sprinklers are excellent. They give the groundhog a harmless but surprising blast of water.
Wind chimes, pinwheels, or even a radio talk show left on during the day can make the area feel less secure to them.

Keep the Area Clear

Groundhogs hate feeling exposed. Remove brush piles, tall grass, and wood stacks near your garden. This eliminates hiding spots and makes the journey to your cabbage seem much more risky for them. Mowing regularly around the garden’s edge helps alot.

What to Do About an Existing Burrow

Finding an active burrow on your property requires careful action. Never try to fill a burrow during the day, as you might trap young inside. The best time to address it is in late summer or fall, when young have left the nest.

Before sealing any burrow, you must ensure it’s empty. Loosely fill the entrance with soil or stuff it with newspaper. If it’s reopened within 24-48 hours, someone is still using it. In that case, you may need to contact a professional wildlife removal service for humane eviction and relocation, following your local laws.

Companion Planting and Less Tasty Alternatives

While no plant is completely groundhog-proof, they have strong dislikes. Interplanting your cabbage with these can offer a degree of protection:

Strong-scented herbs: Rosemary, thyme, and oregano.
Flowers: Marigolds, snapdragons, and geraniums.

You can also try planting a sacrificial crop of clover or alfalfa away from the garden. Sometimes, offering an easier food source can distract them from your prized vegetables. This strategy dosen’t always work, but it’s worth a try.

A Step-by-Step Action Plan for Your Garden

Confirm the Pest: Look for clean-cut cabbage damage and large burrow holes with fresh dirt.
Secure the Perimeter: Install a 3-foot-tall fence buried 1 foot underground, bent outward.
Remove Cover: Clear away debris and mow grass around the garden to eliminate hiding places.
Use Active Deterrents: Set up a motion-activated sprinkler near the damage.
Apply Repellents: Spray a cayenne pepper mixture on and around your cabbage plants.
Monitor and Be Persistent: Check for new damage daily and refresh repellents weekly. Groundhogs are habitual, so consistency breaks their routine.

Frequently Asked Questions (FAQ)

What vegetables do groundhogs eat the most?

Besides cabbage, groundhogs love beans, peas, carrots, broccoli, and lettuce. They are especially fond of young, tender plants.

Will groundhogs eat cabbage whole?

They often eat the outer leaves and can devour a young head entirely. On larger heads, they’ll take big, ragged bites out of the side, ruining the whole thing for harvest.

What time of day are groundhogs most active?

Groundhogs are primarily diurnal, meaning they forage during the early morning and late afternoon. This is when you’re most likely to see them or when damage often occurs.

Do coffee grounds repel groundhogs?

There is some anecdotal evidence that the smell of used coffee grounds can deter them, but it’s not a strong or reliable method on its own. It’s best used in combination with other tactics like fencing.

How can I tell if a groundhog burrow is active?

Look for a clean entrance with no cobwebs, fresh dirt around the hole, and well-worn paths leading to and from it. The presence of flies can also indicate an active den.

Protecting your cabbage from groundhogs takes a mix of good fencing, smart gardening habits, and consistent deterrence. By understanding their behavior and implementing these steps, you can greatly reduce the chances of loosing your harvest. Remember, the goal is to make your garden less appealing and accessible than the other options they have around. With patience and the right barriers, you can enjoy your homegrown cabbage all season long.
