Will Squirrels Eat My Garden: What to Plant to Deter Them (And What They Love Most)

Squirrels are opportunistic feeders with a particular fondness for high-energy foods like fresh vegetables, seeds, and fruits. 🌱 Their natural diet includes nuts, berries, and tender greens—making your garden an all-you-can-eat buffet.

The problem worsens in early spring when they’re rebuilding fat reserves after winter, or during droughts when natural food sources dwindle. Even a single squirrel can strip a raised bed in hours, leaving behind chewed leaves and half-eaten plants.

To protect your hard work, focus on scent-based deterrents like marigolds or daffodils, which squirrels avoid due to their strong aromas. Physical barriers, such as chicken wire or mesh netting, also work well for vulnerable crops.

I’ve found that planting rosemary or garlic near high-value plants creates a natural repellent zone—squirrels dislike the pungent smells. The key is combining multiple strategies, since no single method is foolproof.

Why squirrels love your garden vegetables

Squirrels are hardwired to seek out high-energy foods, and your garden is basically their version of a fast-food drive-thru.

Their natural diet in the wild includes 40-60% plant matter, with a focus on foods rich in fats and carbohydrates to fuel their high-energy lifestyles. 🌰 For example, a single acorn contains about 15-20% fat—the equivalent of a squirrel’s protein shake.

When they encounter garden vegetables like corn (which has 70% carbohydrates) or beans (packed with 20-30% protein), it’s like finding a gourmet meal after a long fast.

The timing of their foraging is also critical. Squirrels enter a hyperphagic state in late winter and early spring, where they consume 2-3 times their usual food intake to build fat reserves for breeding season.

This is why your spring lettuce or peas become a prime target—they’re soft, nutrient-dense, and easy to digest. Even young seedlings trigger their foraging instincts because tender shoots mimic the high-water-content foods they’d find in nature, like fresh berries or new leaf growth.

Garden layout plays a surprising role too. Squirrels prefer open, accessible spaces where they can spot predators from a distance while foraging.

A raised bed with 6-12 inches of soil depth is especially inviting because it mimics their natural digging behavior—think of how they bury nuts in loose soil. 🌱 Conversely, enclosed beds or containers with tight-fitting lids reduce their access.

The key is removing easy entry points, like low-hanging branches or gaps in fencing, which can turn your garden into a squirrel buffet overnight.

Here’s the science behind their crop preferences: squirrels have a keystone species diet, meaning they prioritize foods that provide the most calories per bite. A single ear of corn yields 100-150 calories—about 10% of a squirrel’s daily energy needs—while a handful of beans delivers 50-70 calories.

Compare that to their natural diet of nuts, which average 150-200 calories per ounce, and you’ll see why garden veggies are a close second. Their teeth are also adapted for crushing hard seeds, but they’ll happily gnaw through softer garden plants when the opportunity arises.

Seasonal hunger spikes make the problem worse.

During droughts or late winters, squirrels will raid gardens up to 50% more aggressively because natural food sources like mushrooms or fallen nuts are scarce. 🌿 Even mature plants aren’t safe—squirrels will strip leaves from tomatoes or melons to access the juicy interior, leaving behind a mess of chewed foliage.

The irony? Many gardeners plant these crops specifically for their high yield, only to watch squirrels turn them into a free-for-all feast.

What most gardeners don’t realize is that squirrels also target hidden garden treasures, like the 20-30% of seeds buried in compost piles or the tender roots of carrots and beets.

Their digging can uproot entire plants, and their chewing leaves behind jagged edges that make produce inedible. The damage isn’t just cosmetic—it’s a direct hit to your harvest.

Best plants to deter squirrels naturally

Start by planting marigolds—their strong scent confuses squirrels and masks the aroma of nearby vegetables. I recommend placing them in clusters of 3-5 plants every 2 feet around your garden's perimeter. Daffodils are another excellent choice, as squirrels avoid their toxic bulbs.

Plant them in early spring for maximum effectiveness, especially near tulip or crocus beds, which squirrels also target.

For a multi-layered defense, incorporate alliums like chives, garlic, or onions.

These plants release sulfurous compounds that repel squirrels while also improving soil health. 💛 Place them strategically between rows of vulnerable crops like lettuce or peas. Rosemary and thyme work well too—their woody stems deter squirrels from climbing, and their pine-like fragrance creates a natural barrier.

Consider adding physical barriers like chicken wire (1/2-inch mesh) around raised beds or netting over fruit trees. For delicate plants, try plastic tree guards wrapped in aluminum foil—the reflective surface startles squirrels.

I’ve had great success with 12-inch tall wire fencing buried 6 inches deep around garden edges, which blocks both climbing and digging.

Don’t forget about ground covers like lavender or mint, which spread quickly and create dense mats that squirrels avoid. Their strong aromas also help mask the scent of your prized vegetables.

For container gardens, try basil or lemongrass—their citrusy notes repel squirrels while adding culinary value to your harvest.

Pro tip: Rotate your repellent plants annually to prevent squirrels from adapting. For example, if you used marigolds last season, try snake plants (Sansevieria) this year—their sharp, bitter leaves deter foraging.

Combine these strategies with regular garden maintenance, like removing fallen nuts or seeds, to make your space less appealing.
