The Buck Stops Here
Sure, they're pretty to look at, if you're quick—and quiet enough to catch a glimpse of deer galloping off into the distance. But set loose in your garden, they will ravage your tender tulips and plump pansies, leaving foliage raggedy and the fruits of your labor plumaged. Fortunately, with a little bit of insight into their habits, you can prevent your flowers, bulbs, and vegetables from becoming a free buffet. Use these 20 tips, ranging from home remedies and recipes to organic solutions and humane exclusion techniques, as part of a prevention plan you should put into effect now—even before you've spotted the season's first deer.
1. Don't over-stock your garden with tasty plants
Springtime finds deer at one of their hungriest states: Does are nursing their fawns, and anxious to gain back weight lost during the winter's freeze, every deer is looking to gorge on high-protein, moisture-rich plants. Think twice about growing large amounts of English ivy, lettuces, beans, peas, hostas, impatients, and pansies. Fruit trees are prime targets too. "The sweetness and flavor of strawberries and peaches make them as attractive to deer as they are to people."
2. Keep deer-favorite plants close to the house
That way, you can keep tabs on the plant's progress at all times, making sure it doesn't become a meal. As a general rule, deer love to dine on anything that's smooth, tender, and flavorful, including chrysanthemum, clematis, roses, azalea bushes, and various berries.
3. Plant pungent perennials as a natural barrier
With wildlife biologists' modest estimate of 18 to 24 deer per square mile, and full-grown adults each feeding on 6 to 10 pounds of greenery a day, the best line of defense lies in making your backyard less appetizing than your neighbors. Deer rely heavily on their sense of smell for feeding, so adding patches of strongly scented herbs—from garlic and chives, to mint and lavender (left)—can mask the appealing aroma of nearby annuals.
4. Plant thorny, hairy, or prickly foliage
When a deer is deciding what to have for dinner, the sense of smell trumps touch. But that doesn't mean deer aren't bothered by certain textures mid-meal. Try incorporating fuzzy lamb's ear, barberries, and cleome near the plants you want to protect—and where deer might find entrance into your garden in the first place.
5. Make deer-resistant substitutions
Massingham Hart suggests trading tulips for daffodils, which tend to top the deer-resistant plant lists. Pick roses that are particularly thorny, including Scotch or rugosa roses. And if you're looking for flowers that'll add a certain color or provide a certain function in your outdoor space, consult the list of deer resistant plants from Rutgers University to see what swaps you can make in your garden.
6. Don't underestimate the power of scare tactics
As neophobes, deer fear new, unfamiliar objects. Though they aren't always attractive, scarecrows, sundials, and other garden ornaments—especially those with movable parts—make deer skittish. Use them in combination with wind chimes or bright lights for added effect.
7. Rotating repellents throughout the growing season
The University of Illinois Extension School recommends Havahart's Deer Away Big Game Repellent, a powder that contains a high concentration of smelly egg solids to target sense of smell. Also on the market: Deer Off, a spray product containing capsaicin that deters predominantly by taste, and Hinder a spray of ammonium salts of higher fatty acids creates an odor barrier. Reapply repellent after rainfall, and use a different formula from time to time to protect plants and prevent deer adaptation. Coverage should start from the ground and extend upward six feet.
