Deter Deer with Camouflage Gardening

11/21/2013

52 Comments

 
A deer-proof garden is essentially non-existent, but a highly deer-resistant garden is attainable with a little effort and planning. One key is to practice "camouflage gardening".

Camouflage gardening is the practice of using plants that animals don't like to deter them from eating plants that they do like. Camouflage gardening is mostly focused on deterring deer, but can work for rabbits, squirrels, and even dogs and cats with appropriate plantings. I must point out and stress that this deters animals like deer from eating desirable plants, it doesn't prevent them from eating anything.

Think of it as constructing a castle or defensive military position. The plant you want to protect is in the center of the defensive zone. It's surrounded by a barrier of deer-resistant plants. For superior defense you layer zones with additional rings of protection. You're not building walls to protect plants but using plants to protect plants.

There are certain plants that deer, and similarly many other animals, don't like. Deer tend to avoid plants that are strongly aromatic or bitter tasting, that have a milky or sticky sap, or that have prickly leaves or are tough and hairy. When they encounter these plants they tend to ignore them and move on.

Deer are browsers that amble from plant to plant looking for something they like. If a plant isn't on their list of favorites, they'll keep looking for one that is. This assumes that they have an adequate food selection available. When conditions are bad, as in drought years or when habitat is reduced, they'll eat almost anything to stay alive. In spring pregnant does will eat almost anything.

To get the best protection and to help minimize problems during bad years, the outside protective zone, which is the first that deer encounter, would have a plant that is highly resistant to deer. This layer should have plants that are aromatic with an odor that makes them walk away. You create a scent barrier that prevents them from smelling desirable plants. Lavender, mint, salvia, beebalm, rosemary, and cedar are some plants that have a smell deer avoid and are also rarely eaten.

The second layer of protection would include bad-tasting or toxic plants. The idea is that if they wander past or through the first protective zone they'll come across plants that they don't want to eat. Holly, juniper, feathergrass, zinnia, and barberry are rarely eaten. Plants like elderberry, poppies, bleeding heart, lobelia, and larkspur can be toxic. When deer encounter these plants they should go in the opposite direction.

A third layer of protection is to offer a suicide zone. This is a grouping of fast-growing plants outside the protected area that are less deer resistant. Honeysuckle, trumpet creeper, morning glory, and clematis are plants that deer will nibble without decimating the plant. Flowers that reseed prolifically fit in here too. Planted strategically, these plants can lead deer away from more desirable beds.

With a simple two-stage protection planting plan, deer will come across your landscape, realize they don't like the smells and tastes, and keep on walking. If they're curious or extra hungry, they'll try nibbling on what they find but if they don't like it they'll realize this whole yard isn't worth their time and effort and will move on to your neighbor's yard. They never make it to the roses or tulips or young fruit tree that they would devour.

Adding a suicide zone gives them someplace else to go as they walk away from your garden. They may eat a few clematis or morning glory flowers as they avoid the aromas and tastes of the other zones. Asters, petunias, and small sunflowers give them something else to nibble, and will grow back soon.

As you plan a camouflage garden you don't need to think in terms of clearly defined rings of plants. The first and second protective zones can be intermingled, with aromatic plants planted among bitter and toxic ones. The concept is that one plant deters the deer and when they move to a second plant it deters them too. Ideally every plant they encounter within a defined space is a deterrent and they never move through it.

When you have a mix of plants with many deer deterrent properties it creates a synergy where the entire garden becomes highly effective at deterring deer. A wide spectrum of aromatic plants can confuse deer to the point that they seek a more simple, clearly identifiable source of food... like the big expanse of tulips down the street.

To be most effective camouflage gardening needs to be as year-round as possible. If the plant you're hoping to protect blooms or buds before the others, deer can find it. Your deterrent plants need to be in position and producing their deterring effect.

For example, for early spring your garden border is planted with dwarf juniper, rosemary, sage, or artemisia -- plants that are still fragrant even when they're dormant. A fragrant groundcover like thyme covers the area. A large planting of daffodils, plants deer typically don't eat, brings early color and helps create another deer deterrent barrier. Irises come next, another plant deer typically don't eat. At the center of your display for height and color are your tulips, a plant that deer love to devour. Depending on variety, you may have irises and tulips flowering together which adds extra confusion to the deer. It's not a perfect solution. In a good year your tulips are spared; in a very bad year everything is eaten.

I'm planting my new landscape with entire beds of deterrent plants. One bed has lavender on one side and various spirea on the other. Miscanthus grass provides height and interest. Purple coneflower and yarrow add color. Apache plume fills the center for added texture color and interest. It's highly satisfying to see deer tracks in and around the bed and not a single plant is disturbed.

Another bed has creeping phlox, artemisia, dwarf pines, salvia, yucca, columbines, irises, and daffodils; again, there are tracks but no damage. Next year's new beds will have similar plantings.

We have a resident deer population. They even bed down among the gambel oak trees in our backyard. I'm hoping that they'll get used to encountering so many plants they don't like that by the time I plant young trees and a few other less-resistant perennials they'll have learned to go some place else for breakfast, lunch, and dinner. Already I've noticed more tracks walking around my deer-resistant beds than walking through them.

Get to know your neighbors
For your camouflage garden, research deer deterrent plants. You won't need to sacrifice color, smell, texture, or height. Select plants that you like to grow normally. Then design your beds and landscape with those plants as the first barrier. Continue with plantings of other deer-resistant plants that you want in your landscape. Personalize the space. You don't need to grow plants you don't like.

Camouflage gardening isn't foolproof. The only sure way to protect plants is with a physical barrier. For prized plants and young trees a fence or metal wall is the only sure deer proofing. Used together, camouflage and wire fences can allow plants that deer like to eat to become large enough and established to the point they don't need a fence.

Camouflage gardening works best in a large landscape or garden with enough space to allow planting the necessary barrier plants, but even in small gardens the same principles can be beneficial. Make plants that deer and other animals avoid your first line of defense. Hide your other plants with smells and tastes that deter deer. With a little planning and a lot of luck you may be able to enjoy plants that you've had problems with before.

Ants In My Plants

5/9/2011

Ants become visible in the spring after spending the winter underground and can raise concern among gardeners. In the last week I've been asked by three different gardeners about the sudden explosion of ants in their gardens. Unless you happen to live next to an atomic bomb test range in New Mexico, you shouldn't be too concerned about ants, even big ones.

Most ants are beneficial. They control pests like caterpillars and termites, eat weed seeds, and can improve soil with their tunnels and nests. They clean up plant debris and dead insect bodies. They can help pollinate flowers. They'll move flower seeds, giving them a chance to germinate in a new location. They're an important part of the ecosystem in your garden.

Of course, it's not all good. They can create a colony underneath your favorite plants and produce an unsightly mound. They'll eat plants and roots that are in their way. Some ants will corral aphids and actually protect them as they suck the sap from your plants; the ants feed on the excretion of the aphids, a "honeydew" sweet liquid that ants love. They can invade your home seeking food. Seeing ants in places you don't expect to see them can be a little unnerving, but they're not all bad; California has over 200 species of ants, and only considers less than a dozen as pests.

Dealing with ants is a good opportunity to practice Integrated Pest Management (see my blog,"Integrating Integrated Pest Management"). First determine if the ants really are a problem in your garden. If they're just walking around, checking out the area after waking up, then leaving them alone is easy. If you see a large mass of ants, don't panic, wait and see where they go and what they do; they may just be moving to a new home.

I rarely try to kill or reduce the number of ants in my yard. When I do, it's usually because large numbers have moved into a territory that I've identified for another purpose, like the middle of a vegetable bed. As long as it's not a harmful species like fire ants, disturbing the nest with a shovel may be enough for the little creatures to grab their eggs and move elsewhere. (Important note: if you really have fire ants, they should be reported to your county agriculture agent for identification and control).

If you begin to see actual plant damage due to ants or the aphids they're cowboying, it may be time for action. If they're in a location that is a problem, you probably want them gone. Take some time to determine where their nest is. This may mean following a line of ants, or even a single one, until it leads you to its home.

You may not need to kill a single ant to alleviate your problem. Ants seek out food and then return home by following a scent trail that they made. By disrupting the scent trail you can reduce the likelihood that the ants will return to the food source, like your kitchen. Soapy water will work; sponge off the area that the ant was walking to eliminate the trail. Outside you can spray it with a hose, but plain water is not completely effective, so using a bucket of soapy water is better.

For best control realize that you need to deal with the ants that you can't see. Spraying or dealing with the few on your plants or in your kitchen won't remove the problem. You need to choose a method that attacks them in the nest.

If you feel you need to eliminate the nest, you can use a few methods that are not completely toxic. Diatomaceous earth will act to desiccate the ants and kill them. It's commonly used to control slugs and snails so you just may have some in your garden shed. Sprinkle it around your garden beds and the ant nest.

You can make your own ant poison by mixing boric acid with sugar, honey, or jelly. Place it near the nest to avoid attracting other ants to the area you're trying to clear.

If you decide to use a commercial ant poison you should identify what kind of ants you have. Each region can have dozens of different species and some are easier to remove or kill than others. Ants generally look alike, but upon close examination you'll see that some are brown or black while others are yellow or red. You also want to be sure you don't actually have termites, which are often confused with ants. Do an online or library search to identify the species you're dealing with.  The University of California, Davis has an online key here.

The reason for identification is that different ants react differently to the standard ant poison you can buy. While the poison may kill many of the ants in a garden, it won't kill all types and may actually cause some to move from the original location to other areas, like under or in your house.

Generally, ant baits work better at killing ants in the nest than pesticide sprays. The sprays will only affect the ants that come into direct contact with the pesticide while the baits will be carried into the nest by workers and transferred mouth to mouth and ultimately kill most of the ants.

The initial reaction by many people when they see ants is to want to kill them. I recommend that you stop and analyze their effect on your garden. Chances are they're having a beneficial effect. Don't assume that they're causing a problem. Even if there is a problem, don't rush to kill all of the ants. Ants are an important component in a garden's life force and eliminating them may disrupt the natural circle.

If you choose to take drastic action, practice smart pesticide practice. Deal with the ants directly and don't wantonly distribute harmful chemicals in your garden. 

Be aware that there are ants throughout the world. The attractions that brought ants to your garden are still present and removing a nest just opens up space for different ants to move in. Once you begin trying to control ants, you may start a course of action that takes up a lot of your gardening time.
