Gophers might be cute, but they can quickly ruin your garden and landscaping. They tunnel under the surface of the ground and feed on the roots of plants, which quickly kills the plants. Before you know it, you have a half-dead lawn riddled with gopher holes! Gophers are tough to get rid of, so if your land is still gopher-free, there are a few steps you'll want to take to keep it that way.
Plant some lavender, shasta daisies, and foxglove.
Gophers do not like any of these plants. If they encounter their roots, they tend to turn away and stop bothering the area. So, consider planting a border of one or more of these plants around your garden beds or even around your whole yard. Shasta daiseys are very hardy and don't require a lot of water, so they are a good choice if you are short on time. Foxglove grows pretty tall--so it makes a great border plant--and lavender has a lovely scent. (Although gophers do not agree.)
Install fencing around valuable plants.
If you have any valuable or very expensive plants, you may want to individually protect them from gophers by surrounding them in below-ground fencing. Made from wire mesh, you can install this fencing by digging a trench around the plant, and then pushing the mesh fence down into the trench. Make sure it extends three feet or so below ground since the gophers will dig to this depth. Leave a few inches of fencing above ground so you know where the fence is.
Spray your yard with gopher repellents.
This step is really only necessary if you know there are gophers in the area--for instance, if you have seen them on your neighbor's land. You can purchase gopher repellent sprays at most home improvement stores. Spray one along the outside barrier of your yard, and repeat this step about once a week. If it rains, spray the perimeter of your yard again as soon as the moisture dries up.
Most gopher repellents come in a powder or granular form that you must then dissolve in water. They may have an unpleasant odor that lingers for a few hours after spraying, so make sure you don't spray before a barbecue party or other special event.
With the tips above, you can keep gophers away. If you see them on your land anyways, contact a pest removal company.
