Most of these columns are on current priorities in my own garden. The premise of course is that many gardeners could be dealing with the same issues at any given time.
Recently, when we listened to those people who always seem to know what’s going at, we learned that 2012 is a big year for gophers.
In the past, I have relied on two visiting cats to keep my garden gopher-free. (I don’t know where else they get their food, so they probably are feral felines.) The result of their advancing age plus a peak in the local gopher birth rate is a record number of gopher mounds.
It might be possible to avoid gopher problems entirely by limiting the garden to plants that gophers do not enjoy. This approach limits the gardening experience severely and still might not succeed: hungry gophers don’t always follow the rules.
The first step toward “control” (the polite term) is to confirm that you have gophers, rather than relatively harmless moles. Gophers are herbivores; moles are omnivores, but mostly eat earthworms and insects. Gopher mounds are crescent or horseshoe shaped when viewed from above. The hole, off to one side of the mound, usually is plugged. Mole mounds are more circular and volcano-shaped when viewed from the side.
One gopher can create and abandon several mounds in day, so the gardener’s challenge is to find the gopher’s main burrow, which will be six-to-twelve inches deep and connected to a mound. When you see a fresh-looking mound, poke around with a stick or metal probe until you feel a drop of about two inches, indicating that the probe has entered the burrow. This might be the main burrow, where you should set your traps.
Use a shovel to expose the burrow enough to set your traps. The popular Cinch Trap, available at most garden centers, comes in small, medium and large sizes. Use the size that fits snugly in the burrow you found. Set two traps according to instructions (watch your fingers!) and place them in opposite directions in the burrow, to trap the gopher coming from either direction.
Baiting the traps is optional. Fruits, vegetables or peanut butter are good choices. You could also use toxic baits, but that is personal choice and probably not ecologically wise.
Connect the traps to stakes with baling wire or light chain, for easy removal. Cover the excavation with dirt clods, wood, cardboard or anything else to exclude light.
Check the traps regularly and reset them as needed. If you haven’t caught a gopher in three days, try a different location.
Benjamin Franklin probably wasn’t thinking about garden pests when he said, “Energy and persistence conquer all things,” but that’s good advice for gopher hunters.
