Question
Mike....Help...I was told that marigolds attract good bugs that eat bad bugs, so I planted about 25 in my vegetable garden. Every few nights something bites off the flowers, never more than one per night, and then leaves the petals there. We do have a skunk in the neighborhood. Any thoughts?

Answer
John, it could be one of several pests including rabbits, possums, or gophers.  Without you identifying the animal, it is very difficult to determine which of the three is your culprit.  But based on my own experience, I would bet on a rabbit.

Regardless of which animal it is, you have four options at this point.  You can fence your garden in, attempt to trap the animal, use an animal repellent, or as a last resort use poison to eradicate it.

Fencing is probably the most effective option, but it also is the most expensive and impractical depending on the size of your garden.  It also can be unsightly.  If you do choose to use fencing, make sure it is at least 2' high and 6” deep.  Deer require more costly structures since they can leap over anything smaller than 8 feet.

Trapping is relatively easy.  I recommend purchasing a commercial trap sized for the animals suspected above.  Havahart makes a very reliable one which can be purchased at most garden centers. Bait the trap with carrots, lettuce, and peanut butter.  Once caught, you'll need to relocate the animal to a location at least one mile away.  Traps can be highly effective, but it will be a constant effort.

There are many chemical repellents sold in local nurseries such as Ropel.  Although most are effective, they need to be reapplied after a rain. Other organic repellents which have proved effective are cayenne pepper, blood meal, coyote urine (also available at most garden centers), and garlic spray.  Garlic is extremely effective at repelling animals and insects.  Many gardeners plant it liberally throughout their garden for this very reason.  Just be sure to never plant it near beans or peas as it tend to stunt their growth.  Fully grown marigolds, as opposed to the tender leaves of a young seedling, are another option due to their undesirable scent and taste.  They are especially effective against rabbits.

Finally, and the least desirable alternative, is  poisoning.  Most garden centers carry various poisons which can be used.  Keep in mind, however, that they are also toxic to pets and humans, and should never be placed directly in the garden.

In summary, repellents are probably the most practical alternative you have at this point.  This fall, I would plant plenty of garlic to deter the animals next spring.  In the meantime, I would try the trapping to see how many animals are actually visiting each night. You may be surprised to find that only a few are causing your problems.

I hope this helps.  Good luck, and please write again if I can ever be of assistance.

Regards,

Mike
