Question
Mike,
I have a strange problem. My zucchini plants are being attacked. This past weekend I noted that one looked dehydrated. When I inspected I found that the plant was cut at the base and the root system was missing. Today I went out and replaced it only to find that a second was destroyed in the same manner. Any ideas? My great fear is that once all the zucchinis are gone then the "attacker" will go after my other plants.

Benson, it sounds like you suspect an animal is invading your garden. If the root system is being lifted up from the ground, I tend to agree with you.

It is always difficult to guess what type of animal is eating a particular plant.  The only way to know for sure is to actually see it. Likely culprits include deer, raccoons, rabbits, gophers, and groundhogs. If the plants are mature, I would rule out rabbits.

You have four options at this point.  You can fence your garden in, attempt to trap the animal, use an animal repellent, or 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 an option, 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 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.  Marigolds, due to their undesirable scent and taste, are another option.  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 and marigolds next spring to deter the animals next year.  In the meantime, I would try the trapping to see how many animals are actually visiting each night. You may be pleasantly surprised to find that only a few are causing your problems.

I hope this information helps. Please write again if I can ever provide assistance.

Mike
