Annie asked: My garden shares the backyard with my dog. Do you have any ideas on how to keep the dog from damaging the new plants without having to build any extraneous fencing for sending her back to the pound?
Annie's question is really good! This is especially a problem if you have a large dog that likes to dig! In a matter of 10 minutes most of a good garden can be distroyed by a dog looking for the bone that he buried last fall in all that soft garden soil.
Of course the most permanent solution IS a fence. However, when another fence is not an option there are other things that can be done. These require effort and some extra garden maintence, but if done consistantly, are effective.
1. Most pet supply stores carry spray-on products that can be used to protect certain areas of your yard from wandering animals. You won't want to spray your plants with it of course because the chemicals may harm the plant or cause it's fruit to be inedible. So, carefully spray the perimeter of the entire garden area, while standing in the garden and spraying outwardly away from the plants. Make sure and really saturate the ground. This method is really good and the effects will last a couple of weeks depending on humidity and the amount of rain that you get. (Be sure to follow the spray bottles directions.)
2. If number one is too expensive, or more expensive than what you had in mind spending every couple of week, or if you live in an area where the nearest pet supply store is several hours away then this is a good alternative. In a regular spray bottle combine some ammonia, or chlorox, and water. ***NOTE***DO NOT COMBINE AMMONIA AND CHLOROX! the result is a poisonous gas that will make you very sick or cause death if you inhale the fumes.*** So, pick one OR the other and mix it about 1/3 parts chemical into to 2/3 parts water. Apply the same as you would for recommendation #1. Re-apply about every two weeks depending on humidity and weather.
3. This method is also effective and will benefit your plants and garden. Using chemical fertilizers and chemical bug and weed killers usually have a really good effect on keeping away dogs and cats as well. Be sure to apply them as directed on the specific packaging. We use a ground kill in our natural desert landscaping. The ground kill ensures that weeds do not come up in our rocks. Normally cats would love to use our yard for a litter box, but the ground kill keeps them away and we have not had one problem.
4. This is the method that I use every year. I will plant large tomato plants and corn on the perimeter of the garden. Tomato plants have a pungent repulsive smell--which is what the chemical sprays accomplish; a smell that animals don't like--and the corn, once it is a few weeks along make it difficult for dogs to find their way into the garden. Also placing some noise makers like bells, chimes, etc. will aid in keeping pets out of the garden area. I grow an organic garden and so I don't use any chemical fertilizers, bug spray, or weed killers. Occasionally I will combine this method with step number one if wandering cats decide to start using my nice soft garden soil for a bathroom. This method may not work for everyone in every situation, but it keeps my 100 lb rottweiler who is VERY fond of digging out of the garden. She HATES the tomato plants and won't even try to get past them if I want her to.
While your garden is small and the plants are young , if you have planted according to #4, I would start with #1 then once the plants mature you shouldn't have to apply the spray again.
PS: Make sure that your dog knows the garden area is off limits. When you are out planting, weeding, watering, and caring for your garden do not invite him to join you in or near the garden. Inviting him to be near you gives him the idea that it's OK for him to be in the garden with or without you. Dogs are smart and if they know the garden is off limits it makes the other methods even more effective!
