I saw 4 raccoons in my vegetable garden, doing what they do best with people's gardens. Please let me know if I could plant anything in or around at the borders to my vegetable garden that would work as a racoon repellent. I don't want to use chemicals.
Get a wire fence around your garden. There's 'field fencing' with smaller openings at the bottom that get a bit larger towards the top. Once these little brainiacs have found what they want, you have to get fencing. I have a problem with them as well as bunnies. Well, not any more. My greenhouse and outdoor garden all have this 'bunny fence' installed. Have to dig a 6" trench so they can't dig underneath. You might have to find a mesh to pull over the top as well. Bunnies don't hop over but raccoon (sp) are far more intelligent!! I adore raccoon!! Bunnies, too...well, all animals. Trick is to live in harmony. Killing anything NEVER SOLVES A PROBLEM. Never. Tide rolls out, tide rolls in. Lots more to take their place. Poison...interestingly...actually causes animals such as rodents, raccoon, squirrels, bunnies...to have larger litters. This fence is inexpensive, easy to install and you'll be able to sleep at night!! You could also FEED your raccoon somewhere distant from your garden...stuff like your vegetable scraps. I know others are flipping out with this but I feed bunnies, raccoon, raven and deer with stuff that would normally go into my compost and I live in total harmony. I also have dogs (I would never allow to chase and kill) but the fact their smell and presence is obvious, makes a huge difference.
There is actually an all natural alternative that I have found to be extremely helpful. There are no harmful chemicals used, however a putrid odor will accompany the use for a day or two. The product is called Repels-All.
I only do organic (natural) gardening for my family and this stuff has saved my strawberries, blueberries and tomatoes. Again, the stench is enough to drive some humans away but lessens after a few days. I prefer liquid applications, but the granules can be easily dissolved in a water solution.
