How to repel rabbits and deer from eating hostas and flowers

Deer and rabbits shy away from odors not found in their normal habitat and, because of their sensitive noses, especially dislike strong scents of peppermint, cinnamon, cloves, citrus peels, vinegar, etc. I found the first three in a product called Scent-inals, as essential oils, six small bottles with wicks, advertised to last for three months. If you opt for vinegar, put it in small containers so that it does not touch your plants as it may harm them. Crushed garlic works quite well, but for next to the house, dried blood, available at garden centers, is an old remedy and the scent is not obvious to humans.

Below are a couple of paragraphs I found somewhere on the Web. Sorry I don't have the source to give them credit.

Which plants should I grow to repel rabbits and deer?

Planting garlic, onions, chives, lavender, rosemary, and sage around rabbit-susceptible plants will repel rabbits. Deer repellent plants include: lavender, onion, catnip, sage, chives, garlic, spearmint, and thyme. Be sure to strategically place these repellent plants around and in between rabbit and deer-susceptible plants. Also, place some along the property line and especially at key points the rabbits and deer are using as entryways, which can even deter them from coming onto your property.

I read about using a cuisinart

to grind up bars of Irish Spring soap. Deer do not like that scent, so spread it around bushes and trees they like to chew on.

Thx, I'll try it. Place on the foliage? or where?

I just remembered, rabbits don't like marigolds.

Grind up some Irish spring soap and spread it around. They hate the smell!
