Deer are animals that can cause a great deal of damage to your garden and landscaping if you leave them unattended. You might think that deer don't care about plants, but they actually hate the smell of plants.
Deer hate the smell of mint, so all you need to do is put some mint leaves into a pot with water and leave it by your door or windowsills, and they'll run away from that smell. You can also plant mint around other plants or in between rows of flowers - deer hate that too! Some deer repellents can be used as well as traps to keep deer away from your garden without harming them. It's important to remember not to put out food for deer or feed wild animals in order to avoid attracting unwanted guests into your home.
