Top 5 ways to keep mice out of potted plants
Deterring mice from your yard naturally is the best way to keep them out of potted plants. Avoid using poisons or traps if you can by using natural deterrents like strong smelling plants, insect wires over pot drainage holes and place peppermint or eucalyptus oil on the rim of plant pots
1. Strong smelling plants in your garden
Strong smelling plants like lavender, rosemary, peppermint or mint are fantastic for deterring mice from your garden. Mice have sensitive noses so will keep away from strong smelling areas. These strong smells can stop them from smelling and detecting predators so they will clear out to where the air is clear.
2. Insect wire over drainage holes
Glue insect wire or fine mesh over the drainage holes of pot plants. This will prevent the mice from digging into the pot plants from ground level making it harder for them to come in and make their home.
3. Peppermint oil
Peppermint oil can be dropped onto the rim of plant pots. This works very well for indoor plants but will need to be reapplied regularly on outdoor plants when it rains. This strong smelling oil is natural and will deter mice.
4. Eucalyptus oil
Eucalyptus oil placed on the outside of plant pots will work to deter mice and smell great. This natural oil smells great but mice hate it. Place it on the rim and outside of your plant pots.
5. Hide their food
Mice will find a home in your pot plants if they have a good food source. Pet foods like dog biscuits, cat food and chicken pellets are favorite foods of mice so clean up any excess to stop their supply. Mice also love to raid worm farms and compost bins so make sure you have tight fitting lids to deter mice from your garden and plants.
6. Garlic and onion
Garlic and onion smell strong and mice hate them. Garlic chives or society garlic are also a great option to plant around your garden to deter mice. Society garlic is one of my favorites as it has bright purple flowers that look great in your yard which can also be used in cooking.
Why mice like potted plants
Potted plants can become the perfect place for mice to make a home as potted plants particularly can warm up in the sun and be a cozy home. Mice can find their way in through drainage holes and will dig out a small burrow to rest in. This keeps them and sometimes their babies warm, especially in the cooler months.
Potted plants can be a great food source for mice who can snack on organic matter in the soil, plant roots or fertilizer. Mice can snack on your plant leaves and stems providing them with a nutritious snack and some high fiber meals.
Potted plants provide mice with the perfect protection they need from cold weather, frosts, snow and rain. The organic matter in potted plants can keep the mice warm and the top soil will protect them from the cold weather.
Potted plants and the soil in the pot provides the perfect location and material for mice nests. Mice can dig out a small amount of soil, bring in nesting materials and create a nest for their babies. Mice are rapid breeders and I a few weeks they can build a next and birth 6-8 mice babies (or kittens).
Mice can damage potted plants
Mice can damage potted plants as they bury into the soil, remove dirt from around plant roots and chew and damage small feeder roots. If dirt is removed from around plant roots the roots can dry out and be starved of nutrients.
Mice can eventually kill potted plants so preventing them from getting in is an important step to protect and save your plants.
