Squirrels may be cute in trees or running around the neighborhood, but they can pose a serious threat to plants in flower pots. As many people know--if only from cartoons--squirrels save food for later by hiding it. Sometimes they choose a flower pot as their hiding place. Even if squirrels do not hide anything there, they may still destroy your plants by digging numerous holes in search of a lost nut. There are a few tricks you can try to keep your flower pots safe.
Remove the top 1 inch of soil from a flower pot you have planted bulbs in, and measure the circumference of your pot at the top of the remaining soil.
Cut a piece of hardware cloth or chicken wire to that measurement, using metal shears or side cutters. If using hardware cloth with bulbs, cut a small hole in the cloth above each bulb to ensure that the stalk can grow through it.
Put mothballs on top of the soil. Squirrels do not like the odor and will not be able to dig the mothballs up when the mesh is on them.
Place the mesh piece on top of the soil and mothballs, and replace the soil you had taken out.
Secure the mesh by placing heavy rocks around the inside edge of your flower pots. These will help hold it down when squirrels try to dig.
