Squirrels digging in flower pots
Thanks for writing. This is a very common problem in spring and one that's there's not really a good answer for. You can try sprinkling hot pepper flakes on the soil surface of your plants; its hot oils irritate squirrels just like they do people. Or, there are squirrel repellents (such as Squirrel Stopper) on the market under a variety of brand names; some people find success with them.
Other than that, I've never found or heard of anything that works reliably except patience; the squirrels generally lose interest in your pots after a couple of weeks.
