We Like Our Potatoes Mashed, Roasted, and Pest-Free
Anyone who grows potatoes loves them, so why not celebrate them? National Potato Day falls every year on August 19th; that’s right, there’s a day devoted to our tuberous friends. Some of us like ‘em mashed, others prefer roasted, but we all want them to be pest-free in the garden. So be on the lookout for some of these common critters that love potato crops.
The Pest Bible
Before we get started, if you don’t have it already, I recommend the book, The Vegetable Garden Pest Handbook: Identify and Solve Common Pest Problems on Edible Plants by Susan Mulvihill. No gardener should be without this resource; beyond potato problems, you’ll learn about every pest in the universe, the food crops they go after, and how to handle them.
Potato Pests
Growing potatoes is super rewarding because the yields are usually very high and are always delicious! They do well in the ground or in buckets, and there are so many varieties out there to please every palette.
But if you don’t regularly observe them in the garden, you risk losing them to pests or diseases.

You might have a beet armyworm problem

You might have a blister beetle problem
If you see wilting plants and irregular holes in the leaves and flowers
