Can you recommend how to grow potatoes in barrels due to a wire worm infestation?
I have decided to grow potatoes in half whiskey barrels because my garden soil has wire worms in it and is not good for growing potatoes. If I plant them in the barrels, what kind of soil should I use? What should I fertilize them with? Compost? If there is a way to get rid of wire worms organically?

As for wireworm, we typically recommend cultural controls such as controlling weeds in the area where wireworm is present and potentially not growing crops in the infested area for a year or two. Here is more information about wireworm: https://hort.extension.wisc.edu/articles/wireworms/
