Holes in hosta leaves?


Why do the leaves on my hostas look like swiss cheese, with so many holes? What is eating them & what can I do about it? - Nancy -

    If you are not seeing any pests during the day, the holes in the hosta leaves are most likely from slugs, which feed at night. Look on the underside of the leaves after dark. Another telltale sign would be the shiny trails left from the slug slime.

    Here is the KSU bulletin on slugs: http://www.hfrr.ksu.edu/doc1704.ashx

    Hope this helps.
