Gold Standard Hosta Leaves Have Holes And Turn Yellow In Mid July

Question From: p. lebryk - Saint Clair Shores, Michigan, United States
Q: My gold standard hostas, handed down from my grandfather's garden looks great at the beginning of the season. By mid July some leaves turn yellow. There are holes in the leaves. I cannot find any slugs in the soil. There are a lot of ants. What can I do to avoid the problem this year. They are huge and beautiful right now. They develop lavender flowers in late summer. Thanks. I read your column faithfully. Paula, Saint Clair Shores, Mi.

A: Slugs appear at night and do their dirty work so you rarely see them. Use Sluggo according to package directions to get rid of them. Can't give you a reason for the yellow leaves. You can cut them away to tidy up. Best And Happy Yardening, Nancy.
