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.
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.
