Free lawn-care workshop

Want a better-looking lawn this summer? Now is the time to tackle crabgrass and dandelion prevention. Gertens is offering a free lawn-care workshop on several upcoming Saturdays. The workshop will cover seeding, fertilizing, and general maintenance for spring lawns, with plenty of time for your questions. The workshop will be held at 10 a.m. on April 25, May 2, 9, 16 and 23.

Also at Gertens on April 25 will be a free workshop on installing eco-friendly permeable pavers.
