    Our lawn is now having brown patches all over the place. We’ve never had this before. The grass is dying , We are concerned because it seems to be spreading. Any idea of what it could be? Thank you

      What kind of grass is it? Are you watering? If so, how often? Have you used any fertilizer or pesticides on the lawn? If so, when and what?

    This is my first year to grow Canna’s. I’ve read that I need to dig them up for the winter but I’ve also read that depending on USDA Zones that I may be able to cover with a heavy layer of mulch. Given our location does anyone have any experience or thoughts with one method or the other?
