Thinking about the yard is not something a lot of people will be doing at this time of year. But the lawn and garden industry is. A study by the state Small Business Research and Information Center in Rolla says many two-income families are too busy to do the things to their yards they’d like to do, so they’re hiring more and more professionals to do it for them. The Center’s editor, Cathy Frank, says that’s putting pressure on lawn and garden companies to find and keep good workers. She says the growing understanding that a good yard can increase property values is leading more people to hire professionals to create and take care of good yards.
