My lawn is being taken over by violets. I think it is because the lawn is cut too high. My person who cuts the grass says no. The grass will force out the weeds but violets keep spreading. Help. I could use round-up but that kills the grass. What can I do?

Actually, mowing a lawn too short encourages wild violets. Mowing short is a very common problem.
Here is our webpage on wild violets: http://extension.umd.edu/hgic/wild-violet
Notice in particular 'Conditions that Favor Growth'. If you don't change the conditions you have now, the violets will just return.
To combat wild violets, thicken your lawn. Fall is prime time to plant grass seed.
For overseeding help, this is a great little source: http://extension.umd.edu/sites/extension.umd.edu/files/_images/programs/hgic/Publications/HG102%20La...:
