weed killer and overseeding
Hi, I am new to gardening and wanted to get some advise. In summers my lawn is typically covered in clovers and crab grass. It is also very dry and patchy. I purchased Hi-Yield Weed and Grass Stopper with Dimension Herbicide and was wondering when exactly I should apply that? I thought maybe mid-late march? I was also wondering how long after I apply the herbicide I should aerate and overseed? After I apply seeds when do I fertilize? I wish there was a step by step tutorial on how to do this! Thanks!!
You've come to the right place! Take a look at our Turfgrass Maintenance Calendar for Maryland Lawns. There is specific information on what to do when for good lawn care. http://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/lawn_pubs/HG112...
Having some weeds in a lawn is acceptable and you should be aware of the risks of lawn herbicide use. http://extension.umd.edu/hgic/topics/lawn-herbicides
Proper fertilizing, mowing, and overseeding will produce a healthier, thicker lawn, less susceptible to weed infestations. Research shows that mowing tall fescue at 3-4 inches and seeding bare spots will reduce crabgrass infestations.

Aeration is best done in the fall when the lawn is actively growing. For a complete guide to lawn management, read Lawn Establishment, Renovation, and Overseeding. https://extension.umd.edu/sites/extension.umd.edu/files/_docs/programs/hgic/HGIC_Pubs/lawn_pubs/HG10...
