digging up crabgrass
the front lawn in my new place is almost all crabgrass. Wanted to check with you to verify that my plan for getting rid of it will work. 1. spray with roundup 2. rent a turf cutter and dig up/out the "lawn" 3. water and spray anything that sprouts all spring and summer or should i tent with plastic and fry the new growth? 4. plant new lawn in the fall I'm not sure the sod cutter will go deep enough to get all the crabgrass runners i'm 76 so digging by hand is not possible.

Thank you for your question. Having used the sodcutter approach, I can attest that it is no ‘silver bullet,’ but may be a start. Grasses are rhizomatous, and often extend below the cutter. Here is a comprehensive article about its control that may provide some ideas: http://ipm.ucanr.edu/PMG/PESTNOTES/pn7456.html Once you’ve gotten it up (and covered, as you suggest) and treated, here is an Extension article about starting over: https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/ec1550.pdf Good luck!
