Yard taken over by crabgrass
My yard, which is only about 2 years old, is almost entirely crabgrass now. I’ve aerated in fall and planted grass. I’ve put weed killer down in spring etc. Lawn looked beautiful in spring. Then a month ago it all turned into crabgrass. What do I do and when do I do it? Please give me specific steps. Thank you so much. I live this service.
If crabgrass has overtaken over 40-50% of the area, then you will need to do a total renovation of the lawn. If the area is full sun to part shade, seed with a turf type tall fescue grass seed. Here are our recommendations for seed http://www.mdturfcouncil.org/resources/Documents/TT-77%202017.pdf
Please see the following information on lawn renovation,
Also, check the 'additional resources' at the bottom of the page. See the publication Lawn Establishment and Renovation. See page 7 for step by step information. Begin with a soil test. http://extension.umd.edu/hgic/soils/soil-testing
Here is the link to our crabgrass information. Early next spring you need to apply a preemergent to prevent the crabgrass from germinating next summer. A second application may be possible 6-8 weeks later.
