We have a customer with a fast food restaurant in a mall parking lot. One thing you can count on in a mall parking lot is that when it snows there will be plenty of salt put down. What happens to the lawn?
We tilled in gypsum to correct the high soil salinity, added some top soil, and spread a blend of mostly rye but also some fescue and bluegrass and two weeks later:
We will encourage the owner to do a normal aeration and seeding at the end of the year, and monitor these new areas throughout the season because predominantly rye lawns are susceptible to certain diseases and are less heat tolerant than fescue/bluegrass mixes. But its quick coverage is hard to beat!
