I have a cottage in northern Michigan and need some advice on what type of seed to use. Because I am unable to water frequently throughout the summer months, half of my new lawn has died. The area would be 70% sunny and 30% shady so I need a type of grass that would be drought tolerant because I am not there the entire summer to water. I have searched on a well-known grass seed company's website and found a couple varieties that might be suitable. One was for sunny conditions....or sun & shade conditions, tall fescue, etc. Each one has their own characteristic so I am unsure as to what variety to use. I certainly would appreciate any advice from you all. And please let me know if you need more info. Thanks.
