Q.Summer Fungicide Treatment
I planted zoysia sods three months ago, which became a beautiful green lawn this summer. However, I started to notice a few brown patches in some areas. I checked w/some local landscapers. They tell me about ‘fungus’, recommending some products. These products instruct to wait until cooler weather. I live in Florida and cooler weather will arrive in November. Can you give me some advice on a good treatment that can be effective during summer months, or should I let it die.

Be sure to use moss from Canada - it has a different ingredient (it may explain in link above) that makes it better for fungus than U.S. moss.
