How can I repair patchy grass?

Best method for a lush lawn is to keep it healthy. Since you are using well water, I would have it tested for nutrients. Typically in the fall it is a good idea to dethatch the lawn and overseed with a winter variety type grass. Let me find you some sites.

Here are some great sites for you.

Hi Noeline,

I have had the best luck speaking with local green house workers. I am in North America and it is currently summer here. This tells me you and I are on opposite sides of the globe if its winter where you are. I would check with someone local to get the most accurate information for growing and maintaining grass.
