Ok - here is a question - what do you do when the spots are ALREADY there? By giving him the apple cider vinegar now it wont take them away will it?
How do I fix my lawn?
We are lucky - he goes only in one corner of the grass, but still - almost that whole corner is yellow grass now.
Sometimes his new thing is to go on the pavement - just as of like 1 month ago - especially if it's raining and the patio is wet - not sure what that is about....
Anyway - how do you FIX the hot spots?
You'll have to water that area A LOT to dilute the acidic content. The grass *may* grow back on it's own if you do that, if you water 3-4 times a day for 20 minutes or so in that area and are not getting grass coming back in 2-3 weeks you'll have to put down new seed right there and water it until it starts to grow.
