Lawn Care

So now that the weather has turned to these wonderfully humid days here in south Texas I start looking in my backyard at my lawn.  I know I have mentioned before that we have two medium to large dogs and one of them is running the fence line barking at something on the other side every morning right around the time I put my daughter down for a nap, like CLOCKWORK!  Needless to say the grass back there is non existent so we look to the rest of the lawn which has somehow turned into a big weed patch, dandelions, clovers, etc.  You name it, we have it.  I found a "recipe" online that is supposed to kill grubs and bugs, turn my lawn a rich green color and provide the nutrients that I guess this soil is lacking.  Soil?  Who has soil?  We live on rock.  So where does the water go when it rains? Nowhere....it sits in large swampy areas in my back yard for days, attracting those lovely mosquito's and you know what they say, everything is bigger in Texas.  Well I have yet to mix this concoction and spray it down on my lawn, I mean it can't hurt can it?  It involves mouthwash, ammonia, beer (woo hoo!), dish washing soap and soda or pop as they call it here.  I can't wait to see what happens, worse comes to worse I'll have a clean, minty fresh lawn with a buzz.
