Question
What is the best way to raise the ph level of our soil and lawn to counteract the effects of acid dog wee.We have a male dog and he is leaving marks on our lawn . We also live by the sea could the salt content have anything to do with it .

Answer
Hi Julian, agricultural pelletized lime is a cheap and easy way to raise your pH. Apply 40 lbs. per 1000 sq. ft. and your pH will raise about 1/2 point.  This will help your brown spots recover but probably will not stop the browning. Some dog urine is very concentrated, particularly in small dogs.  The urine burns the foliage and unless you are willing to follow your dog around with a water hose and wash it off immediately, it's likely to continue.
