Also need to know if I can transplant St. Augustine to areas of the the garden where the former owner's dog killed the grass and just dirt is there.

Thanks a million everyone!

Nadine's answer makes good sense to me (iron defeciency). Bought present home 6mo ago and started organic progam but have small areas in lawn where leaves are light green to yellow. Have highly alkaline soil. After researching for couple of months all the evidence points to "Iron Chlorisis". I am applying green sand today and I bet it works.

Chlorosis comes following heavy rains for the following reason. Normally without a lot of rain, the pH of our alkaline soils will actually decrease right at the surface. When the pH falls, iron is released from being bound up by the calcium. When the iron is available for the grass, it becomes dark green. When the rain washes through, the pH returns to 8.0 and binds the iron. Greensand is an extraordinarily chemically complicated material and has a way to counteract the effect.

Brenda, when you have a question that is not identical to the topic you are reading, it is always best for you to post a new topic to get the best reader response. People are reading this topic about yellow St Augustine, not about invasive weeds. I will give you a hint as to the solution: proper watering and mowing height.
