Definately Points to Ponder... Usually turf, especially sand, is very stable when it lives in a self-sustaining soil environment...
The only time I see runaway top growth in such soils, is when there is an excess of rain...
How many inches per week are you irrigating???
How often do you do the Sumagreen apps???
Now that I know that clay's texture(platelets) has nothing to do with water infiltration, percolation, or drainage,,, I wonder what does...
