    Customer had a soil analysis done of his lawn and it came back with a ph of 8.0. I wasn't sure what to tell him. Is there a way of bringing the ph down or is this not a concern. Thanks

    No need to. Mine grows directly into caliche (limestone rubbles) and it seems to do just fine but i use greensand to keep green color better....

    It grows just fine at 8 we have it around here and 8-8.2 is typical for both soil and irrigation water. Sulfur applications will bring it down temporarily. Compost or peat topdressings will have a more long term effect.

    Up here, when my ph gets over 7, it gets florescent lime colored, and won't uptake any nutrients. Have to knock it back down with elemental sulfur before the temps get too hot.
