Bobby, Some plants don't like to have water on their leaves...it can give them sunburn in the hot summer sun. Tomatoes are another one...I was told to always water them at the base. I can't help you on the limestone question, but I remember the guys at Belleclare definitely made a point of saying 'Granular' limestone only. They were really big on that advice.
