dont need water everyday, water every other day is better. take some soil sample to the county extension they can run the soil test for you free of charge. Ph 4.8-5.2 are best for blueberries. use some peat when plant blueberries and adjust the ph with sulfur. Normally it took more time time to lower the ph than high it.

FYI, lime juice has the lowest PH (around PH2.1)among common beverages. Lime juice lowers while lime stone raises pH. Please do a little bit research before attempting to post any useful information.
