Water is critical to blueberry survival. Water shortage sets them back. The damage is permanent in recent plantings. Established plants may appear to recover but they, too, have permanent damage.

What state or country do you live in? Are there limestone rock formations in your area? When you water your blueberry shrubs, are you using hard water? If so, how hard is your water? Blueberry shrubs do not need very much nitrogen from the soil to maintain health. Therefore, adding fertilizer is generally not the cure for ailing blueberry shrubs. Usually, soil pH is the issue.

Hey Brandon

Im on the wagon with ericwi here. Fertilizer probably isnt as important as soil ph...as a matter of fact, I know it isnt. Instead of using a manufactured ph balancing agent, you might consider mulching with something natural like pine needles. Your blueberries will love you for that! If you have to use city/tap water, I might suggest you let it sit a day, possibly two, and let the chlorine and other "additives" evaporate. If you can catch some rain in a bucket, even better.

Good luck

If you are trying to acidify the soil further, you might try using ammonium sulphate for fertilizer. I use that in conjunction with Copperas on the advice of some posts by Jellyman. My shrubs seemed to do much better with those two products along with a thick hay mulch and very regular watering during the dry months. Our area is known for the hard water and that is unfortunately what my shrubs get watered with. Despite this, they still get bigger every year. My problem is that the deer find it necessary to "prune" my shrubs. I get some growth and they snap it off!
