The Q&A Archives: Blueberries

Question: My blueberry bushes look terrible. soil ph showed 7 so we were told to add sulfate. they look worse and no berries at all. help

Answer: Blueberries require an acidic soil - 4.5 is perfect - 7 is just way to alkaline. Poor growth, lack of flowers and fruit and eventual demise of the plants is what you can expect in such high soil pH. You may want to dig your plants this fall and amend the soil with peat moss to help lower the pH. Replant and then plan to feed your blueberries with an acidifed fertilizer such as one formulated for azaleas and camellias. You can also topdress the soil with peat moss. Once the pH is lower you should see lots of healthy new growth and flowers on your blueberry plants. Good luck with them!
