We have about 5 pink lemonade blueberry bushes that did amazing last year. This year the bushes are full of green berries that are turning brown instead of pink and falling off the bush. We mulch with pine straw and ground up pine cones and use rabbit manure and compost to feed the plants. What could be causing this? It looks like we will lose our whole crop at this rate. Photo is of two berries that went from green to brown.
Hopefully the blueberry problem you had last month has been resolved. Without the plant picture and further information it is hard to tell what is the problem. It could be due to plant nutrition (as I expect rabbit manure and compost both raise the soil pH and hence plant not being able to absorb proper nutrition from the soil) or some kind of disease. I looked up online for any possible blueberry fruit disease that turns the fruits brown and the only information I could gather was a disease called "Mummy berry" that causes by fungus Monilinia vaccinii-corymbosi and infection spreads more in a cool and rainy years but not in hot and dry years usually in the month of May. Conidia produced on this infected tissue will subsequently infect blossoms and young berries. Infected berries are tan or pink in color and the hardened berries shrivel and fall to the ground. Was your area in GA more cooler and rainy in May this year and the berries hardened and fallen to the ground beside turning brown? Is your blueberry's symptom was similar to this website? http://blueberries.msu.edu/uploads/files/Mummy%20berry.pdf
Most of the times your county's agriculture extension service can help identifying the problem and may have some solutions.
