Question:<\/h3>\n

\"hghbush<\/a>I have several blueberry bushes that are developing reddish\/purple leaves and berries throughout the summer. This affected the berry bushes last year as well. I am struggling to diagnose the cause and come up with a remedy so I’m hoping to get some guidance. I have had some suspicion of fungal disease and have tried using a biofungicide which does not seem to help. They are planted in loamy soil with compost underneath them and mulched with cedar and compost. I have also tried to supplement with miracle grow to address any nutrient deficiency and have added citric acid to help lower acidity<\/strong>.<\/p>\n

Thank you for your photo and question about your highbush blueberries. It looks like you have nice fruit this year<\/p>\n

Blueberry plants generally do not require high amounts of fertilizer, so hold on adding more for now. Fertilizing after mid-summer can create tender new growth that won’t harden off before winter.<\/p>\n

Blueberries need a specific pH in order to take up nutrients, so we recommend testing your soil<\/a>. Kits can be picked up at your county Extension office or we can mail one to you. When you fill out the form, use Crop Code #410 adding a note about how many plants you are growing. You’ll get recommendations from the Maine Soil Testing Service<\/a> on how to adjust the pH and what you need for nutrients if needed.<\/p>\n
