Hello all, I’m very very new here and to gardening. Can anyone tell me why my blueberries are turning purple after planting? I bought the bushes at a local nursery and planted beside each other. One still has green-ish bulbs but the other started turning purple? I’m not sure if it’s supposed to do that yet, or if my soil mixture isn’t right. I mixed pine bark soil conditioner, in ground miracle grow soil, and holly tune. Please help!
