Growing Blueberry Plants From Start in Containers
I want to know what soil should I buy for planting blueberries in containers? I have used top of the line potting mix and added water with plant food for acid-loving plants, but my plants are not doing well at all. In fact, they looked better when I recieved them in the mail. I also added coffee grounds and Holly Tone for acidic shrubs and trees, and mulched with pine needles, but still it's getting worse. I have checked the pH and it is still 6. 7. I can't get it lower no matter what I do. Can I transplant and start all over with different soil mix? Planted only 6 to 8 weeks ago and maybe I can save them.
