Put pine needles around blueberries in Jan/Feb?
Hi - I am a big blueberry fan and have gotten a Elizabeth, Earliblue, BlueGold, and Rubel plant over the last few years. They have never done very well sad to say despite me getting a Ph meter and testing them. Last year I read on here about putting pine needles around their roots. I bought a bale and had saved them to work into the ground during winter dormancy. Lately I have been reading about people saying that the needles don't do much. Is it worth it to dig up the plants to put needles around them, or is there something else I should do with them? I am on a quixotic quest to see these guys really get going - thanks! Zone is 7a.
