Hello folks. I'm pretty much a new guy. My hands on experience is minimal and have been trying to read as much as I can.
Anyway I bought a blueberry bush last weekend and dropped it in the front of my house about three days ago. I added some 10-10-10 fertilizer and some fresh pine needles to the soil but the PH is still close to 7 and I should be high 4's or low 5's. Do I start adding more fertilizer and needles or give what I've already put in there more time to "work itself into the soil"?
Furthermore, I purchased one of those $7 ph meters from Home Cheapo. Are they accurate, reliable?

Thanks,
Benjy the noob.
