If your plant looks healthy, I wouldn't be too concerned unless you truly have an accurate meter. I just went outside and tested my five blueberry containers, and they all read a perfect 7.0, just like everything else in my garden. Point being, the household-use meters are notoriously innaccurate. An occasional sprinkle of sulphur or "acid loving plant" fertilizer should fill the bill. If you have to repot, I would add pine bark to the mix. Misterbaby

By the way, you'll get bigger harvests with another variety nearby even if your first is labelled "self-pollinating." Misterbaby

I fertilize with miracle grow acid loving plant fertilizer every month or so and the PH seems to be fine. The plants are growing like crazy and no red/yellow leaves at all.

I'm pretty sure this helps keep the pH down. Give that a try and see what happens.

homertherat, when do you stop fertilizing that way? I have a bunch of new growth on my potted blueberry plants, so I think they should be fed now, I have not been regular with fertilizing this year. when do they normally go dormant?

When soil pH gets too high, blueberry leaves turn pale green, and eventually, they turn yellow. If your leaves are deep green in color, then your pH measurement is suspect. The plant is healthy. How are you measuring pH? What symptom is the blueberry shrub showing? If you have hard water, with significant lime content, the soil pH can be expected to rise over time. Do you have hard water?

rjinga, this is my first year growing them and I think I read somewhere that fertilizing them with acid loving plant fertilizer helps keep the soil pH down as well as fertilize the plants.

I assume that I'm supposed to fertilize this way until the season ends and start up again once they start growing again next season.

I'm pretty sure they'll shed their leaves within the next month, for me at least. I'd say they act just like other bushes, or any tree for that matter.

Assuming I reduce any excessive watering how long would soil sulfur take to work?

How much should I add to each 3 gallon container?
