Here in New England, the fall color of in-ground blueberries is red. Actually, they've turned out, for ornamental purposes, to be a good substitute for the invasive burning bush.

I hope that's what it is...we've had some nights in the mid and lower 30's so that might be enough to trigger the color change. I was hoping to be able to monitor the plant's ph needs by watching for bronzing of the leaves, but that may only work in the spring and summer, if at all.

It's the cold. Even in the spring for us, blueberries show a lot of red in the leaves until the soil warms up. It looks like a phosphorous deficiency. Also, many blueberry plants will show reddish leaves when the leaves are young which will green out as the leaves mature. The red is more uniform when caused by cold. When the red is intervenal with green veins, that is usually more indicative of a pH issue. But even this symptom can occur with cold soil.

I just took a look at the leaves, on some varieties there are many leaves with lots of red, though few that are solid red. There are plenty of veins showing green(or a light color), and I only found one leaf where the red seemed to have overrun the veins. Misty seems to have the most leaves with red.

I have an Emerald that's opening up flower buds, lots of them, and also found some blossoms on a Star. Are these really early varieties or is this just a fluke.

The late season flowers can happen sometimes and may even develop fruit,but it probably won't taste very sweet.Brady
