Bluecrop Blueberry - Leaf Image Symptom Checker

Posted by NorcalChileGrower 8 (My Page) on

So a little over a month ago I started 4 containers of Northern Highbush blueberry (in zone 8). Two are Bluecrop, one is Darrow, the other is Spartan (I'm aware I'm in zone 8 and asking for trouble with Northern varieties). They were potted in a premixed "Acid Potting Mix," and are mulched with redwood. None have really taken off. But now recently all of their leaves are starting to turn red.

Checking their PH gave me an alkaline reading of about 7. After seeing their condition decline, I just yesterday repotted them all and amended the soil with cottonseed meal and sulfur.

The provided image of the top of the leaf is extreme, and not typical (yet), and I suspect might be a fertilizer burn, but the image of the underside of the leaf is what most of the outside of all of the leaves on all of the plants look like.

Any ideas?

Not fertilizer burn.

Instead, environmental stress, which may be as "simple" as short of water while trying to establish a root system.

One or several off-color leaves can be normal whereas the distribution on a plant can be very telling as to the underlying cause.

So, in the future, please post an overall picture of the plant concerned as well as an affected leaf/branch.
