leaves on blueberry bush changing color

[Grimir]

I am wondering why leaves on some of my blueberry bushes are changing color. They are becoming yellow to brown and in the middle of them are green line. I red in one book for BIO Garden that it might be cause of Magnesium deficit. My bushes are 2 years old and are Blue crop sort.


Cheers.

Are your bushes in pots or in open ground Grimir. You do seem to be having a lot of trouble with your blueberries.

Well they are planted in my garden in ground, i didnt treated soil before planting to become acid. So i got peat moss and i puted in every hole lots of peat moss, and i have liquid fertilizer for acid loving plants. As i red on the manual of that fertilizer, it says that it has inside 2 types of nitrogen. One of them is nitrit nitrogen and i as i remember i red somewhere that it is not good for blueberries, so i am afraid of using it on them.
I think i found the problem and it is Chlorosis, it says in the book that problem is too high PH of soil, that it is not enough acid. Recently i mulched my bushes with small branches and leaves of pine, and it seems that they are getting better.

Cheers.

If you are having probs grimir & the plants are not in flower or fruiting, I would be tempted to get them in ericaceous compost PDQ. That's not to say it is the right thing to do or the right time to do it, it's just what I would do.
