Orange Spots

I have two blueberry bushes, one quite heavy with fruit, waiting to ripen and this week I have noticed orange spots on the leaves, and I looked it up on the internet and it says rust, but it describes it as the whole leaf being affected, but on mine the leavesare only orange at the tips, anyone with any idea, I have removed all affected leaves and burned them, just in case. The other bush is not affected. Any ideas please?

 

You could try a search for leaf scorch, sometimes caused by water droplets and strong sunlight, that's the only one I can think of hope you get some more ideas.

 

I have two blueberry bushes and do not have a single fruit on it this year, plus it has got yellow leaves in places, some are just tipped yellow, others are sort of speckeled yellow.:(

I know I had better do a bit of internet research on blueberry growing pretty soon, else I will ahve wasted the money buying these bushes.

 

Thanks t digger, I think you could be right about the rain, as I have moved it under shelter, and no more orange spots have appeared.

 

Have you fed the plants with anything this year?
