Some of the edges of the leaves of my dwarf blueberry bush have turned brown. Does anyone know why?

Hi Violets22, looks like wrong growing condition to me, maybe too dry as it is in a pot, need a feed or too sunny position, how long has it been in the pot, even though it is a dwarf shrub, it will need plenty rich compost/manure which will also help retain some moisture, but also look for any bugs on the leaf as some nibbled edges can cause this, but my money Goes on improper conditions, hope this helps you.
good luck, Weenel.

Looks to me like it has chompers. I noticed that some of the leaves look puckered, like the ones at the upper left. Mites perhaps, or some other really small suckers. But judging by the small size of the new leaves, the plant was already unhappy. I would prune it back to remove all the unhealthy parts, as well as anything laying on the soil. Give it a thorough water bath and then when dry, spray with insecticidal soap to control the chompers. Fertilize lightly with an organic fertilizer. Compost would be the best but the plant is already deep in the pot.

Thank you all for your comments. I think the suggestion that the plant was in too sunny a position may be right. All my blueberry plants were in full sun because the the plant info stated that they needed full sun. When they were in full sunlight, they all suffered some brown edges, but this plant was the worst. However, after I moved the plants to partial shade, no new brown leaf edges appeared.

You don't say what zone you're in or where you live, but if you live somewhere that has hot summer temperatures, often plants that say they like full sun will actually prefer a bit of shade during the hottest part of the afternoon.

Thanks for the comment. I live in Florida, so these do need more shade.
