The leaves on one of my blueberry bushes are turning red then dropping off. Anyone any ideas?

Blueberry plants react to extra cool weather during the growing season by leaves turning red, and leaf drop normally follows as the plant thinks winter is coming.

Are you currently experiencing cool/cold weather? If so, nightly fleecing might help.

so will giving the plants an extra feeding. An all purpose fertilizer would work, sprinkle it on the ground and scratch it in. Or, some rotted manure and BFB watered in along with fleecing might help the plant to get growing again. It's been an odd weather year so many new plant problems are cropping up.

Can you use ericacious plant food (designed for, according to the label, azaleas and rhododendrons) on blueberries?

It is perfest 

PS My plants at the plot have got some red leaves too, but seem fine other than that. Ones in the nice warm sheltered garden have not  (See Trillium's post above)

I took two healthy well established blue berries from our nice warm sunny patio and planted them (correct soil etc) on our exposed windy cold allotment and the turned red, all leaves have dropped off. I need to wait until next spring to see if they have survived, but I dont like my chances.

My wife is not happy! They are were her favouites!?!

As already suggested, fleecing might have helped but I guess its too late now?

Most likely. They're deciduous plants and may not leaf again this year, but not necessarily die even though they're bare.

Put them in a more sheltered area, give them a nice manure or comfrey feeding, water well and see what happens. You definitely won't get a crop this year but you might get leafing and some new stems.

Blueberries are tougher than they look 

Losing their leaves is a survival mechanism, remember
