Blueberry bush question

kimmee

I bought 2 blueberry bushes (well I say bushes but they weren't more that a few puny little branches really!). Anyhow, I planted them in 2 largeish pots in ericaceous compost and for a while they didn't do much but then they started sprouting and I thought that they were doing very well.

Yesterday I looked at them and one is now looking decidedly poorly. The pots they are in look absolutely sodden with all the rain we've had in the last week although they both have drainage holes in the bottom and I also put gravel for added drainage too.

I fed them with ericaeous feed a couple of weeks ago but haven't since then.

Can anyone suggest anything I can do to perk it up please? I would hate one to die because although they are both self fertile I was told that they would be much heavier cropping if I had 2.

Thanks for any advice
