I have two blueberry bushes, two years old, in individual pots with ericaceous compost. Both bushe started the seson well with plenty of flowers and leaf growth. Bluecrop has now gone into "autumn mode", the leaves turning colour and falling off, with the fruit very small a wrinkled. I scraped the bark and it is still green, so I don't think that it has completely idea. Earliblue, the other plant, is looking very lush. Any ideas?
