Hi, During the summer noticed one of the potted Blueberries had sent up a very tall shoot, about 8ft, which I trimmed back to 5ft. Seem to remember the leaves were no different to the other plants, so just thought it was a very happy plant - variety Spartan. Just been removing them for repotting, this plant being right at the back and could now see that its a totally different trunk. Most of its growth must have been put on last summer as sure I would have noticed it before then, and it must like the very acid conditions and water I give them. Wonder if its an alien plant or a very large sucker if they are grown on root stocks ?
