Poole:

When you post a question like this, please specify your location. Location can make a difference in the advice you might receive on transplanting.

As far as I can figure out, you would like to transplant in four blueberry bushes you have found somewhere to join the four you already have growing near your driveway. Correct? Blueberry bushes are normally not considered trees.

If the plants you want to move are older, established bushes anywhere near as large as your 8-footers, you will have a very difficult time transplanting them successfully. Blueberries have very extensive, very fine, but shallow root systems. When transplanted, older plants usually never recover their original health and productivity, although they may survive in the new location. If you want more blueberry bushes close to your driveway, you would be better off purchasing young 2-year plants than trying to transplant older ones. If you want to transplant the old plants anyway, the dormant season is the best time to do it; never in mid to late summer.

If you have grass or weeds growing around blueberry bushes, you would be better off using an organic mulch than rocks. Weeds will grow right up through rocks or gravel, unless there is a weed barrier beneath, and even then they will eventually grow in. Rocks around the bushes would make it even more difficult to keep the area around them clear of weeds and grass.

Insects do not usually steal blueberries, but birds certainly do, and many of us have to net the bushes to deal with birds. The larger the blueberry bush, the more difficult this becomes, so you may want to consider pruning down your very tall plants to make netting easier.
