Hi Csarina,
Yes, Symphoricarpos albus var. laevigatus (AKA Snowberry) can easily be trained to form a dense hedge. I would cut yours back hard, to around 30cm or so, making sure there are plenty of active growth buds remaining or you'll just get lots of suckering growth and loose all of the original stems. Then, after they have re-grown you can keep them pruned to the size that you require.

Thanks for that. There are bits of the blessed thing coming up in the bed in front of the bushes, are they suckers or do the roots 'creep' the bottom 2/3rds are just stem, the growth is on the top, the stems are more like trees rather than bushes, will the growth break from there again, if it isn't going to break I am going to kill the roots and try something else. I want a hedge of some sort between us and our neighbours.

I had the same problem with a Snowberry Csarina, I planted it to cover an unsightly part of the garden, which it did, but it grows at a scary rate, I had some advice from the guys hear on GoY best advice I have had, and I know it sounds extreme, but the advice was to kill it, which I did before it got too out of hand, I'm still deciding what to replace it with, but at least I'm not worried about it invading everywhere anymore!

What did you use to kill it with????? its not particularly pretty and the flowers are quite insignificant, cannot see OH digging it out.....

Csarina.

Roundup stump and root killer, hacked as much as I could leaving as many leaves as I could also, this is systemic, so broken woody surfaces means the weedkiller can penetrate more easily.
