Hello Barrence - I have no experience with this plant but since you have not yet had an answer I'll stick my oar in. I just googled the name and it seems that it is a good choice for growing on the Island - mild temps and salt winds. I know the climate - I grew up across the water from you. However, it seems to get quite large, needs severe pruning and is spiny. I'm not sure those pots will be big enough.

Thanks Flora I realise that you can prune the tree. It is whether you can pinch out the centre growth.

I hade searched internet but mauinly dealt with pruning rather than training (Shaping) I found it on this site

Thank You for responding
