I'm looking at Trees at the moment for my garden.

I saw an Oak with a Silver Birch rootstock at a Nottinghamshire Garden
Centre and was wondering if anyone can fill me in with info on a rootstock
of this nature, the growth changes etc...

I asked at the centre and they did not give much info apart from a reduction
in size.

I've had very little success in finding info about this on the web.

Thanks in advance,

Swiss
