In particular, Bramley doesn't produce viable pollen, so not only does it need a pollinator, you need a second pollinator to pollinate the pollinator.

There again, if there are other apple trees on the allotments, you may get away with it, if they flower at the same time - but you'd be dependent for your apple crop on other people's decisions.

I'd want to know the rootstock, because this will determine whether you get a small tree that needs staking all its life, or a huge tree which will shade out your entire allotment and that of your neighbour as well.

And I suppose I'd also be wondering whether I really want to buy a Bramley, which is readily available in the supermarket, or whether I'd prefer to buy some other cooking apple with a different taste.
