it may not be self polanating if you can let us know the name we will proberly be able to help you,either post agine with more details or join the site and we can discus this and any other questions you may have.

Sounds like you've got its position right, but pears, as far as I know, need another pear nearby in flower at the same time for cross pollination, otherwise fruit will not set.

conferance are surposed to be self pollinating, Bamboo' I dont know others but we have people on hear that will .

My answer just quotes what my gardening bible says, Cliffo - it doesn't mention Conference varieties as being self pollinating, says you still need cross pollination. Fruit and veg are not my areas, really, as you know!

acording to T&M they are ?

What we need is someone on here who actually grows pears to answer - I don't always trust what the seller tells you - it is still buyer beware, and after all T and M just want to sell you stuff, don't they. But maybe they're right, I don't know, but it does sound like there's a problem with pollination for this Guest's tree.

Fractal, Andrewr, Owdboggy, were are you now that we need you,I was singing that lol.

Your pear tree may have plenty of blossom in the spring, pollination can be ruined when it's frosty, also as already said you need another tree to pollinate. I have cut a branch from a colleague's tree and placed it in the tree I wish to pollinate.

Two things come to mind.
Firstly, pears are notoriously slow to start cropping, typically ten years after planting before you get the first fruit.
Secondly, 'Conference' is partly self-fertile (according to 'The Fruit Expert' by Dr Hessayon. This means you will get some fruit from it without another tree as pollinator but the crop will be much better with another variety that flowers at the same time nearby.
Hope this helps.
