Young chestnut tree.

Hope that has plenty of room,it's a sweet Chestnut I think.

Yes, Brian, they have plenty of room. I am now looking for partner which is registered (e.g. domestic tree, checked and free from oriental chestnut gall wasp, which was last year imported here from Tuscany with young chestnut trees). Something like registered partnership, lol.
I planted this one 4 years ago, just checking how it will grow. One old specialist recommended to me to add each year a bucket of marl from oak wood, what I ritually do every October with some leaves too.
It evidently makes the tree vigorous. So this year it has its first nuts (although they are "deaf" as we say, e.g. not real nuts) and it is time for a partner :)
Love this tree.

Did not realize they needed a mate to pollinate,several varieties grow wild in the UK always with pink flowers.
I know of one very old one you can collect the fruit from in Autumn but never seen a second one close by so possibly some are self fertile

Hello Brian,

I am not sure. If they are sweet chestnuts, they cannot self-pollinate. They do bloom, they even have fruits without another tree, but nuts are miserable...They require another tree to cross-pollinate. Single trees of any type do not produce nuts...

To me the nut is the fruit, Come Autumn I will try and remember to collect a few and post a picture.

OK.
