About 20 years ago I sowed some sweet chestnuts that I found in Southern England. One germinated and surpisingly to me it survived the first few winters. I therefore planted it out at the bottom of the garden. However, this area of the garden was overplanted and it became survival of the fittest (I didn’t really believe I would ever get chestnuts!)… It continued to grow slowly and survived one of our coldest winters ever around 2011 with only the tips freezing out (the whole root system down to the bed rock would have been frozen solid for 3-4 months). Seeing the exciting possibility of growing perhaps the furthest north chestnuts in the world, I gave the tree more space and planted a second tree (Marigoule) next to it (one tree can produce nuts, but yields are better with two). Then 3-4 weeks ago I noticed that the now about 5m high tree had produced a few male and female flowers which were opening at about the same time and I hope I now have a couple of chestnuts developing. However, it’s debatable if they will have time to mature in what has been a really cold summer here at 63.4 deg. N!
