The first nuts have appeared on the Hazelnuts I planted in 2012.
We had a really wet winter in 2016 and I suspect the Hazels benefited. Some plants put on a lot of growth. I replaced a few dead plants with new suckers taken from existing plants in the orchard. Gave most a prune in mid Winter too.
Pretty happy with how they have developed.
