We have a hazel nut plant we did not know was there . . . until it suddenly this summer produced a several dozen embryo nuts, only one or two per branch.
This plant has a dozen stems, seeded itself anything up to 10 years ago, and now stands about 2 metres high and 2 metres wide. What can I do to encourage it to become a high- yielding hazel nut tree ?
I forget the zone number but Ottawa, Canada, is pretty cold for 5 months of the year.
