Happy New Year everyone, we have 2 American Hazelnut trees that are mature and quite large (8 m tall and 8 m wide) we get very few hazelnuts from them. We estimate them to be 40ish years old. I’m wondering if they are both the same cultivar and that is why we are getting so few nuts. I’ve read that you should have 2 different cultivars in order to get a decent harvest. So here are my questions, 1. Will having 2 different cultivars give us a better harvest? 2. How can we determine which cultivars we have? Is there a place where you can send tissue samples away for testing? thanks everyone!
