Can't remember exactly how long ago I planted them, but bushes are now 8 or 9 feet tall. Guessing 6 years ago. Things I did right: Got a good mix of cultivars for pollination. Used commercial cultivars developed at Oregon State University to be immune to Eastern Filbert Blight. I do have one cultivar not developed there but known as an excellent and DR variety. What I did wrong: Planted them in too shady of a place. Euros are not as shade tolerant as Americans. I feel that the shade is one reason my fruiting has been delayed. They are at the edge of a woods and getting 1/2 day sun or less. This would be fine for Americans, but not great for Euros. Important Facts: I can easily start these at other places by layering them. I'm already doing it. They are on their natural roots, so no problem. Already getting some new ones started in sunny places. Euros are bigger than Americans. That's why they are grown commercially. My crops are not large this year, but one of the bushes is pretty loaded. Ironically, the most loaded one gets the least sun. Americans are immune to EFB, but run of the mill Euros are affected. That is why it's important to use cultivars developed for immunity. Mine look very healthy.
