Pollinator for a Jefferson Hazelnut #344029
Asked July 17, 2016, 11:51 PM EDT
I was disappointed to learn I had to have another tree to get any nuts from my Jefferson hazelnut. Having researched a little here, it seems that the ETA tree has the best overlap of flowering time with the Jefferson.
1) So is this then the best new tree to buy for pollinating my Jefferson?
If I'm wrong about needing another tree to pollinate, PLEASE let me know! I have just a small yard, and would not like to have to have too many trees....
2) Also, if my prevailing wind in Spokane in from the Southwest, should the Eta be placed southwest of the Jefferson, or the other way around????
3) How close should the trees be placed for best fertilization?
Thanks for answering, I'm anxiously awaiting your information!

Hello and thank you for contacting us with your question.
You are correct that you need another tree to get the hazelnut production you want from your 'Jefferson' tree. I'm sorry that you need to add another tree to your small yard.
As far as the best pollinizers, you are correct that 'Eta' is one of the best, as is 'Theta' This is because they are both late blooming trees, as is 'Jefferson' so their seasons match up well. One source lists Theta as the best match, but other sources say either Eta or Theta will work.
Depending on the layout of your yard, you want to put your pollinizer as close as six feet away from your 'Jefferson' hazelnut. That will help with pollination without being so close that you have trouble harvesting or working the two trees. The further apart you plant them, the less complete the pollination will be, and they should not be more than 50' apart.
If you can put the pollinizer upwind (in your case southwest) of the Jefferson tree, that would be ideal, however if the trees are close together, then the wind eddies around the two plants might still give you some pollination, even if the tree was not directly southwest.
I've copied a link to a fact sheet with more information on Jefferson hazelnuts, which you can find here: https://ir.library.oregonstate.edu/xmlui/bitstream/handle/1957/21957/em9028.pdf
