I recently purchased a new home in OR.
It has hazelnut trees, however the shells are empty. They do not produce the meat. I do not have any history on the trees as the seller is no longer available to question. What can I do to the trees to make them produce useable hazelnuts.

What you describe has a term - blank hazelnuts. Blank nuts are in-shell hazelnuts devoid of normal kernels which result from defective embryo sacs, unviable eggs, failure of fertilization or embryo abortion at varying stages of development. Owing to the alternate bearing cycles for hazelnuts, poorly filled nuts may also result during an overproduction year, and poor kernel fill appears to be a heritable trait. Without knowing what variety you are growing, the condition is hard to diagnose. Hazelnut trees are wind pollinated so a second hazelnut tree needs to be in the vicinity. Without cross-pollination, no nuts will form. If you have more than one tree, the problem might be associated with an alternate year bearing cycle (you'll find out next year when you examine the crop). It could also be weather related.

I'd give the trees one more year to produce. If there are still no edible nuts, you may need a second tree on your property, which will mean you'll need to have your tree identified to you can find a second variety.

Let's hope your tree bears next year!

My husband purchased two hazelnut trees from the Arbor Day Foundation about five years ago. They grew so poorly the first couple years that he decided to move them. When he was moving them, one of the trees split in two. So, we now have three. They have grown a lot since the move and have produced blank hazelnuts the last three years. Should we cut them down and start over? What can we do to stop the blanks?
