Hazelnuts or hazelnuts?Whatever the name, they are fun to grow | Lifestyle

These European hazelnuts are commonly referred to as hazelnuts. These are the nuts you will find in supermarkets and they are generally grown either in the Mediterranean region of Europe or in the Pacific Northwest here.

A disease called hazelnut blight has historically prevented people from growing hazelnuts in the eastern United States. This endemic disease has little effect on our native hazelnuts, but can have devastating effects on European hazelnuts.

The name “withered” says it all: collapse and death of branches, wrinkled leaves still clinging. A more obvious symptom is the raised dark lines of ridges that run along the branches. The disease has a long cycle and incubation period, so it can remain undetected for years. It can be 10 years before the tree is killed.

Easy workaround for illness

Pruning and spraying are two ways to deal with withering. But even better is to plant resistant varieties to address the problem of most pests in any plant.

Years ago, blight found its way to a commercial Philbert orchard in the northwestern Pacific. It had the positive effect of encouraging the search and reproduction of high quality Philbert varieties that would not yield to disease.

Hall’s giants and Willamette were found to be somewhat resistant early on, and the former variety came to my garden. After a while, Luis, Clark and Tonda di Giffoni arrived. All three are even more resistant to wilt. And all three found their way in my garden. Recently, varieties of gamma, delta, epsilon and zeta have been bred. They will be in my garden soon.
