American White hazelnut
Hazelnuts prefer mild summers and cool winters (temperate climate) and do best when a number of conditions are met: annual rainfall of over 750 mm or additional irrigation especially while establishing after planting; and protection from wind and high summer temperatures.
• Pollination Group: Male and female flowers on the same tree don’t always flower at the same time so it is best to have other varieties present
• Uses: eating, cooking, roasting
• Harvest: nuts fall (February to March)
• Chill requirement: Requires about 1,200 hours of 5 to 7 deg C. Female flowers are vulnerable to frosts below -5 deg C especially when opening.
