This German variety is a useful late pollinator for many other Hazelnut cultivars. Hall’s Giant can produce many catkins although nut quantities can be low.
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 nearby to improve pollination, in particular: Barcelona, Tonda Di Giffoni, Lewis
• Uses: eating, cooking, roasting
• Harvest: nuts fall (Feb to March)
• Chill requirement: Good yields require long cold periods of 5 to 7 deg C for about 1,200 hours. Female flowers are vulnerable to frosts of below -5 deg C especially when opening.
• Features: helps to pollinate other cultivars late in the flowering season
