When are nuts harvested?
Hazelnuts, also known as “filberts”, thrive in regions of the world where the climate is cool and humid. Originally, a hazelnut tree starts to produce fruit at the age of 4. However, it does not really become productive until it is 7 years old. When the hazelnuts reach maturity, their involucre begins to dry out and turn brown. Ripe fruit can be recognised by its brown colour.
In some varieties with a very open involucre, the hazelnuts may fall to the ground by themselves. This is a message that it is time to harvest the fruit from your garden hazel. In general, hazelnuts ripen between the end of September and the end of October of the year.
However, there are early varieties that ripen as early as the end of August. These are mainly the “Aveline de Piémont” and “Butler” varieties. The harvest of hazelnut fruits continues in October with the group of varieties “Bergeri”, “Nottingham” and “Web’ s prize Cob”. The fruit of the hazelnut trees of the “Merveille de Bolwiller” and “Ferwiller” varieties only ripen at the beginning of November. Some hazelnut varieties may ripen early or late.
The walnut tree grows well in temperate climates where the sun is always shining. To enjoy the majestic appearance of the walnut tree, you can plant it in your garden. The husk of the fruit may turn brown, crack and the nuts start to fall to the ground. This is a signal that nut picking can begin. As with hazelnuts, harvesting of walnuts starts from mid-September until October.
The early varieties such as “Ronde de Montignac” or “Marbot” are harvested in September. On the other hand, the walnuts of the “Mayette”, “Meylannaise” and “Verdot” varieties are only really mature at the end of October.
Walnuts, hazelnuts, almonds and cashew nuts are dried fruits that can be stored for a long time after harvesting. In general, the shelf life of nuts and hazelnuts is 6 months, but this can vary depending on the species.
