You can harvest walnuts in autumn and stock them up for the whole winter. But harvesting alone is not enough. We’ll tell you what to look out for.
Harvesting walnuts – when does that work?
Walnuts are healthy and delicious. In addition, they can be stored well and for a long time. What could be more obvious than stocking up for the winter in autumn? If you have the opportunity, you should use it.
Walnuts ripen in the fall. They can be harvested from mid-September to the end of October. Strictly speaking, the term “harvest walnuts” is not so apt. Because you shouldn’t harvest walnuts from the tree. Rather, you wait until they fall from the tree on their own and collect them. This way you can be sure that they are really ripe.
Harvesting walnuts – this is the best way to do it
When walnuts grow on the tree, they have another, softer shell in addition to the hard, woody shell. This shell is initially green. When the walnuts are ripe and fall from the tree, the green shell bursts open. Later it turns black.
Especially in damp grass, the outer shell can quickly start to mold. Therefore, you should collect the nuts as regularly as possible. Preferably daily. It is best to sort out walnuts that are moldy or infested by caterpillars immediately.
Clean and dry walnuts
After collecting, you need to clean and dry the healthy walnuts. Remove the green outer shell by hand. You can also use a brush to remove any residue that gets stuck.
Drying the cleaned walnuts is not difficult. To do this, place them in boxes or baskets in a single layer if possible. It is best to turn them once a day or mix them vigorously. It is important that the walnuts dry as quickly as possible. Otherwise you run the risk of the walnuts starting to get moldy. An airy place with 20 to 25 degrees is best. If you dry the nuts outside, you should put them inside in the evening. Otherwise they will get wet again during the night.
The walnuts are dried enough when they lose about 50 percent of their weight. This is of course a bit difficult to control. The drying time is about three to six weeks.
Storing walnuts
After the walnuts have dried, you can store them for several months. Make sure that they are stored as dry and airy as possible. High humidity can lead to mold. It is best to hang the nuts in bags or nets.
