Clue 2 How are wild berries harvested in the Netherlands? Picking bushes is completely allowed. The collection of wild plants, fruits and berries on a scale approaching the industrial one is considered great business and is subsidized by law. You can collect a small plastic container with a capacity of 250 ml, but baskets, buckets, large plastic bags are excluded. The Dutch are generally very kind to nature: when picking berries, you need to make sure not to break the branches and not spoil the bush.
