Colloquial term (also known as weeds, or the neutral-sounding weed) for various plants that can occur as spontaneous accompanying vegetation within a crop, for example in a vineyard. They are not deliberately cultivated, but arise from the seed potential of the soil or via seed dispersal. The criterion for "weeds" is that such plants enter into unwanted competition with a deliberately cultivated crop in terms of nutrients, water and light. From a biological point of view, however, there is no such thing as a weed, because a vine in a rose bed or a rose in a vegetable patch can also be undesirable.

Weeds: 1 = stinging nettle, 2 = dandelion, 3 = thistle, 4 = field bindweed, 5 = sorrel
