This sporocyte is one of the oldest plant species and generally propagates by rhizomes that extend horizontally up to a depth of 2 m beneath the soil. Propagation with spores is also possible but occurs only in rare cases. This is a hardy plant that can be found especially in waterlogged soils. It can be found growing in practically any soil type and in all crops.
Horsetail [Equisetum arvense]
In early spring, yellow-brown strobili appear that die after the spores are shed (Picture 1). After blossoming, green, whorly-branched shoots appear (Picture 2). This light-dependent weed is supressed by rapidly growing crops that form a dense crop canopy such as dense grain crops. In later-emerging crops, such as beets and maize, horsetail may suppress the growth of the crop.
