Typical lawn weeds
Most lawn weeds are easy to spot, because they don't belong to the grass family. Others, in turn, although they are part of this family, however, they are not grasses, which we care about. They create large clumps that clearly stand out against the background of the entire lawn, spoiling his appearance.
The most common are cocksfoot, spikelets, weed and annual panicle. Fighting them is quite difficult and basically comes down to hand weeding. There is no herbicide, that would fight those grasses, without damaging the cultivated grass. Bird knotweed is also a common weed on lawns (Polygon's aviary), which usually occurs in loose turf and damaged areas of the lawn. Mosses are a damp problem, shady places with poorly drained soil. Moss is also favored by too low mowing.
Field hairy will quickly appear on the wet, acidic substrate (Luzula campestris) with long and narrow leaves covered with hairs. A common grass weed is the meadow clover (Trifolium pratense), which bumblebees like (other bees cannot get into their nectar). It is especially easy to notice then, when the grass turns brown – the clover areas remain green. Yarrow is also a popular lawn weed (Achillea millefolium) with soft silvery green leaves.
Sorrel is one of the weeds with a pile root system, common dandelion, plantain and thistle (the ooze). Fighting these weeds is very difficult, because their ability to adapt to various conditions, even so heavy, like frequent mowing, is huge.
If the lawn is established on acidic soil, among the grasses there is often a thread-like speedwell (Veronica filiformis). Although the tiny flowers of this plant are beautiful, it is a very nuisance weed. Buttercups thrive on wet acidic soils, and if the lawn is cut too short, common daisies appear on it (perennial wars).
