In a European survey of weed contamination in cereal seed in 1970, Holcus lanatus seed was found in 1% of samples.
H. lanatus is an indicator of poor soil, low grazing levels, and poor drainage.
It is tolerant of a range of soil pH, but grows best between 5.0 and 7.5.
It exhibits climatic tolerance over a wide altitude range, but severe frosts can kill it.
It does not survive trampling and puddling.
It can be controlled in some European locations by increasing available potassium and phosphorus, increasing stock, and improving drainage.
These remedies are not as effective in North America.
