How do weeds influence turf growth? Provide some examples
What will be an ideal response?
One of the greatest influences that weeds exert on turf is direct competition. This competition is generally for water, light, nutrients, and space. The competition is particularly strong under conditions that do not favor turf growth. This might be a situation of high or low pH, high or low moisture levels, or other stresses. High levels of moisture and nitrogen encourage germination and rapid growth of annual bluegrass at a rate greater than the desired turf. Soils with a low pH allow rapid development of plants like red sorrel while compacted soils slow turf growth allowing species such as knotweed and crabgrass to flourish.
