Hand removal is the safest method of weed management when protecting pollinators is a concern. Perennial weeds require deep digging to remove the complete root system. Hand removal is intensive ...
Psathyrostachys juncea is a perennial bunch grass that grows in tufts that may be up to 1 metre (3.3 ft) tall or taller. The grass is long-lived and known to persist in cultivation for 25 years or more. The grass has a dense root network beneath each clump; there are no rhizomes or stolons. The roots can reach 3 metres (9.8 ft) deep into the soil.
“For cool-season grasses, cut about two-thirds of the way down—warm-season grasses should be cut to ground level,” says Zaber. “As you cut, hold the bundle steady with the tape, tilting it ...
This includes hand removal of grasses or by machine. In a five-year study conducted by Wilson et al. (2001) in Western Oregon, showed that mowing prairies of the invasive grass Arrhenatherum elatius allowed the native grasses Danthonia californica and Festuca roemeri to flourish and out compete the non-natives.

The grass grows from a thick root network. Plants have been noted to have roots penetrating over 4 metres (13 ft) deep in the soil and 3 metres (9.8 ft) laterally. The roots can grow 5 centimetres (2.0 in) per day. The first root to grow into the soil from a seedling can send out up to 60 small rootlets per inch. The dense root system forms a sod.
The deep fibrous root systems of switchgrass left a deep rich layer of organic matter in the soils of the Midwest, making those mollisol soils some of the most productive in the world. By returning switchgrass and other perennial prairie grasses as an agricultural crop, many marginal soils may benefit from increased levels of organic material ...
Paspalum dilatatum is a species of grass known by the common name dallisgrass, [1] Dallas grass, or sticky heads. It is native to Brazil and Argentina, but it is known throughout the world as an introduced species and at times a common weed. Its rapid growth and spreading rhizomes make it an invasive pest in some areas. [2]
The roots of buffalograss are significantly finer than those of most plains grasses, with a thickness of less than 1 mm (0.039 in). Despite their narrow diameter they are quite tough and wire-like. Though the roots may reach depths of 1.2 to 1.8 metres (4 to 6 ft) 70% of their mass is in the top 15 centimetres (6 in) of the soil and 81% in the ...
