Rye Grass Root System Growth

Root System

• Ryegrass roots grow very deeply, and are dense and fibrous in structure. This dense root growth gives the grass superior soil holding capability and the capacity to rapidly establish in a variety of soils including rocky and wet. Ryegrass roots not only hold soil but also absorb excessive nitrogen and vigorously compete with weeds. The grass is frequently used for overseeding high-value crops, such as soybean and corn.

Growth Conditions

• Ryegrass grows well on nearly all soil types but best in well-draining, fertile, loam or sandy loam. The grass also establishes and grows in rocky, clay and poorly fertile and poorly draining ground. Grown under optimal conditions, ryegrasses are high yielding. Annual ryegrass is more prone to reseeding than is perennial ryegrass. Perennial ryegrass seedlings are less vigorous in growth than are annual ryegrass seedlings.

Annual Ryegrass Description

• Annual ryegrass is native to Europe and has a mature height of 2 to 3 feet. The dark-green grass blades are glossy and smooth textured. The inflorescence or seedhead is erect and has 35 to 40 alternate spikelets. Annual ryegrass is commonly grown in the Southern United States, mostly as winter forage for livestock. Annual ryegrass' flowering and seeding habit varies by latitude.

Perennial Ryegrass Description

• Perennial ryegrass is a native of Europe, North Africa and Asia's temperate regions. The grass has a mature height of 1 to 2 feet with stiff, narrow leaves from plant base. Foliage undersides are bright green, glossy and smooth textured. The seedheads grow in the form of long spikes with the seed containing spikes growing edgewise to the stem.
