Perennial Ryegrass (Lolium perenne) belongs to the Poaceae family within the Lolium genus. Perennial Ryegrass is native to Europe, Asia and northern Africa. Perennial Ryegrass is also known as Ryegrass, English Ryegrass, Common Ryegrass.

Perennial Ryegrass displays a tall, grassy growth habit, reaching up to 2 ft tall with a spread of approximately 0.5 ft. Perennial Ryegrass produces small spikelets in clusters.

Leaf size: approximately 12 inches.

Lolium perenne requires watering every 3–7 days. Allow the top layer of soil to dry between waterings to prevent root rot. Reduce watering frequency during winter when growth slows.

Perennial Ryegrass thrives in full sun to partial shade.

Lolium perenne grows best at temperatures of 60–80°F. Perennial Ryegrass prefers humidity levels of 40–70%.

Well-draining loamy soil with good fertility. Good drainage is essential for Perennial Ryegrass to prevent waterlogging, which leads to root rot and fungal issues.

Feed Perennial Ryegrass every 8 months during the growing season (spring and summer) with a balanced fertilizer diluted to the strength on the label.

Pause feeding in autumn and winter, when growth slows, and never fertilize dry soil — water first.
