GREEN MANURE ‘Annual Ryegrass’ Seeds
Botanical Name: Lolium multiflorum
Cool-season soil improver.
Adds lush green biomass fast.
Hardy annual grass for winter soil care.
Annual Ryegrass is an effective winter green manure that rapidly builds organic matter and improves soil structure. It germinates easily in cool conditions, producing dense, weed-suppressing growth. Ideal for breaking up compacted soil, feeding soil microbes, and preparing garden beds or paddocks for spring planting.
- Fast-growing cool-season grass, perfect for green manure or pasture renovation.
- Produces dense root systems that enhance aeration and soil crumb structure.
- Improves fertility and moisture retention when dug back into the soil.
- Highly frost-tolerant and ideal for temperate or subtropical climates.
- Competes strongly with weeds and can be mowed to maintain growth.
