Cereal Rye (Winter Rye)
Secale cereale
Family Poaceae
Grown as an annual
The most forgiving and useful cover crop — you can sow it shockingly late in fall (in cold soil where nothing else will sprout) and it still establishes, protecting bare soil all winter, mopping up leftover nitrogen, suppressing weeds, and driving deep roots that break up hardpan. In spring, mow or crimp it and plant right into the residue mulch. Not ryegrass — this is the grain of rye bread.
