Aroostook
What's special about Aroostook
Extra-cold-hardy northern strain — germinates and grows in colder soil than most.
Growing this variety
Aroostook follows the same growing basics as Cereal Rye. Variety-specific maturity above; everything else below applies to the whole Cereal Rye family.
Germination
Spacing & depth
How to plant
Broadcast in fall, rake in, water once. Germinates in near-freezing soil and puts down a huge root system that outcompetes weeds and lifts compaction. Mow or crimp at flowering in spring and plant directly into the residue.
Grower's tip
The single most effective winter cover crop in cold climates. For grain, let it head out and dry down in summer — but be patient: rye takes 8 months.
Soil preferences
Firm, well-drained loam.
6.0–7.0
A modest nitrogen source in spring for wheat/rye; teff and rice prefer more.
Watering
1 in per week during establishment. Most small grains are drought-tolerant once headed out.
Overhead is fine. Rice paddies are the exception — constant flood.
Overwatered: lodging (flopped stems), rust. Underwatered: short heads, shriveled grain.
Prefers top-watering — Top-water (overhead or rain) — grains are wind-pollinated and tolerate wet foliage. Water deeply and infrequently.
Temperature tolerance
60–80°F (15–27°C)
40–65°F (4–18°C)
Winter grains (winter wheat, rye, spelt) overwinter through hard freezes. Spring grains and teff are frost-tender.
Container growing
Not recommended in containers
Grains need broadcast area — even a 10x10 ft patch yields a meaningful loaf's worth of flour.
Detailed harvesting
Cut whole stalks with a sickle or hedge shears when heads are straw-dry and grain dents but doesn't smash. Shock or hang to cure 1–2 weeks.
Post-harvest storage & preservation
Thresh in a pillowcase or against a screen; winnow chaff in front of a fan. Store cool and dry in sealed jars. Freeze 3 days to kill any weevils.
Culinary, medicinal & other uses
Bake, brew, mill for flour, sprout, or add to grain bowls. Straw is mulch or bedding.
Medicinal or traditional uses are shared for interest only — this is not medical advice. Consult a qualified professional before using any plant medicinally.
Seed saving
Most grains self-pollinate before the head fully emerges.
20 ft between varieties is enough for most.
The grain IS the seed — save cleaned kernels from your best-headed plants for next year.

From your kitchen — grow cereal rye from what you already have
Save whole ripe heads — grains are just grasses gone to seed.
- 1Harvest heads when they're straw-tan and the grain is hard (bite test: dents, doesn't smash).
- 2Cut whole stalks with 6 in of straw and shock or hang to cure 1–2 weeks.
- 3Thresh by rubbing heads inside a pillowcase or against a screen.
- 4Winnow by pouring in front of a fan; store cool and dry.
Storage: 2–4 years — grain seed loses vigor faster than most.
