Action plan

Can I plant this now?
Use your local last-frost, first-frost, and soil-temperature checks before treating this crop as plantable today.
Start indoors or direct sow?
Direct sow into the final bed when the soil temperature, seed depth, and moisture are ready.
How much space?
2 inches in-row spacing, 6 inches between rows, and 1 inch seed depth.
Best companions?
Use crop-family rotation first, then pair with compatible timing, spacing, and canopy size rather than relying on a simple companion chart.
Common failure modes?
Plan termination before planting vegetables; rye resumes growth in spring. Usually relies on cool-season moisture after establishment. Tolerates many garden soils.
