Planning path
Cover Crop Garden Planner
Plan home-garden cover crops from soil cover goals, planting windows, fall timing, winter-kill behavior, termination method, crop-family rotation, and source-backed cover crop candidates.
Cover crop planning checks
- Pick the cover crop job first
- Choose whether the bed needs erosion control, weed suppression, nitrogen fixation, nutrient scavenging, organic matter, pollinator bloom, or a simple green manure before picking a species.
- Match species to the planting window
- Use spring, summer, late-summer, fall, and overwintering windows differently; early-harvested beds give cover crops more time to establish before cold weather.
- Plan termination before sowing
- Decide how and when the cover crop will be killed before planting the next crop, and allow enough time for residues to break down so they do not compete with seedlings.
- Use winter-killed covers when tillage is limited
- Choose oats, peas, radish, buckwheat, or similar winter-killed covers when the spring bed needs low-disturbance residue rather than a living stand to manage.
- Separate pest families from the next crop
- Use plant family and rotation context so brassica, legume, grass, and buckwheat covers do not accidentally host the same pests or diseases as the next cash crop.
- Seed thick enough for soil cover
- Prepare a clean seedbed, broadcast evenly, rake lightly for seed-to-soil contact, and irrigate if needed so the cover crop actually covers soil before weeds do.
Regional cover crop checks
Pair cover crop choices with regional spring, summer, fall, overwintering, frost, soil-temperature, and bed-reset checks
- Connecticut Crop Planning Calendar Vegetable Garden UConn checks spring, summer, and fall cover-crop sowing windows, frost-aware resets, and soil-test cleanup timing
- Willamette Valley Oregon Garden Calendar OSU checks September-to-November oats, rye, vetch, and fava-bean cover windows with average-weather and soil-thermometer caveats
- North Carolina Piedmont Season-Window Garden NC State checks June-to-July warm-season succession cover crops and September-to-November overwinter cover-crop planning
- Lower Peninsula Michigan Garden Calendar MSU checks Zone 5a-6b timing shifts, first-frost ranges, soil-temperature cautions, and September cover-crop rows
