Planning path

Succession Sowing Planner

Plan repeat sowing windows from catalog succession intervals, days to maturity, heat risk, frost risk, and extension succession guidance.

Default dated repeat plan

First sowing

French Breakfast Radish starts Mar 18 from the default April 15 last frost date.

Repeat sowings

Repeat sowings: Mar 25, Apr 1, Apr 8, Apr 15, Apr 22, Apr 29, May 6, May 13, May 20, May 27, Jun 3, Jun 10, Jun 17, Jun 24, Jul 1, Jul 8, Jul 15, Jul 22, Jul 29, Aug 5, Aug 12, Aug 19, Aug 26, Sep 2, Sep 9, Sep 16.

Last catalog-maturity estimate

Last catalog-maturity sowing estimate Sep 17 before the default October 15 first frost date.

Catalog repeat interval

French Breakfast Radish repeats every 7 days; use crop maturity and first frost to stop before the next batch misses the season.

Succession workflow

Small repeat batches

Sow smaller batches at planned intervals instead of planting the entire crop at once.

Replace spent crops

Reuse space after a short-lived crop is harvested, removed, or declines in quality.

Different maturity dates

Stagger harvest by combining repeat sowings with varieties that mature at different speeds.

Last useful sowing

Stop repeat sowing when days to maturity, first-frost timing, or peak summer heat make the next crop unrealistic.

Record the interval

Use each catalog entry's repeat interval as a planning prompt, then adjust for local weather and crop stress.

Regional succession checks

Pair catalog repeat intervals with regional planting windows, soil temperature, spring/fall resets, and local succession examples before filling beds in waves.

• Ohio Central Normal-Season Vegetable Garden OSU central Ohio checks for 7-to-10-day succession rows, regional timing offsets, and fall garden resets
• Minnesota Soil-Temperature Vegetable Garden UMN checks for repeat leaf lettuce, radish, and kohlrabi windows, soil temperature, and freeze-date timing
• Willamette Valley Oregon Garden Calendar OSU monthly calendar checks for repeated outdoor sowing, average-weather caveats, and soil thermometer timing
• Central Missouri Spring and Fall Vegetable Garden MU Extension central-column checks for cool-season repeats, spring/fall rows, and sweet-corn succession timing
