Spinach succession planting plan

Use the reviewed weekly interval to organize separate spinach sowings, then review heat and protection before retaining the whole sequence.

Growing purpose

When enabled, the earlier of your end date and the source reference sets the last possible batch. Turn it off only to make a deliberate custom schedule.

5 sowing batches

Spinach leaves · 7 days

  1. Batch 1 Direct sow
  2. Batch 2 Direct sow
  3. Batch 3 Direct sow
  4. Batch 4 Direct sow
  5. Batch 5 Direct sow

The end date is inclusive. Cross-year schedules keep the correct calendar year.

Next would be May 6, 2027; it is after your end date and is excluded.

The source stopping reference (Oct 1, 2027) is applied. Your own earlier end date still takes priority.

Sources and conditions

The source’s autumn boundary excludes protected cover. Heat can interrupt a summer sequence even before that boundary.

  • The succession source assumes standard growing practices. Variety, heat, daylight and protection can change useful sowing dates.

This is the source chart’s latest-sowing reference under the stated conditions. It does not promise maturity or a harvest by that date.

  • The succession source assumes standard growing practices. Variety, heat, daylight and protection can change useful sowing dates.
  • The source’s autumn boundary excludes protected cover. Heat can interrupt a summer sequence even before that boundary.

These are source-specific stopping references. They are not a promise of harvest before frost. Review crop, variety and cover conditions.

These sources describe particular climates and growing methods. Use the conditions alongside the numbers.

A weekly schedule is conditional

The chart supplies a seven-day interval. The Minnesota guide separately warns that summer heat limits a continuous spring supply. A date pattern therefore needs a local-condition review; it should not continue simply because an autumn boundary is still months away.

Read the protected-cover exception

With a user-entered first frost of October 15, 2027, the chart’s two-week-before reference falls on October 1. Its rule excludes protected-cover extensions. It says when the general sowing sequence stops, not when leaves will be ready to harvest.

An inclusive end-date example

A user-selected start on September 3 produces September 3, 10, 17, 24 and October 1 at weekly intervals when that boundary is the end date. If a new batch starts after the selected end, the correct result is no dates, not a shifted or invented sowing.

Questions growers ask

Is this a special baby-spinach rule?

The source row is labeled spinach. This record does not rename it as a baby-leaf rule or imply that a specific harvest stage is guaranteed.
