Garden Harvest Calculator

Turn plants, fruits each, and harvest weeks into totals and weekly pace.

What it does

Harvest gluts surprise gardeners who count plants instead of fruits. Six tomato plants at 20 fruits each give 120 tomatoes, which is 15 a week over an 8 week window.

The tool above takes plant count, fruits each, and harvest weeks. It returns total fruits, weekly harvest, and daily average, so giving, canning, and succession plans share one number.

This math fits even yields with steady picking. It does not fit flush and gap cycles, pest losses mid season, or varieties ripening on different calendars.

Extension gardening guidance frames the same planning: science based planting and harvest timing by crop and region. Counts here turn those calendars into kitchen totals.

Pick on schedule, not on sight. Regular harvests keep plants producing instead of stalling on overripe fruit.

How to use

1. Enter productive plant count.
2. Enter expected fruits each plant.
3. Enter harvest window weeks.
4. Read total fruits first for the season line.
5. Read weekly for the kitchen plan.
6. Read daily to set the picking habit.

Formula

plants

Producing plants of one crop.

fruits

Expected harvest pieces each plant.

weeks

Harvest window length in weeks.

Same crop must share the yield figure. Losses to pests need a lower fruits each entry. Succession rows need separate runs.

Worked example

Limits

• Even yields only. Flush cycles swing weekly reality.
• Ignores pest and weather losses unless entered.
• One crop per run. Mixed beds need split runs.
• Counts pieces, not pounds or nutrition.

Common mistakes

• Counting planted seeds instead of producing plants.
• Using catalog maximums as expected yields.
• Forgetting the harvest window shortens in fall.
• Mixing cherry counts with beefsteak counts.
• Skipping pickings so plants stall.
