Grow for profit

Find a sowing month whose calculated harvest sits inside a stored high-price window, then see whether that month is also inside the zone planting window.

Wholesale and retail vegetable prices fluctuate with weather and supply. This tool times a harvest against stored high-price months. It is not financial advice and it does not quote a price.

Methodology

How is the sowing month chosen?

The calculator adds the stored minimum and maximum days to the 15th of each sowing month. A sowing month is kept only when every month in that calculated harvest span sits inside one stored high-price window. Low-price months are not used. A span longer than the high-price window is left off.

What does the zone badge mean?

Ideal climate and market match means that sowing month is also inside a stored planting window for the zone. Off-season care or rain shelter means a planting window is stored and this sowing month is outside it. Planting window not stored means this crop has no placed month window for that zone.

Is this a price forecast?

No. Wholesale and retail vegetable prices fluctuate with weather and supply. The page times a harvest against stored high-price months. It is not financial advice and it does not quote a price.
