When to plant pumpkin in Valparaíso
In Valparaíso, pumpkin: sow seedlings around 30 July for the greenhouse and around 20 August for open ground; plant into a greenhouse around 5 September; plant out into open ground around 26 September.
The dates follow the Greenly calendar: open ground a week after the last frost once the soil is warm enough for the crop, frost-hardy crops three weeks before it, an unheated greenhouse three weeks earlier, seedlings sown so they are ready on the day. In a cold year allow a week or two more.
