GreenlyWhen to plant pumpkin in La Plata
In La Plata, pumpkin: sow seedlings around 23 July for the greenhouse and around 13 August for open ground; plant into a greenhouse around 29 August; plant out into open ground around 19 September.
Last spring frost around 30 July, first autumn frost around 17 June. Frost-free days: 322 days.
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.
