When to plant tomato in Valparaíso
In Valparaíso, tomato: sow seedlings around 10 July for the greenhouse and around 31 July 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.
