What to plant in Chubut in September
Early spring in Chubut brings cool averages of 9.7°C and low minimums near 4.6°C, limiting outdoor sowing strictly to cold-hardy vegetables. With November showing averages of 17.3°C and minimums of 10.9°C (meeting the anticipation threshold 8 weeks ahead), gardeners can safely initiate warm-season crops in protected indoor seedbeds while establishing hardy greens and roots directly outside.
