Can onions be planted in October?
Direct seeding can be used successfully for commercial bulb onion production when stands are well managed. Seed is typically planted in late fall or late winter (approximately September 10–October 15 or January 15–February 25, depending on location and weather). Onions require 90 to 100 days to mature from seed, which is around four months. We start seeding our vegetables shortly after the New Year and then in spring we transplant them into the garden. Seed starting trays come in all different sizes and depths.
