One of the most popular onions in the country, yellow 1015Y gets sweeter as the bulb gets larger. A short-day variety, this Texas Super Sweet onion grows best in Southern regions.

The earlier you plant them, the larger they get, but they don't grow as big in the northern states. Mature 1015Y onions store for up to two months. Space plants 4-5 inches apart in rows 18 inches apart for conventional gardening, or 6-8 inches apart in intensive gardens.
