Instructions Chevron Down Chevron Forward

Start Sweet Spanish Yellow Utah Jumbo Onion seeds indoors 8-10 weeks before transplanting outdoors. When transplanting, clip plants to 3" and plant 2" deep. Or, sow directly in the garden when the ground can be worked, placing 2-3 seeds per inch. Thin to 3" apart when the plants are 6" tall. Harvest onions by pulling bulbs when the tops are brown and dry.

Planting Depth: 0.5"

Seed Spacing: Sow Sweet Spanish Yellow Utah Jumbo Onion seeds roughly 3" apart in rows, keeping each row approximately 18" apart.

Nutrient Care Instructions: Apply SUPERthrive once per week. Soak in solution of 1/4 tsp per gal for 15 min. or longer depending on size and type.

Suggestions Chevron Down Chevron Forward

Fertile, moist soil enriched with compost is best for onion production. Onions ward off many insect pests around lettuce, cabbage, and carrots. Use thinnings as green onions.

At Ferry Morse, we are proud of our non-GMO & guaranteed fresh seeds.
