Onion Seed Planting Information:

Onions seeds should be planted indoors 8 to 10 weeks before ground can be worked. Onions must be planted in seed starting mix at a constant temperature between 70 - 75 F. You can also plant seeds directly in the garden but the soil temperature should be warm 75 - 90 F. Spring planting of onion plants should occur as soon as soil can be worked. Keep free from weeds. You need long sunny days to grow large onions. Shallots are very close to garlic and are very easy to grow. Plants can grow 8 to 12" tall.

Soil Requirements:

Requires fertile soil in a well drained location in the garden. Apply much and grass clippings, or straw around base of plant.

Water Requirements:

Keep seedlings and transplants consistently moist, but not waterlogged. Water well during dry and hot spells.

Fertilizer Requirements:

Use RootBlast, Vegetable Alive, and Slow Release Fertilizer when transplanting outdoors. Apply Miracle Gro every 2 weeks.

You can harvest onion for their green stems (scallions) at anytime. Cut the green stems with garden scissors when tops are 4 - 8" tall. For bulb product, let the tops dry up themselves before digging them up. Spread bulbs on ground for 3 to 5 days to cure.
