how do you grow big onions?

Answer 1

Answer 2

As Nola said to get big onions, bend over the tops, I usually do it when they are about 12 inches tall but I am sure it doesn't matter there. The reasoning behind this is to force the growth into the bulb, the onion, itself.

Answer 3

The earlier you get your onions in the ground in the spring, the better the chance they will have to grow nice big bulbs

Plant onion bulbs or seeds as soon as the soil is dry enough to work. March through April are good times to plant summer harvested onions

To help eliminate difficulties with onion seed germination, or to avoid waiting for soil to dry out or warm up in the spring, start onion seeds in flowerpots indoors. Transplant these when the tops are two to three inches tall.

Use good potting soil, a container with a drain hole, and provide plenty of light. Seed-planted onions need a longer period of development than with onion sets.

Plant onion seeds a half-inch deep at a rate of one to five seeds per inch. Thin seedlings after they are established. For large dry onions, thin seedlings to two to three inches apart; for medium-sized onions, one to two inches; and for boilers and green onions, a half-inch to an inch. The key to getting good seed establishment is to keep soil moist so it doesn't form a hard crust.

Onions can be grown in almost any type of soil as long as it has good fertility, drainage and tilth. Onions respond to both compost and commercial fertilizers.

A handful of complete fertilizer applied along the row at planting time will get the plants off to a good start. A good compost or organic fertilizer will also supply the needed nutrients for onions.

Different onion cultivars will produce different sized onions. Read the seed catalogs. The big one I'm familiar with is the Ailsa Craig. Under ideal conditions they will grow as big as a grapefruit. For best results, start them indoors under lights in January and transplant them outside in spring. In addition to what others have told you, do be careful to leave enough space between each one to allow for ultimate size!
