Prepare a sunny garden spot as soon as the ground can be worked in spring. Spade the soil to a depth of 10 to 12 inches. Rake out rocks and clods.
Fertilize the planting space, using a balanced fertilizer with a ratio such as 10-10-10 or 20-20-20. Use approximately 1/2 to 3 pounds of dry fertilizer for every 100 square feet of planting space.
Create shallow rows, using the tip of a hoe. Space the rows 12 to 18 inches apart.
Plant Ebenezer onion seeds in the rows 1/2 inch deep, or plant sets 1 to 2 inches deep. Allow 3 inches between each seed or set.
Water the onions immediately after planting, and then keep the soil moist until the young plants are established and showing healthy new growth.
Decrease frequency of watering when the small plants are established. Water deeply only once every seven to 10 days, saturating the soil to a depth of 6 to 8 inches. Don't allow the soil to become bone dry, as dry soil results in stunted growth. However, avoid frequent, light waterings and never allow the soil to remain soggy.
Pull small, green Ebenezer onions as soon as the onions reach an edible size -- about the size of a marble. Pull every other onion in the row to allow space if you want to allow larger onions to develop for winter storage.
Harvest onions for winter storage when the tops fall over naturally in mid to late summer.
