How to Plant Red Onion Bulbs


Red onion bulbs will reward any gardener with delicious cooking onions during the last half of the summer. Plant red onion bulbs as early in the spring as possible, because onions prefer cool soil. Spring frosts will not damage onion bulbs. Make sure you give the onion bulbs plenty of space in the garden to allow them to grow to as large as possible.

Step 1

Prepare the growing area as early in the spring as possible. Work the soil with the garden spade down to a depth of approximately 6 inches. Add a 2-inch layer of compost to the top of the soil to improve the quality of the soil. Work the compost in with the garden spade. Rake the soil surface smooth to finish preparing the growing area.

Step 2

Select tiny red onion bulbs for best results. Onion bulbs smaller than a nickel will produce adequate onions.

Step 3

Dig holes for the red onion bulbs approximately 3 inches apart. Make the holes only deep enough to cover the bulbs with a thin layer of soil. Make rows 1 foot apart.

Step 4

Place the red onion bulbs into the prepared holes with the roots facing down. Cover the bulbs with soil and pat the soil firmly over the onions.

Step 5

Water the newly planted red onion bulbs generously after planting. Keep weeds away from the onions by pulling them by hand.
