Onion sets look similar to miniature dried onion bulbs. Onion sets can be planted in rich, loose soil at least 4 inches deep and 4 to 6 inches apart to give the bulbs room to grow.

Transplanting Onion

Transplanting onions is the commonest and most preferred choice of growing onions. Onion transplants look like small green onions about the size of a pencil.

To transplant your onion-sprouted plant, you should sow in rich, loose soil at least 3/4″ – 1″ deep and 4″ apart to allow for bulb development. If not planted right away, store it in a cool, dry place.

They can tolerate drying out for a week or two and will sprout again. Before planting, avoid getting the bulbs wet.

After planting, water thoroughly but don’t overwater as this can cause the roots to rot and die off.

Step 6: Onion Management

You must maintain your onion farm. Routinely carry out the following task to allow your onions to grow

Weeding

Onions are delicate plants with a delicate root structure that is easily injured or harmed by weeds and twirling. Instead of plucking weeds, use a hoe to remove the tops of those that appear; pulling the weeds may pull out the onions’ roots, making growing difficult.

Regular Watering

You should also water your onions once a week with about 1 inch (2.5 cm) of water and supplement with a nitrogen fertilizer once a month for nutrition.

Mulching

To keep moisture in and weeds out, apply a thin layer of mulch between each plant immediately after planting.

Onions are massive feeders that require a steady supply of nitrogen for healthy leaf growth.

Fertilizer Application

You must incorporate a balanced fertilizer or high-quality compost into the soil before planting. Fertilize onions every two to three weeks after planting with a high-nitrogen fertilizer such as blood meal (organic), neem seed meal (organic), or ammonium sulfate.

When the onion begins to the bulb, stop fertilizing. This is from late April to early June in our area, depending on the day length of your onion.

Step 7: Harvesting

When the necks of onion bulbs soften, the leaves turn yellow, and the tops begin to fall over, it is the best sign that your onions are ready to harvest. Begin harvesting when one-quarter to one-third of the tops have fallen over in our region.

You should gently pull or lift the onions from the ground, and move the onions immediately to a sheltered area out of the sun with good airflow. This can be the final curing location or a temporary drying location.
