How to sow and care for Giant Onion Seeds
Sow giant onion seeds in flats in mid-February. It is best to plant the seeds thickly and then thin them to a half-inch spacing. When the plants reach five inches in height, they should be trimmed. Make sure the soil is loose and allows for good drainage. It is best to use sandy soil. A raised bed is ideal. Compacted, hard soil will prevent the bulb from growing. In addition to peat moss, compost, or other organic matter, add about an inch and a half. By testing your soil, you can determine the type of fertilizer you need to use. It requires a lot of space. Bulbs that are too close together will not grow properly. Plants should be spaced 4 to 6 inches apart in rows 12 to 18 inches apart. The little plants can be planted in two rows or multiple rows per bed.
The giant onion needs full sun to grow the best. They can tolerate light frost if planted outside in late April. They can tolerate light frost if planted outside in late April. As they have giant bulbs, they need irrigation. The roots of onions are shallow, so they are susceptible to drought. The plant should receive one inch of water per week from rainfall or irrigation. In order for the bulb to grow properly, water must be readily available. Many gardeners water the bulb every week during this stage. You have to control weeds because they compete for water, nutrients, and sunlight.
