Overview of Kelsae Giant Onion
The Kelsae Giant Onion cultivar is well-known for its impressive size and sweet, mild flavor. Developed by Scottish horticulturist George Starr in the 1950s, this onion can grow up to 15 pounds (6.8 kg) and measure up to 15 inches (38 cm) in diameter.
The Kelsae Giant Onion is a long-day onion, requiring about 14-16 hours of daylight to produce a bulb. It is typically grown as an annual plant in colder climates but can also be developed as a biennial in warmer areas.
This onion has pale yellow skin and white flesh and is often used for cooking and in salads. It is vital for its mild flavor and ability to be sliced into large rings. The Kelsae Giant Onion is also well-suited for storage, with its bulbs able to last for several months if stored properly.

Benefits of The Kelsae

They are also thought to reduce high blood pressure and protect against blood clots because of their potent anti-inflammatory properties.
How to sow and care for The Kelsae
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 or multiple rows per bed.
The Kelsae 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 weekly water from rainfall or irrigation. 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.
