The Ideal Time of the Year to Cultivate Onions

Onions (Allium cepa) are resilient plants that can grow nearly year-round despite the temperature.

The day length for bulbing is the most crucial factor to consider, as onions require a specific number of daylight hours during the growing season.

The onions are divided into 3 categories depending on the daylight hours received. Hence, they are separated into short-day onions, long-day onions, and intermediate-day onions.

Onions need full, direct sunshine to grow and indicate the beginning of the bulbing process.

In the warmest of temperatures, onions may experience sunscald when exposed to direct sunlight.

Onions should be placed between 6 to 8 inches apart if they are grown for bulbing. With a smaller gap, a large reduction in bulb size can be achieved.

Because onions have shallow roots and a high food requirement, fertilizing is necessary.

Your onion crop will be successful once you determine the timing and the appropriate variety of onions for your latitude.
