How big do red candy onions get?

The size of Red Candy onions can vary depending on various factors such as growing conditions and the length of the growing season. Generally, Red Candy onions are known for their flattened, globe-shaped bulbs that can grow to about 4 inches in diameter. This size is considered quite large for an onion and is especially impressive considering the mild flavor and beautiful red-ringed interior that the Red Candy onion possesses.

When I first started growing Red Candy onions in my garden, I was amazed at the size they reached. The bulbs were solid and substantial, making them an excellent choice for fresh eating. I found that the larger bulbs were not only visually appealing but also provided a generous amount of onion flesh for cooking and slicing.

One of the reasons why Red Candy onions can grow quite large is because they have a long growing season. Onions, in general, are known for their ability to tolerate cooler temperatures, and Red Candy onions are no exception. They can be planted in early spring or late summer to take advantage of the cooler weather and longer growing period.

In addition to the growing season, the soil conditions and care provided to the onions can also influence their size. Red Candy onions prefer well-drained soil that is rich in organic matter. Prior to planting, it is beneficial to amend the soil with compost or well-rotted manure to improve its fertility. This will provide the onions with the necessary nutrients to grow to their full potential.

Proper spacing is also crucial for the development of large bulbs. Red Candy onions should be planted about 4-6 inches apart to allow sufficient room for bulb formation. Crowded onions may not have enough space to grow, resulting in smaller bulbs.

Regular watering is essential during the growing season to ensure the onions have adequate moisture for growth. However, it is important to avoid overwatering, as this can lead to rot and smaller bulb sizes. A consistent and even moisture supply will help the onions develop uniformly and reach their full size.

As the onions mature, it is important to keep an eye on them and harvest them at the right time. Red Candy onions should be harvested when the tops have fallen over and started to dry out. This indicates that the onions have reached their full size and are ready for harvesting. Care should be taken during the harvesting process to avoid damaging the bulbs, as any injuries can impact their storage potential.

Red Candy onions have the potential to grow to a size of about 4 inches in diameter. Their flattened, globe-shaped bulbs are visually appealing and provide a mild flavor that makes them great for fresh eating. By providing the onions with the right growing conditions, including a long growing season, well-drained soil, proper spacing, and adequate moisture, you can encourage them to reach their full size and enjoy their impressive harvest.
