How to Grow Evergreen Bunching Onion
Overview
Evergreen Bunching Onions, scientifically known as Allium fistulosum, are a type of perennial scallion that offer a reliable harvest all season long without forming bulbs. These nearly foolproof plants regrow after being cut, making them an excellent choice for home gardeners looking to add fresh, flavorful onions to their meals throughout the growing period.
Growing Conditions
Evergreen Bunching Onions thrive in full sun and well-draining soil with a pH between 6.0 and 7.5. They prefer cool temperatures and can tolerate some shade in hotter climates. These onions are not frost-tolerant, so they should be planted in the spring once the threat of frost has passed.
Planting & Care
Sow Evergreen Bunching Onion seeds directly into the ground in early spring, about 1/4 inch deep and 1 inch apart. Thin the seedlings to a final spacing of 3-4 inches when they reach 3-4 inches tall. Keep the soil consistently moist during germination and maintenance. Fertilize lightly if needed, but avoid over-fertilizing as it can cause the plants to bulb and stop growing.
Common Problems
Evergreen Bunching Onions are generally low-maintenance and resistant to most common garden pests. However, they may fall prey to onion flies or slugs in some cases. To prevent these issues, use organic methods like neem oil or hand-picking for insect control, and consider using barriers or traps for slug prevention.
Harvest or Enjoy
Start harvesting your Evergreen Bunching Onions once they reach a scallion size, typically 4-6 weeks after planting. Simply snip off the green tops as needed, taking no more than one-third of the leaf growth at a time. The onions will quickly regrow from the basal plate at the soil level, providing a steady supply throughout the season.
