Understanding Evergreen Bunching Onions
Evergreen Bunching Onions, a variety of onions that stay green all year, have long, slender, hollow green tops. Known for their mild flavor, they're versatile in cooking and also known as scallions or spring onions.
Many cuisines consider them a staple due to their subtle flavor and succulent texture. These onions are perfect for salads when used raw, stir-fries when sautéed, or grilled as a side dish.
The First Step
Choose your seeds wisely from a reputable supplier, ensuring they are fresh. Older seeds might yield a lower germination rate. Handle them with care to prevent damage.
Some growers advise soaking seeds in warm water for several hours before planting. This method might expedite germination by softening the seed coat, allowing the seedling to break through with ease.
Ideal Soil and Planting Conditions
Choose well-draining, either sandy or loamy, soil with a pH varying between 6.0 to 7.5.
Generally, they should be buried roughly 1/4 inch deep. This provides ample protection against external elements while also allowing for easy emergence. In terms of plant spacing, leaving 4 to 5 inches between each plant is recommended.
Care and Maintenance Tips
Generally, a thorough watering once a week should suffice. During hot, dry weather, watering every second to third day might be required.
Although pests don't commonly affect their growth, always remain vigilant. Check routinely for signs of damage or disease, and act promptly if required.
Applying a balanced, slow-release fertilizer every six weeks can contribute to maintaining healthy growth.
Harvesting and Storing Your Crop
To guarantee a successful harvest, proper curing is essential. During this process, harvested onions undergo a drying period for several days.
Dry, cool, well-ventilated spaces make the best storage areas. Some gardeners suggest using mesh bags or pantyhose for storage, promoting optimal air circulation.

FAQ: Evergreen Bunching Onions – Expert Growing Guide from Bloom Ranch of Acton
1. What are evergreen bunching onions, and how are they different from bulb onions?
Evergreen bunching onions are non-bulbing, perennial onions prized for their slender, scallion-like stalks and mild flavor. Unlike bulb onions, they grow in clusters and can be harvested multiple times from the same plant.
2. When is the best time to plant evergreen bunching onion seeds?
For most regions, the best time is early spring or late summer. In mild climates like Acton, California, you can sow seeds nearly year-round, ideally in well-drained soil once the risk of frost has passed.
3. Do I need to start bunching onion seeds indoors, or can I sow them directly outside?
You can do either. Direct sowing works well in warmer climates, while starting indoors 6–8 weeks before the last frost helps establish stronger seedlings in cooler zones.
4. What type of soil is best for growing evergreen bunching onions?
They thrive in loamy, well-draining soil with a neutral pH (6.0–7.0). Bloom Ranch recommends amending with compost or aged manure to enhance fertility and structure.
5. How deep and far apart should I plant the seeds?
Sow seeds ¼ inch deep and about ½ inch apart. Once seedlings are established, thin them to 1–2 inches apart to allow proper air circulation and steady growth.
6. How often should I water evergreen bunching onions?
Keep the soil consistently moist but not soggy. Water 1–2 inches per week, increasing frequency in hot, dry weather. Mulching helps retain moisture and suppress weeds.
7. Do bunching onions need fertilizer?
Yes. Start with a balanced, slow-release fertilizer at planting, then follow up with a nitrogen-rich feed every few weeks to encourage lush, green tops.
8. How long do evergreen bunching onions take to mature?
You can start harvesting young onions as early as 60 days, but full-size bunching typically takes 75–90 days from seed. They’re great for cut-and-come-again harvesting.
9. Can I grow bunching onions in containers or raised beds?
Absolutely. Bloom Ranch growers suggest using containers at least 6–8 inches deep with good drainage. They perform well in raised beds due to improved soil control and airflow.
10. How do I harvest evergreen bunching onions without killing the plant?
Use scissors or a sharp knife to cut stalks about 1 inch above the soil line. This allows the base to regrow for multiple harvests throughout the season.
11. Are bunching onions perennial or annual?
They are perennial in USDA zones 5–9 and can overwinter with mulch. In colder climates, treat them as annuals or overwinter indoors to restart in spring.
12. What pests or diseases should I be aware of?
Common issues include onion maggots, thrips, and downy mildew. Rotate crops, use insect netting, and apply neem oil or natural fungicides as needed. Healthy soil and spacing reduce risk significantly.
