Growing method

This bunching onion produces long green leaves and a white shaft. The harvest targets the entire young plant, without waiting for the formation of a large storage bulb. Begin cultivation of "Bunching Onion" in an area prepared for sowing. To start cultivation: Depending on the crop and local season; sow in well-drained soil. Sowing depth: 1 cm (0.4 in). Recommended spacing: 3 to 5 cm (1.2 to 2 in) between plants; 35 to 38 cm (13.8 to 15 in) between rows. Emergence generally takes 12 to 14 days. Harvest the white shaft and leaves while they remain tender. These green onions are suitable for small, repeated harvests and are not managed like storage bulbs. At the beginning of the season, prepare the materials and check the condition of the soil before setting your schedule. Adapt interventions to the stage of the plants rather than a rigid date. After emergence, ensure sufficient light and space out the seedlings to avoid excessive competition. Gradually acclimate plants intended for the outdoors. During growth, observe the foliage, humidity, and the potential appearance of pests.
Soil and care

Soil and care

Soil & care

Soil pH

6.0 to 7.0 — general range recommended for the vegetable garden

Moisture

Regularly moist soil, with no standing water

Watering

Check moisture levels before watering and adjust the frequency according to rainfall, heat, and growth stage. Gently moisten the surface during germination to avoid displacing the seeds. Once the plants are established, direct water toward the soil rather than the leaves. Avoid standing water and extreme fluctuations between dryness and saturation. Containers generally dry out faster than garden beds and require more frequent checks.

Soil type

Use a soil or substrate that allows excess water to drain while retaining the moisture necessary for the roots. Work the soil when it is dry enough to avoid compaction. Remove weeds before planting and adapt the addition of organic matter to the crop. For containers, choose a potting mix appropriate for the plants being grown. A soil analysis is more useful than a systematic addition of amendments for determining the necessary corrections.

Fertilization

Base fertilization on soil fertility, the substrate used, and observed growth. Follow the dosages indicated on the chosen product; increasing applications does not guarantee better results. Pre-enriched potting soil does not require the same interventions as a poor substrate. Avoid placing concentrated fertilizer against seeds or fragile roots. Water according to the manufacturer's instructions and reduce applications when growth slows down.

Seasonal care

This bunching onion produces long green leaves and a white shaft. Harvesting targets the entire young plant, without waiting for the formation of a large storage bulb. At the start of the season, prepare your equipment and check soil conditions before setting your schedule. Adapt your actions to the plant stage rather than a rigid date. After emergence, ensure sufficient light and space out the seedlings to avoid excessive competition. Gradually acclimate plants intended for the outdoors. During growth, observe the foliage, moisture, and the possible appearance of pests. Identify the problem before choosing an intervention. Remove debris that hinders airflow, keep paths accessible, and re-evaluate watering after rainfall. Record sowing dates and key results. At the end of the cycle, clean your tools and store remaining packets in a cool, dry place. These observations allow you to adjust future sowings more precisely to your location. Prepare a fine seedbed, free of stones and large clods. Sow in place to allow the roots to develop without disturbance. Keep the surface layer moist during emergence, using a gentle spray that does not displace the seeds. Thin the young plants when necessary to reduce competition. Compacted soil or highly irregular watering can harm the quality of the harvest.
Growing in containers

Container growing

Container growing

Harvest the white shank and leaves while they remain tender. These green onions are suitable for small, repeated harvests and are not managed like storage bulbs. This bunching onion produces long green leaves and a white shank. The harvest is aimed at the whole young plant, without waiting for the formation of a large storage bulb. Place the container in its permanent location before filling it. Choose a stable pot with drainage holes that is large enough for root development; a simple closed cache-pot does not allow for water drainage. Use potting mix rather than compact garden soil. Moisten the substrate before sowing or planting, without saturating it. Leave a rim at the top to facilitate watering and keep space between the plants. Check moisture regularly with your finger, as the surface may dry out while the bottom remains damp. Water slowly until water runs out of the holes, then empty the saucer. During hot weather, check the pots more often. Fertilize according to the needs of the crop and the instructions on the chosen product. Roots have a limited volume: pot cultivation therefore requires different monitoring than open-ground cultivation. Position any necessary supports upon installation. Keep easy access to inspect the leaves, remove damaged parts, and harvest without pulling on the stems. At the end of the cycle, remove debris and clean the equipment before reuse.

Companion plants & uses

Companion plants

Organize neighboring crops according to their light requirements, height, and space occupied at maturity. Prevent tall plants from permanently shading smaller ones or blocking access for watering. Successive crops can use the same space if the first is harvested before the next one expands. Flowers diversify the garden, but companion planting does not guarantee the absence of pests. Keep enough air between plants and observe the interactions on-site. Use companion planting as an organizational tool, without attributing automatic protection against diseases to it.

Recipe and storage

Recipe idea

From garden to table

Shallot. For 4 servings, allow 500 g (18 oz) of vegetables, 1 small onion, 15 ml (1 tbsp) of oil, and 60 ml (¼ cup) of water. Prepare a side dish of cooked vegetables with herbs, choosing only the edible parts of the harvest. Wash the vegetables, remove any damaged parts, and cut them into pieces of uniform size. Heat a little oil in a saucepan, add a minced onion, and let it soften over medium heat. Incorporate the firmer vegetables first, then a small amount of water to prevent them from sticking. Cover and continue cooking until they become tender. Add delicate leaves or pieces that cook quickly toward the end. Season with fresh herbs, pepper, and a little salt to taste. Serve with rice, bread, or another cooked grain. Adjust the cooking time based on the vegetable used: the desired textures vary depending on the harvest. Refrigerate leftovers promptly in a clean container. This preparation is intended to be consumed as a cooked meal; it is not a canning method.
