FAQs

When is the best time to sow Onion Hylander seeds?

You can sow Onion Hylander seeds directly outdoors in spring, from February onwards. Alternatively, you can start them indoors in modules from late winter.

How far apart should I space the onion plants?

For medium-sized bulbs, thin seedlings to 10cm (4") apart. If you desire larger bulbs, you can use a slightly wider spacing.

How long does it take for the onions to mature?

Onion Hylander can be harvested from July through until September, depending on when they were sown and growing conditions.

Can I grow these onions in containers?

Yes, provided the container is deep enough and the soil is well-drained. Ensure the container receives full sun.

What makes this variety 'F1 Hybrid'?

F1 Hybrid refers to the first generation offspring of a cross between two distinct parent lines. This often results in improved characteristics like disease resistance, vigor, and uniformity.

How do I know if my soil is well-drained enough?

Well-drained soil allows water to pass through easily. You can test this by digging a hole, filling it with water, and seeing how quickly it drains. If it takes more than a few hours, drainage may be an issue. Incorporating compost helps improve drainage.

What is the expected yield per packet?

Each packet contains approximately 125 seeds. The final number of usable onions will depend on germination rates, thinning, and growing conditions.

Troubleshooting

Seedlings are leggy and weak

Ensure seedlings are receiving adequate light after germination. If grown indoors, provide a sunny windowsill or grow light. Thinning overcrowded seedlings will also help stronger ones develop.

Onion bulbs are not developing

Check for adequate sunlight and ensure soil is well-drained. Overcrowding can also hinder bulb formation; ensure proper thinning has occurred.

Plants are attacked by birds or insects

Cover seedlings and young plants with protective netting or fleece. Ensure plants are watered consistently, as stressed plants are more susceptible.

Poor germination rate

Ensure seeds are stored correctly in a cool, dry place. Check sowing depth (1cm/0.5") and maintain appropriate germination temperatures (10-15°C / 50-59°F).

Pros and Cons

Setup, Compatibility & Care

Sowing Outdoors:

  1. Prepare planting area several weeks in advance by incorporating well-rotted garden compost.
  2. Direct sow seeds outdoors in spring on firm, well-drained soil in full sun.
  3. Sow thinly at a depth of 1cm (1/2") and space rows 30cm (12") apart.
  4. Once seedlings are large enough to handle, thin them to 10cm (4") apart for medium bulbs, or wider for larger ones.

Sowing Indoors:

  1. Sow seeds indoors in module trays using free-draining seed sowing compost at a depth of 1cm (1/2").
  2. Place in a propagator or seal container within a plastic bag at 10-15°C (50-59°F) until germination (10-14 days).
  3. Once germinated, grow seedlings on in cool conditions until all risk of frost has passed.
  4. Plant outdoors spacing them 10cm (4") apart.

Care:

  • Soil: Prefers well-drained soil. Avoid planting on freshly manured ground. Raised beds are recommended for very wet areas.
  • Watering: Water thoroughly after planting and during dry spells.
  • Protection: Cover with protective netting or fleece to prevent birds and insects from damaging the plants.
  • Sunlight: Requires full sun for optimal growth.
  • Established Size: Plants grow up to 45cm (18in) tall with a spread of up to 15cm (6in).
  • Compatibility: Suitable for kitchen gardens and general vegetable patches.
