Onion 'Sturon' Planting & Care Guide

Onion 'Sturon' is a popular and reliable variety known for its excellent storage qualities and consistent yields. This hardy, disease-resistant variety produces medium to large golden-brown bulbs with a firm texture and mild flavour, making it perfect for cooking, salads, and long-term storage.

Grown from sets (immature onion bulbs) rather than seeds, Onion 'Sturon' is easy to cultivate, making it a favourite among both beginner and experienced gardeners. It thrives in well-drained soil and requires minimal maintenance.

• Spread: Reaches approximately 15-20cm (6-8 inches) wide
• Bulb Size: Medium to large, golden-brown with firm white flesh
• Harvest Time: Mid to late summer (July - August)
• Storage: Excellent – can be stored for months

How to Plant Onion 'Sturon'

Choosing the Right Location

• Prefers a sunny position with at least 6 hours of direct sunlight per day.
• Requires well-drained, fertile soil for the best results.
• Avoid areas where onions or related crops (garlic, leeks) were grown in the past year to reduce disease risk.

Soil Preparation

• Best pH: Slightly acidic to neutral (pH 6.0 - 7.0).
• Enrich the soil with organic compost or well-rotted manure a few weeks before planting.
• Ensure the soil is light and crumbly – heavy, compacted soil can lead to misshapen bulbs.

Planting Instructions

1. When to Plant:

   • Plant sets in early to mid-spring (March to April) when the soil is workable.

2. Spacing:

   • Plant onions 10-15cm (4-6 inches) apart in rows 30cm (12 inches) apart to allow airflow.

3. How to Plant:

   • Push each set gently into the soil, so just the tip is visible above the surface.
   • Do not plant too deep, as this can prevent proper bulb development.

4. Watering After Planting:

   • Water lightly to help establish roots but avoid waterlogging.

Maintenance Tips for Onion 'Sturon'

Watering & Feeding

• Keep soil moist but not waterlogged – onions dislike sitting in wet conditions.
• During dry periods, water once a week to encourage bulb formation.
• Avoid overwatering once bulbs start forming, as too much moisture can cause rot.
• Apply a high-potassium fertilizer (e.g., liquid seaweed feed) every 3-4 weeks to encourage strong growth.

Weeding & Mulching

• Regularly remove weeds, as onions do not compete well with them.
• Apply a thin layer of mulch (straw, grass clippings) around the plants to retain moisture and suppress weeds.

Pest & Disease Control

• Onion Fly: Use netting or fleece to protect young plants from onion fly infestations.
• Downy Mildew: Ensure good air circulation and avoid overhead watering to prevent fungal diseases.
• Root Rot: Avoid planting in waterlogged soil to prevent rot and fungal issues.

Harvesting & Storing

• When to Harvest:

  • Onions are ready to harvest when the foliage turns yellow and starts to flop over (usually July - August).
  • Lift bulbs carefully using a fork or trowel, avoiding damage.

• Drying & Storing:

  • Lay onions in a warm, dry, and well-ventilated area for two weeks to cure.
  • Once dried, store in mesh bags or wooden crates in a cool, dry place.
  • Well-cured 'Sturon' onions can be stored for several months without sprouting.
