At A Glance


Onions can be good companions for many garden plants, as they may deter certain pests. Avoid planting onions near beans and peas. Plant in a location with full sunlight exposure for at least 6-8 hours a day.


Onions prefer well-draining, fertile soil with a slightly acidic to neutral pH. Work in compost or well-rotted manure for improved fertility.


Expert Tip

Centurion Onions: Planting and Care Guide

Planting Time:

  • Plant Centurion Onion sets or seeds in early spring, as soon as the soil can be worked. Onions can also be planted in the fall for overwintering in milder climates.

Bulb Characteristics:

  • Centurion Onions are known for producing medium-sized, round bulbs with a mild and sweet flavour.

Growing Season:

  • Onions have a growing season that typically spans from spring to late summer, with harvest occurring when the tops begin to yellow and fall over.


  • Onions prefer well-draining, fertile soil with a slightly acidic to neutral pH. Work in compost or well-rotted manure for improved fertility.

Sunlight Requirements:

  • Plant in a location with full sunlight exposure for at least 6-8 hours a day.


  • Provide consistent moisture, especially during dry spells. Onions prefer evenly moist soil.


  • Fertilize with a balanced, all-purpose fertilizer at planting and then side-dress with nitrogen when the tops are actively growing.


  • Mulch around the onion plants to conserve soil moisture, suppress weeds, and regulate soil temperature.


  • Thin seedlings to ensure proper spacing, allowing bulbs to develop without competition.


  • Harvest onions when the tops have fallen over and started to dry. Cure them in a well-ventilated, shaded area for a few weeks before storage.


  • Store cured onions in a cool, dry place with good air circulation. Braiding or placing onions in mesh bags are common storage methods.

Companion Planting:

  • Onions can be good companions for many garden plants, as they may deter certain pests. Avoid planting onions near beans and peas.

Pest and Disease Control:

  • Keep an eye out for onion pests, such as onion thrips and onion maggots. Practice crop rotation to minimize disease issues.

Expert Tip:

  • Consider interplanting onions with other vegetables and herbs to maximize space utilization and provide mutual benefits in terms of pest management.
