  • Resource competition in raised beds or small gardens can be acute.

Peas

The chemistry between peas and Long Green Onion is like mixing oil and water. Peas, similar to beans, find the soil environment around onions less than ideal, leading to stunted growth and a less bountiful pea crop.

  • Growth patterns of peas can be disrupted by nearby Long Green Onions.
  • Nutrient competition is a concern, making peas a less-than-ideal companion.

    • Utilize vertical space by growing tomatoes near your onions, allowing the taller tomato plants to provide a bit of shade.
  • Spacing Considerations:

    • Give each Long Green Onion plant about 2-3 inches of space to ensure adequate air circulation.
    • Carrots and lettuce can be planted closely, as they don't have a large spread.
    • For tomatoes, leave about 18-24 inches between plants to accommodate their wider growth.
