Growing onions from bulbs is a cost-effective way to enjoy fresh onions all year round. Here’s a step-by-step guide to help you grow onions without spending much money:

Materials Needed:

  1. Onion Bulbs: Purchase onion bulbs from a local nursery or garden center, or use onion sets (small, dormant onions).
  2. Garden Space or Containers: Choose a well-draining garden bed or large containers with at least 6 inches of soil depth.
  3. Compost or Well-Rotted Manure: Enrich the soil with organic matter to provide essential nutrients.
  4. Mulch (Optional): Mulching helps retain soil moisture and suppresses weeds.
  5. Watering Can or Hose: Regular watering is crucial for onion growth.


  1. Selecting Onion Bulbs:
    • Choose onion bulbs that are firm, dry, and free from mold or signs of decay. Look for varieties suitable for your region.
  2. Preparing the Soil:
    • Onions prefer well-draining, loose soil. Amend the soil with compost or well-rotted manure to improve fertility. Remove any rocks or debris.
  3. Planting Onion Bulbs:
    • Plant the onion bulbs about 1 to 2 inches deep with the pointed side facing upward. Space the bulbs according to the variety, typically 4 to 6 inches apart.
  4. Watering:
    • Water the onion bulbs thoroughly after planting. Keep the soil consistently moist, especially during dry periods. Onions need regular watering for optimal growth.
  5. Fertilizing (Optional):
    • Onions are light feeders, but you can side-dress with a balanced fertilizer once they start growing. Follow the package instructions for application rates.
  6. Mulching (Optional):
    • Apply a layer of mulch around the onions to help retain soil moisture and suppress weeds. Mulching also helps regulate soil temperature.
  7. Thin Out if Necessary:
    • If the onion bulbs are planted too close together, thin them out once they are a few inches tall. This ensures proper spacing for bulb development.
  8. Weeding:
    • Keep the area around the onions weed-free. Weeds compete for nutrients and moisture, which can affect onion growth.
  9. Harvesting Green Onions:
    • You can start harvesting green onions when they reach the desired size. Pull them gently from the soil, leaving the remaining onions to continue growing.
  10. Harvesting Mature Onions:
    • Allow the majority of the onions to grow until the tops start to yellow and fall over. Once this happens, carefully lift the mature onions from the soil and let them cure in a dry, well-ventilated area for a couple of weeks.
  11. Storing Onions:
    • After curing, trim the tops and store the onions in a cool, dry place. Properly stored onions can last for several months, allowing you to enjoy them throughout the year.

By following these steps, you can grow onions from bulbs and have a steady supply of fresh onions without spending much money. Adjust the guidelines based on your local climate and soil conditions. Happy gardening!
