How to grow onions and garlic in an old styrofoam box: very easy

Growing onions and garlic in an old Styrofoam box is an excellent way to recycle and engage in sustainable gardening. This method is not only cost-effective but also space-saving, making it ideal for urban gardeners or those with limited outdoor space. Here’s a simple guide on how to cultivate these flavorful and essential kitchen staples using a repurposed Styrofoam box.

Materials Needed:

  • An old Styrofoam box
  • Drill or sharp object for making drainage holes
  • Potting soil
  • Compost or well-rotted manure
  • Onion sets or garlic cloves
  • Watering can
  • Optional: Mulch (e.g., straw, grass clippings)

Step-by-Step Guide:

Step 1: Prepare the Styrofoam Box

Ensure your Styrofoam box is clean and free from any residues or contaminants. Using a drill or a sharp object, create several drainage holes at the bottom of the box to prevent waterlogging, which is detrimental to onion and garlic growth.

Step 2: Fill with Soil

Mix potting soil with compost or well-rotted manure to enrich the soil, which will provide essential nutrients for your plants. Fill the Styrofoam box with this mixture, leaving about an inch of space at the top.

Step 3: Plant Onion Sets or Garlic Cloves

For onions, plant the sets (small bulbs) with the pointy end up, burying them about an inch deep into the soil and spacing them about 4-6 inches apart. For garlic, plant the cloves pointy end up, about 2 inches deep and 4 inches apart. Ensure each clove is buried well with just the tip peeking above the soil surface.

Step 4: Watering

After planting, water the soil thoroughly to settle it around the bulbs. Keep the soil moist but not waterlogged, as onions and garlic both dislike too much water.

Step 5: Location

Place the Styrofoam box in a location that receives at least 6 hours of direct sunlight per day. Both onions and garlic need plenty of light to grow well.

Step 6: Care and Maintenance

As the onions and garlic grow, keep the area weed-free and consider adding a layer of mulch to retain moisture and suppress weeds. Water regularly, especially during dry spells, but ensure the soil drains well and does not become soggy.

Step 7: Harvesting

Onions are ready for harvest when their tops begin to fall over and turn yellow. Gently pull them out of the soil and allow them to dry in the sun for a few days. For garlic, harvest when several of the lower leaves go brown, but five or six upper leaves remain green. Carefully dig them up and let them cure in an airy, shaded spot for two weeks.

Additional Tips:

  • Rotate your crops each year to prevent disease buildup and ensure soil fertility.
  • Be vigilant about pests and diseases; onions and garlic can attract onion flies and are susceptible to fungal infections.

By following these steps, you’ll be able to grow your own onions and garlic right in an old Styrofoam box. This method not only recycles materials but also provides you with fresh, organic produce right at your doorstep.
