- Empty 2-litre plastic bottle (clear)

Step-by-Step Guide to Canada’s Onion Bottle Gardening Hack
- Step 1: Prepare the Bottle
Cut the top portion of the bottle to create an opening for adding soil. Use a knife or scissors carefully and make small holes around the sides for onion shoots. These holes allow bulbs to sprout outward and grow bigger.
- Step 2: Add Soil Layer
Fill the bottom of the bottle with a layer of potting soil. Press it gently to remove air gaps. Ensure the soil remains slightly moist, not too wet, as onions dislike soggy conditions.
- Step 3: Insert Onion Bulbs
Place small onion bulbs into the side holes with the tips facing outward. Continue adding soil and more bulbs in layers until the bottle is filled. Each bulb will sprout leaves through its hole, creating a green tower of onions.
- Step 4: Water and Place Properly
Water the soil evenly using a spray bottle. Keep the bottle in a sunny location such as a balcony or near a window. Onions need at least 5–6 hours of sunlight daily for healthy growth.
- Step 5: Maintain Growth
Every few days, check moisture levels and rotate the bottle to ensure even sunlight exposure. Trim any weak shoots to let strong ones flourish. Within a few weeks, you’ll notice steady growth and thickening bulbs.
- Step 6: Harvest the Onions
Once the tops begin to yellow and fall over, your onions are ready to harvest. Gently remove them from the bottle, dry them in shade for a few days, and store them in a cool, dry place.
Benefits of the Bottle Onion Growing Method
