Grow Unlimited Supply of Onions in Big Plastic Bottles at Home
Growing multiple onions in a big plastic bottle with holes on the sides can be an interesting and space-saving way to cultivate these vegetables. Here’s a step-by-step guide on how to do it:
- A large plastic bottle (such as a 5-liter water bottle)
- Onions set or onion bulbs
- Potting mix or well-draining soil
- Scissors or utility knife
Take a clean, empty plastic bottle and remove any labels or stickers. Make sure the bottle is dry and free from any residue. You can use a 5-liter soda bottle or any large plastic container, depending on the number of onions you want to grow.
Carefully cut several small holes on the sides of the plastic bottle using a pair of scissors or a sharp knife. The number of holes will depend on how many onions you want to grow. These holes will serve as planting spaces for the onions.
Fill the plastic bottle with potting mix or well-draining soil up to the first row of holes. Ensure the soil is loose and well-aerated to promote good root growth.
Take onion sets or onion bulbs and gently place them through the holes on the sides of the bottle. Position each onion bulb with the roots facing downward into the soil and the green shoots facing outward.
Add more soil to the bottle, covering the first row of onions. Create a second row of holes slightly above the first row, and repeat the planting process by inserting onion bulbs through these new holes. Continue this process until you’ve planted all the desired onions.
Water the soil thoroughly to ensure that it is evenly moist. Make sure the water reaches all the onion bulbs and settles the soil around the roots.
Place the plastic bottle in a sunny location where the onions will receive at least 6-8 hours of sunlight daily. Water the onions regularly to keep the soil consistently moist but not waterlogged. Onions prefer well-draining soil, so avoid overwatering.
As the onions grow, you can carefully remove them from the holes once they reach a suitable size for consumption. You can harvest the onions gradually as needed, allowing the remaining onions to continue growing.
Maturing Time: Onions generally take around 100 to 175 days to reach maturity when grown from seeds and around 70 to 100 days when grown from sets or small bulbs. However, growing onions in a plastic bottle might lengthen this time frame due to potential limitations in space and nutrients compared to traditional soil gardening.
Note: This method of growing in a plastic bottle might not be the most ideal for fully mature onions due to the space and nutrient constraints, but it could work as a fun experiment or a way to grow green onions, which can be harvested much sooner (often in 3-4 weeks).

Quick Important Tips
- If the weather is too cold or frost is expected, bring the bottle indoors or cover the onions with a protective cloth or plastic.
- Ensure good air circulation to prevent mold or fungal issues.
Growing onions in a plastic bottle with holes on the sides is an innovative way to maximize space and grow fresh produce, even in limited areas like a small apartment or a studio. It’s also a great gardening project, especially for those with limited outdoor space or apartment balconies. With proper care, you can enjoy a bountiful harvest of homegrown onions from your plastic bottle garden!
