DIY: Never Buy Green Onions Again! Growing Them in a Plastic Bottle
Hey everyone! Are you tired of buying green onions only to use a few and watch the rest wilt away in your fridge? I know I was! That’s why I decided to try this super easy and rewarding DIY project: growing green onions from a plastic bottle. It’s a fantastic way to recycle, save money, and always have fresh green onions on hand. Plus, it’s surprisingly simple!
Here’s what you’ll need:
* An empty plastic bottle (2-liter soda bottles work great!)
* A sharp knife or scissors
* Potting soil
* Green onion scraps (the white bulb ends with roots attached)
* Water
* A sunny spot
Preparing the Plastic Bottle Planter
Okay, let’s get started by prepping our plastic bottle. This is where we’ll create the perfect little home for our green onions.
1. Clean the Bottle: First things first, make sure your plastic bottle is clean. Rinse it out thoroughly with soap and water to remove any residue. This will help prevent mold or bacteria from growing later on.
2. Cut the Bottle: Now, grab your knife or scissors. We’re going to cut the bottle horizontally. You have two options here:
* Option 1 (Single Planter): Cut the bottle about 4-5 inches from the bottom. You’ll be using the bottom portion as your planter. Discard the top part (or save it for another project!).
* Option 2 (Stacked Planter): Cut the bottle in half. Then, cut the top half again, about 2-3 inches from the bottle cap. Invert the top portion (the part with the bottle cap) into the bottom half. This creates a self-watering system! The bottle cap should be removed to allow water to wick up into the soil. I personally prefer this method because it requires less watering.
3. Drainage Holes (If Needed): If you’re using the single planter method (Option 1), you’ll need to create drainage holes. Carefully poke 4-5 small holes in the bottom of the bottle. This will prevent the soil from becoming waterlogged, which can rot your green onions. If you’re using the stacked planter (Option 2), you don’t need drainage holes in the bottom half, as the water will be contained in the reservoir.
Planting the Green Onion Scraps
Alright, our planter is ready! Now comes the fun part: planting those green onion scraps.
1. Fill with Soil: Fill your plastic bottle planter with potting soil, leaving about an inch of space at the top. Don’t pack the soil too tightly; you want it to be loose and airy so the roots can breathe.
2. Prepare the Green Onion Scraps: Take your green onion scraps (the white bulb ends with the roots). Make sure the roots are still attached. If the roots are very long, you can trim them slightly, but don’t cut them off completely.
3. Plant the Scraps: Now, gently push the green onion scraps into the soil, root-end down. Space them about an inch or two apart. You want the white part of the bulb to be buried in the soil, but the green part should be sticking out.
4. Water Thoroughly: Once all the scraps are planted, water the soil thoroughly. Make sure the water drains out of the drainage holes (if you have them). If you’re using the stacked planter, pour water into the bottom half until it reaches just below the soil level in the top half.
Caring for Your Green Onions
Now that your green onions are planted, it’s time to give them some TLC!
1. Find a Sunny Spot: Green onions need plenty of sunlight to thrive. Place your plastic bottle planter in a sunny spot, like a windowsill or balcony. Aim for at least 6 hours of sunlight per day.
2. Water Regularly: Keep the soil consistently moist, but not soggy. Water when the top inch of soil feels dry to the touch. If you’re using the stacked planter, check the water level in the bottom half regularly and refill as needed.
3. Fertilize (Optional): While not essential, fertilizing your green onions can help them grow faster and stronger. You can use a diluted liquid fertilizer every few weeks. Follow the instructions on the fertilizer packaging.
4. Harvesting: The best part! You can start harvesting your green onions as soon as they’re a few inches tall. Simply snip off the green tops with scissors, leaving about an inch or two of the green part intact. The green onions will continue to grow back, so you can harvest them multiple times.
Troubleshooting
Sometimes, things don’t go exactly as planned. Here are a few common issues you might encounter and how to fix them:
* Yellowing Leaves: Yellowing leaves can be a sign of overwatering or underwatering. Check the soil moisture and adjust your watering accordingly. It could also indicate a lack of nutrients, so try fertilizing.
* Slow Growth: Slow growth can be caused by insufficient sunlight or poor soil. Make sure your green onions are getting enough sunlight and that the soil is well-draining.
* Rotting Bulbs: Rotting bulbs are usually a sign of overwatering. Make sure your planter has adequate drainage and that you’re not watering too frequently.
Advanced Tips and Tricks
Want to take your green onion growing to the next level? Here are a few extra tips and tricks:
* Succession Planting: To ensure a continuous supply of green onions, plant new scraps every few weeks. This way, you’ll always have some ready to harvest.
* Different Varieties: Experiment with different varieties of green onions. Some varieties are milder, while others are more pungent.
* Indoor vs. Outdoor: Green onions can be grown indoors or outdoors, depending on your climate. If you live in a cold climate, you’ll need to bring your planter indoors during the winter months.
* Companion Planting: Green onions are great companion plants for many vegetables, such as tomatoes, peppers, and carrots. They can help repel pests and improve the flavor of your vegetables.
* Using Other Containers: While plastic bottles are a great option for recycling, you can also use other containers, such as yogurt cups, tin cans, or even old shoes! Just make sure the container has drainage holes.
* Hydroponics: For a more advanced project, you can try growing green onions hydroponically. This involves growing them in water without soil. There are many tutorials online that can guide you through the process.
* Saving Seeds: If you let your green onions flower, they will produce seeds. You can collect these seeds and use them to grow new green onions. However, keep in mind that the seeds may not produce plants that are identical to the parent plant.
* Pest Control: Green onions are generally pest-resistant, but they can sometimes be attacked by aphids or other small insects. If you notice any pests, you can try spraying them with insecticidal soap or neem oil.
* Soil Amendments: Adding compost or other organic matter to the soil can improve its fertility and drainage. This will help your green onions grow stronger and healthier.
* Rotating Crops: If you’re growing green onions in the same container year after year, it’s a good idea to rotate the soil. This will help prevent the buildup of pests and diseases.
I hope you found this guide helpful! Growing green onions from plastic bottles is a fun, easy, and rewarding project that anyone can do.
