Grow Onions Fast in Plastic Bottles – No More Grocery Trips!
Want an endless supply of onions without ever stepping foot in a store? Turn plastic bottles into mini onion farms! It’s simple, sustainable, and surprisingly fun. Here’s your easy guide to growing onions quickly for fast harvesting:
What You’ll Need:
1. Plastic Bottles
Grab a few large, empty plastic bottles (2 liters or more). Cut off the top and poke drainage holes in the bottom. You can even cut side holes along the bottle to grow more onions vertically!
2. Onion Sets or Sprouting Bulbs
For a speedy harvest, skip seeds—go with onion sets or sprouted bulbs from your kitchen. They grow faster and need less care.
3. Quality Potting Mix
Fill your bottle with loose, well-draining soil. Mix in compost or organic scraps for a nutrient boost—onions love rich soil!
4. Water Source
A spray bottle, small watering can, or hose with a gentle stream works great. Keep the soil moist but not soggy.

Quick Tips for Fast Growth:
Sunlight is Key: Place bottles near a sunny window or on your balcony. Onions need at least 6 hours of sunlight daily.
Vertical Planting: Cut small holes along the sides of the bottle and tuck onion sets into each one. You’ll maximize space and yield!
Feed Occasionally: Use a diluted liquid fertilizer every 2 weeks to speed up growth.
Harvest Smart: Once green shoots are about 6 inches tall, snip them off and let the bulb continue growing—or harvest when bulbs are thumb-sized.

Bonus Tip: Start a new bottle every 2 weeks for a constant harvest cycle. With a few bottles, you’ll never need to buy onions again!
