Here’s a great way to have fresh chives all year round. Just cut the longest ‘leaves’ each time you need to add some rich flavor to your cooking! A DIY onion planter is an easy project that your children will enjoy as the results are very obvious, very quickly.

If you love to cook you know that nothing beats the flavor of fresh onions for your salads, dips, or soup. Wouldn’t it be nice if you can just pluck them straight from your onion planter without even walking outside?

But why bother growing onions when they’re available all year round from the supermarket? For one thing, store-bought produce is hardly fresh. In most cases, there’s no way of knowing where they came from or how long they have been stored. You also have the comfort of knowing your product is free of herbicides and pesticides. Another benefit is that there’s no waste because you only cut as much as you need and the final benefit is that you get to save money as you don’t have to buy them.

This project shows you how you can have all the chives you want right on your windowsill! All you need is a plastic bottle, which you can get for free, and the following items.

What you need to make a DIY Vertical Onion Planter


  • Big Plastic Bottle (5-Liter)
  • Soil
  • Onion Sprouts
  • Water


  • Cutter
  • Heated Metal (optional, for making holes)

How to make a DIY Vertical Onion Planter

It all boils down to growing your own onions. The good news is that you don’t need a huge backyard.

  1. First, remove the bottle’s neck using a cutter.
  2. Using a scissor, create holes that will fit the onion sprouts around the bottle.
  3. Place the soil and onion sprouts
  4. You may return the bottle’s neck using ordinary tape, this is optional.
  5. Place the DIY onion planter on your windowsill. 
  6. Water it regularly
  7. Within a few days, the onions will grow out of the bulbs, and you can now use them in your kitchen!
