How to regrow food from kitchen scraps

They say there is no such thing as a free lunch. I’m here to prove that wrong, but this free lunch will only consist of regrowth of spring onions.

Okay, maybe it's just a free snack or garnish. But, hey, it’s still free, happy days.

This is SO simple, it takes zero skill. If you are far from green fingered, I promise you can still do this. It's even more forgiving than keeping a succulent- and you only need to think about it every few days for a couple of weeks. If you’ve used up all your maternal plant love by then, you can eat all of the spring onions, or you can snip the regrowth and watch them resprout.

A Zero Waste Life. Regrowth

You’ll need to start off with spring onions (obvs, nothing comes from nothing) but these spring onions can be pretty old. We experimented with some very ropey looking spring onions from Annas fridge, and they did just fine. You’ll need to trim your onions about an inch from the roots. Those of you who don’t know what the heck an inch is, trim about 3cm.

That is the part that needs to be in water. Fill up an old jam jar or alternative water vessel and place the onions and jar in a sunny spot like a window sill. Only the roots need to be in the water, the top part will be out of the water, ready for growing.

Eat or compost the rest of your spring onion. Eating is better, but I couldn't face eating those onions we took from Annas fridge, as they were well old, so we fed them to her wormery worms.

Every three days (ish), take a look at the onions, change the water as needed and snip off any onions you want to eat. You might want to peel off the outer layers of the spring onion, if you can tell they won’t regrow and are looking dry and icky.


Here are the instructions if you totally didn’t want to read my anecdotal ramblings above.


You will need:

Scissors

Glass jar

Spring onions (this works with some other vegetables too, take a look at the bottom of this article.)

Instructions:


1.Trim the onions 1 inch/ 3cm from the root. Eat or compost the spring onion ‘stems’

2. Place the root ends downwards in a glass jar, and fill with water. Not much water is needed, just enough to cover the roots

3. Place the jar on a sunny window sill

4. Every few days, check the jar. Trim off any regrowth you want to eat and change the water when needed.



Other veggies that I have tried this magic on are:

  • Celery

  • Bok Choy

  • Onion

  • Leek

  • Romaine Lettuce

I have also tried Beetroots, Carrots and parsnips. They regrow their leaves easily, but not the whole vegetable, like I first thought they would.

The internet gods also tell me that you can regrow the following, though I’ve not tried these, so you’ll have to just believe them.

  • Garlic

  • Lemongrass

  • Ginger

  • Sweet potato

  • Coriander

  • Rosemary
