How to re-grow your kitchen waste into more food!
Posted on November 05 2019
Did you know that there are some kitchen scraps that can be re-grown into new plants? It's the cheapest food you will ever grow - free!
You may have seen these ideas pop up in your feed before (and you may have even tried some) but I am going to run through a couple that we do that are super easy and pretty much fool proof. I will also let you know which ones I think are a bit harder or impractical and why.
The (Pretty Much) Fool Proof Scraps to Re-Grow
Ok so starting with the easy ones. These ones are super duper easy to grow. Trust me, you have to try these ones!
Spring Onions (aka shallots)
You know those ends with the white bits on them that you don't use? The bits with the roots still attached? Don't throw them away as they are really easy to turn into new spring onions!
You will need: 1. your spring onion ends and 2. a jar with water. That's it!
Place your spring onion ends into a jar and fill with enough water to cover the ends, but leave the tops out of water.
Find a little spot on your kitchen bench and wait for your new onions to start growing. Change the water frequently (it gets a bit gross and slimy otherwise). You should start to see the new ones pop up in a few days. They will grow as a thinner onion from the middle.
I like to keep them growing in the jar in our kitchen and trim off to use as garnish when needed. But you can re-plant them into the garden once they have grown roots and grow into a full plant. You can usually re-grow your spring onion ends 2-3 times but each time it gets thinner and thinner.
Bok Choy and other Asian Greens
This is another one that is really easy to re-grow using the bottom part you don't usually use when cooking.
You will need: 1. your Asian greens end (in tact) 2. A bowl or dish and 3. some paper kitchen towel
Dampen your paper kitchen towel with water and place folded up in the bottom of your bowl / dish. Place your Asian greens on the paper with the bottom facing down (so former leafy side facing up).
Keep the paper damp and in no time you will start to see new leaves growing! You can then plant your re-growing Asian greens in the garden or keep in your kitchen and cut off and use the new leaves as they grow.
The Impractical or Too Hard Ones (but good for a bit of fun)
This is one that is impractical, in the sense that you won't get any new avocados to eat! but it can be a bit of fun. If you manage to get one growing that is, as they can be a bit tricky. A popular method is to put an avocado seed on some toothpicks into some water.
So you may be wondering why you won't get new avocados growing from your new avocado seed tree? Well technically you might but it will take about 15 years and that's if it survives that long they are notoriously tricky to grow.
I have included celery in the impractical section because it takes a long time and fussy conditions to grow a full celery plant. So I don't think it is practical for the every day non-expert level gardener. But if you are interested in growing for the leafy tops (I can't think of a reason why these would be useful?) or a teeny tiny plant then give it a go.
Why is it impractical? It takes 5 months to grow a full celery plant, it needs a lot of water, nutrients and certain type of soil plus it can only grow in cooler weather.
Is there anything you like to re-grow? get in touch and let us know!
Another thing we love to grow is ginger and other roots. But I will do a seperate post on this as I don't think they are technically scraps, but it does use store bought produce.
