Regrow Veggies From Scraps

This is a very easy and cost effective way to regrow some veggies from your kitchen scraps!

No room for a garden? Try this instead! In this post, I will show you how easy it is to regrow some veggies from your food scraps! This is a great way to limit waste, save some money, save space, and have some veggies always on hand.

All you’ll need are some jars, cups, or containers to fill with water, some food scraps, and a sunny area to place your veggies.

The Veggies

There are quite a bit of veggies that you can regrow from kitchen scraps. Here is a few that you may have on hand or may try in the future.

  • Carrots
  • Green Onions
  • Onions
  • Radishes
  • Potatoes
  • Sweet Potatoes
  • Celery
  • Garlic
  • Shallots
  • Leeks
  • Bok Choy
  • Romaine Lettuce
  • Cabbage
  • Fennel
  • Daikon

What To Save

When cutting your veggies, make sure to keep at least a half inch to an inch above where roots will begin to form. This is the portion that you will save to create your new plant from. You can save the bottom portion of your cabbage, celery, onions, green onions, etc. Pretty much any veggie that will have an end that roots had once grown from.

You can also save at least an inch of carrot, right where the carrot tops will grow from. The carrots won’t develop more carrot, but will regrow carrot tops that you can use to saute or make pesto with. You can save portions of cut potatoes, but just be sure to keep the skins on. If you have fresh herbs like basil or mint, you could place those in water too. I’ve heard they can sprout roots this way as well.

Getting Roots And Shoots

Once you have your end pieces saved, you can now place them into water. I recommend using small shallow dishes since you only want a small portion of the root section to be submerged. Submerging the whole cutting into water will cause it to rot. When rooting potatoes or ginger, submerge halfway into water. Be sure to change out the water every 3 days or so to prevent bacterial growth and rot. Place next to a sunny window and watch the magic happen.

Some veggies will develop leaves and growth much faster than others. My green onions and celery started to grow back in a matter of days, where potatoes takes much more time for buds to develop. You will usually see some growth within a week or two. Patience is key and before you know it you will have lots of fresh veggies at your disposal.

Some veggies will naturally start developing sprouts or leaves even before you place them into water. This makes it very easy to plant directly into soil or you can place into water, submerging only the root system. A lot of times you will see potatoes forming buds from their eyes, or garlic and onions forming leaves. If this happens you can save the whole garlic, onion, potato, etc. and place directly into soil. You could also just place into a shallow dish of water if that is more convenient for you.

Transferring To Soil

Once the plant grows to be of a substantial size with roots, you can transfer it into soil. When you transfer to soil, keep your plant relatively moist to get accustomed to its new potting medium. If planted outdoors, take note that insects and other critters may get to your veggies before you do, so you will have to be much more observant.

When planting potatoes, you can cut them into fourths and plant the pieces, or plant whole. I like to submerge mine into water halfway to get it to sprout. Be sure that when you cut your potatoes, leave the skins on, and let them callous over before planting. This will prevent rot.

When planting ginger, I plant mine flat with the buds facing upward. I recommend keeping ginger indoors since it is not cold hardy.

Overall this is a very fun and easy way to make more from what would have been waste. There are so many different vegetables that you can try and experiment with. With Covid keeping everyone at home from school and work, it is a great project to try with kids. Kind of like a cool science project. Hope you enjoy and happy gardening!
