Foods You Can Grow From Scraps!

Post image for Foods You Can Grow From Scraps!

Sometimes I feel sorry for the left over bits of fruits and vegetables that I throw out. For something so fresh and good, it seems like every part of it should be used. Believe it or not, you can. Not only is this a great summer project, but it will also save you some money: there are several fruits and veggies that you can regrow, right at home, with only their scraps!

You might be surprised by some of the fruits and veggies you can actually regrow. The pineapple definitely took me by surprise, along with some of the others listed below.

fruits and veggies






Green Onion

Romain Lettuce

Potatoes/Sweet Potatoes


Bok Choy



All you need are some pots and soil, glass jars, toothpicks, sunlight, and a windowsill!

glass jars

To start the process, most of the foods listed above need to be soaked in water. I collected a few jars around my house, and gathered a few toothpicks. I decided to grow pineapple, avocado, and green onion.

Take the pit from an avocado and submerge the rounded end in water. I stuck 4 toothpicks around the outside so that they would rest on the outside of the glass jar to keep the pit in place.

You do the same thing for the pineapple, but this one is a little trickier to prep. First, remove the root. The best way to do this is to grab the base where the leaves start, then twist and pull up. Any excess fruit that is left will only rot in the growing process, so make sure to cut all of that away. Once your pineapple looks something like the above photo, you can stick toothpicks in around the base and place in a jar so that the portion of the root below the leaves is submerged in the water.

For the green onion, simply place in a jar with the white root portion submerged in water.

Now, all it takes is a little patience! When the water starts to look dirty, you can change it as needed. When roots begin to grow, you can transfer your fruits and veggies to a pot with soil.

Once planted, place them in a spot where they can get direct sunlight.

Yep. I’ve successfully regrown green onions, celery, and I’m currently working on two avocados. I like avocado plants since they have kind of elegant leaves, so even if I never get a tree that produces fruit I’m still happy to have it as a houseplant.

I’m gonna have to try this! Love the pineapple!

We re-grow beets (yummy leaves), celery, basil, lettuce, and alfalfa sprouts, but I’m eager to try ginger and garlic since we run out of these so often! Potatoes in a barrel sound like fun for the kids too. One thing to keep in mind, though, is that produce is often sprayed with sterilizing chemicals so be sure to buy farm fresh to ensure your scraps will reproduce.

This is amazing! Totally going to start some beet and lettuce houseplants!

I have always wondered if this could be done. I’m so excited to find out that it can be. Yay!! I can’t wait to grow my own avocado!!!! Thank you so much for this awesome post.

love the post! I’ve been regrowing green onions for about a year now – totally easy to do. I had in my plan already to try garlic, but I love that you said it can also be done with ginger (I’ve got one in the fridge that will need a new home soon lol)

Oh this is lovely, and I have always wanted to try this! I knew about some like the lettuce, but avocado is a surprise to me, I can’t wait to hear about the progress!

Maxime -June 17, 2014, 3:29PM

I love doing this with the leftover basil given to me when ordering pho. I now have tons of basil plants!

My dad constantly regrows avocados! We have a lot of them hanging out in the sunroom. Be careful, they’re VERY temperamental in the beginning.

Brooke -June 17, 2014, 9:09PM

wow! that is amazing! definitely have to try this!

Carigan -June 18, 2014, 8:30AM

I have done this so many times with green onions, But I will try avocado next time. really neat.

Lisa -June 18, 2014, 9:26AM

Love this!!

Cassie -June 18, 2014, 9:55AM

Love this post :)

I found out something similar about the green onions last year from a friend of mine. I’ve never tried growing them from stubs before, instead I stick the onions in a glass of water as soon as I bring them home from the store. The outermost piece of onion always dies, but after pulling that off it just keeps growing. They used to disintegrate in my fridge after a couple days, now they live on my counter for weeks at a time, and I just cut off pieces of onion as I need them.

Great post I have to try this out, thanks!

jessi -June 19, 2014, 10:54AM

tasxxx -June 23, 2014, 10:10AM
