If you are looking for a fun way to keep the kids busy and learning at home while also reducing your food waste and trips to the grocery store, look no further than these ideas on regrowing your fruits and vegetables. 

Our recent podcast host, Tanya Acosta, who talked to us all about mastering distance learning in Episode 51 of The Healthy Family Project even provided us with a fun free downloadable you can use to turn this into a true science experiment. 

We are trying a few of these in our house like green onions (which I think is the easiest) and even celery. Join us in the Healthy Family Project Facebook Group to show us what you are growing or leave us a comment here. 

Green Onions 

  1. Chop off root ends (about 2 inches) and place in small glass with an inch of water. 
  2. Refresh water every few days and watch your green onions regrow within days. 
  3. Cut off as needed from the top. The green onions will continue to grow if left in water.


  1. Chop off the base of the stalk, rinse it and put it in a shallow cup of warm water in a well lit area. 
  2. Change the water every few days. 
  3. You should see significant signs of growth within five days or less, depending on how much sunlight you have available.  


  1. Set the top of your pineapple aside and allow to dry for a day or two. 
  2. Once dry, plant in soil. Depending on your soil and daily temperature, you can choose to plant in the ground or in a pot. If you are somewhere that doesn’t allow for warm weather year-round, you can grow your pineapple in a pot indoors, but they do need about six hours of sunlight a day. 


  1. Remove the seeds from your tomato, soak for about an hour.
  2. Allow to fully dry and plant in soil within seven days. If it’s not quite spring yet in your home, you can start your seeds indoors in an old egg carton or other small container and plant outdoors when you are ready. Your kids will be astonished to see you grew a tomato from your tomato!


  1. Cut potatoes so that each piece has at least two “eyes.” 
  2. Let them sit out at room temperature overnight until they’re dry. 
  3. Plant them in soil 8 inches deep and spaced 1 foot apart.


  1. Clean pit and remove any avocado remains. Towel dry. 
  2. Push 4 toothpicks into the pit to create an X (you’ll want to place the pit pointy side up in the next step). 
  3. Place avocado pit over small bowl or glass jar (pointy side up) using the toothpicks to hold it up. Add enough water to the bowl so that half of the pit is submerged. Place in sunlight and change water every 1-2 days. 
  4. After about 3-6 weeks, the pit will begin to split open. In a few additional weeks, a stem, leaves and root will begin to grow. 
  5. After about 3 months, when the “tree” is about 7-8 inches, plant in a pot.

Romaine Lettuce

  1. Chop off bottom of the Romaine heart, leaving a few inches. 
  2. Place in bowl with ½-inch of water. Keep in a sunny place and change water daily. 
  3. Once it starts to sprout (after a few days), plant those sprouts directly in your garden. Harvest when about 6-8 inches tall.


  1. Cut tops off of your carrots. You’ll need about an inch of the root.
  2. Stick toothpicks into carrot tops and place on top of a small glass. Fill with enough water to barely touch the bottom of the carrot top.
  3. Place in a sunny spot and add water daily to keep the water touching the bottom of the carrot top. 
  4. The carrot tops will start to grow roots in about a week.
