The Pomato Plant: A Science Project / Bible Class Lesson for Homeschoolers

Updated on August 20, 2012

As homeschooling parents we often think "outside the box" when it comes to planning lessons for our children. We like to find projects that are educational, fun and character building at the same time. I know first-hand that this can be very difficult. It's hard to come up with new things over and over again without becoming too repetitive. Also, since we usually must fund our own projects and curriculum we have to figure that in the picture too.

This is why I believe that homeschooling families everywhere will love the pomato plant. It's both fun and educational and with a little spiritual creativity you can use it to help build character as well. And the cost is very little monetarily. However, it will take a lot of time and patience! (Patience is a virtue as well ;)

What is a Pomato Plant?

A pomato plant is a plant that is a result of grafting together potato and tomato plants. When you successfully grow a pomato plant, you will reap tomatoes on the top of the plant and potatoes under the soil. You can do this with your children to teach them how grafting works.  However it is possible that even a successful plant may have its limitations. 

What items will I need to grow my pomato plant?

  • One healthy potato plant (6-9 inches tall)
  • One healthy tomato plant (6-9 inches tall)
  • Grafting tape
  • Utility knife
  • Potting soil
  • 2 medium to large flower pots
  • Plastic trash bag

Instructions for growing my plant

  1. First plant your potato and tomato plants in flower pots with potting soil. Grow until the plants have reached 6-9 inches in height. (Or you may buy the plants from a botany shop). Make sure your plants are healthy before you begin the grafting process.
  2. Place plants beside each other and allow the stems to touch. At the place that the stems touch, gently shave the stems on both plants with a utility knife. Carefully join plants together at the shaved part and wrap securely with the grafting tape. Make certain that none of the shaved part is exposed.
  3. Take good care of your plants and watch for signs of new growth. Once the tomato plant has shown good signs of new growth and starts to bush out, gently cut away the potato plant above the place where the graft was made.
  4. Again watch for new signs of growth on the tomato plant. When it begins to bush out again then it is time to cut away the bottom of the tomato plant just below the new graft. (This step requires patience and could take up to three weeks).
  5. Place a plastic trash bag gently over the new pomato plant for a greenhouse effect. (Just long enough for plant to adjust without wilting. About 3-7 days).
  6. Remove the plastic and watch the plant thrive. When you are sure that it is thriving, then remove the grafting tape.

I can use this for Bible class too?

Yes! This is an excellent way to explain to children how we are grafted into the family of God.

We are like a wild plant. Our sin causes us to bear bad fruit. The only hope for us is to be grafted into a Good Vine. Without this Good Vine we will eventually wither away and die. Jesus made the way for us to be grafted in when He gave His life for us on the cross. When we accept this gift we are grafted into this Good Vine and can now bear good fruit. We have now received the spirit of adoption and we become God's children.

Bible verses share:

Jesus speaking...John 15:4 Abide in me, and I in you. As the branch cannot bear fruit of itself, except it abide in the vine; no more can ye, except ye abide in me.

5 I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.

6 If a man abide not in me, he is cast forth as a branch, and is withered; and men gather them, and cast them into the fire, and they are burned.

7 If ye abide in me, and my words abide in you, ye shall ask what ye will, and it shall be done unto you.

8 Herein is my Father glorified, that ye bear much fruit; so shall ye be my disciples.

9 As the Father hath loved me, so have I loved you: continue ye in my love


Galatians 4:4 But when the fullness of the time was come, God sent forth his Son, made of a woman, made under the law,

5 To redeem them that were under the law, that we might receive the adoption of sons.

6 And because ye are sons, God hath sent forth the Spirit of his Son into your hearts, crying, Abba, Father.

7 Wherefore thou art no more a servant, but a son; and if a son, then an heir of God through Christ

      That's great, Miriam! However, I would not recommend eating any fruit that may come of it. I'm not certain what happens to the fruit botanically once it's grafted. Someone told me it was poisonous, which don't make sense. I don't know if it's true, but better safe than sorry!

      I did not realize the pomatos were actually grafted together. I just thought they were planted 'one up, one down'. A very good lesson from this also!
