Thrifty Science: Growing an Avocado Houseplant

We made a big batch of homemade guacamole yesterday, so I saved the 4 avocado seeds in hopes of trying to grow our own avocado houseplants.  I figure it will make for a great hands-on, FREE science lesson for Luke (age 4) and Lilah (age 2) to watch the roots and stem start to grow from the seed.  We are all about thrifty preschool lessons! 🙂

How to grow an avocado plant from a seed


Here is the website with the directions for what to do.  It’s really simple and all you need are an avocado seed, toothpicks, a glass, and water.  We didn’t have toothpicks, so we broke off wooden skewers and used those instead.

We followed the directions on the California Avocado Commission’s website


We just started ours today, so I’ll post again when — if!!! — they start to grow!  If they don’t grow, we’ll just buy more avocados and try again.  We LOVE guacamole!! 🙂

Have you ever grown an avocado plant?

    I grew an avocado plant. It was 2 1/2 feet tall, it was fun!

  • Wow! That’s encouraging. Any tips? I hope at least one of our 4 seeds will take off!

    Dear Anonymous. Did you yield avocados on your plant? Did you grow it fully indoors? What area of the US do you live? I’ve done this experiment as a child, it grew a few roots, but the seed just molded in the dirt.

  • I really have to try this next time I buy avacados! Don’t you just LOVE homemade guacamole?!

    Just curious if this method actually yields fruit. I should also mention that you are actually growing a tree that should be later planted outdoors. I would recommend using an avocado variety from Mexico as most others are not tolerant to the cold and freezing of the U.S. These would be the only varieties most likely to bear fruit and only in southern regions.
