Once you learn how to grow citrus trees from seed, I am not going to lie – it becomes pretty addicting. So here I am, ready to tell you all about how to grow a grapefruit tree from seed.
We don’t eat a ton of grapefruit here, but I’m bitten by the citrus growing bug, so why not?!
The grapefruit I cut open had only 3 seeds inside but they all looked plump and viable. We’ll see how it goes!
First, get yourself a fresh grapefruit and then follow along with these easy steps.
Planting Grapefruit Seeds
It’s easy to learn how to plant a grapefruit tree from seed. If you’ve read any of my other posts on starting citrus from seed, this is old hat. 🙂
First, you’ll collect the seeds and germinate them in damp paper towels. Then, you’ll transfer the sprouted grapefruit seedlings to some soil. Easy peasy!
To germinate grapefruit seeds and plant a baby tree, you will need a few materials.
Gather a fresh grapefruit, knife and cutting board for seed harvesting.
For grapefruit seed germination, gather the seeds, a paper towel, a sandwich bag with zip-top, a permanent marker, and water or a spray bottle filled with water.
How to Grow a Grapefruit Tree from Seed
It’s so exciting to dream of all the different indoor citrus trees we can grow! Follow these easy steps to plant a baby grapefruit tree.
It should only take you a few moments for each phase of the process. 🙂
Collecting Grapefruit Seeds
Harvest some grapefruit seeds during your breakfast or when you go to squeeze some fresh grapefruit juice!
- Shallow-cut a grapefruit in half across the hemisphere to reveal the pretty sections.
- Twist to separate the two halves.
- Remove any loose seeds and set them aside.
- Look inside the halves for more seeds.
- Squeeze the juice or enjoy your grapefruit. Remove any other seeds that you find.
Germinating Grapefruit Seeds
Once you have grapefruit seeds, move on to germination.
- Gently nick the outer seed coat using your thumbnail.
- Carefully peel away the rough outer coating of the seeds.
- Set aside the peeled grapefruit seeds until you are done with all of them.
- Fold a paper towel in halve and dampen it.
- Place the seeds on top so they are not touching.
- Spray a bit more water to evenly moisten the seeds.
- Fold the paper towel and place it inside a zip-top sandwich bag.
- Seal the bag and write the grapefruit variety and the date with a permanent marker.
- Set the baggie somewhere out of the way where it is a bit warm. I placed ours on top of the microwave.
Check on the seeds after about 5 days to a week to spot signs of successful germination.
Transplanting Grapefruit Seedlings to Soil
After the seeds sprout, you can move the seedlings to a small pot with some soil!
- Gently remove a sprouted seedling from the baggie.
- Prepare a small flower pot with a coffee filter to catch the soil bits and then fill with damp potting soil.
- Make an indentation in the center for the baby grapefruit tree seedling.
- Cover with soil and water adequately.
- Repeat for any additional germinated grapefruit seeds you would like to try growing.
- Place the pots in a sunny window or under some grow lights.
Check regularly for watering needs and signs of continued growth!
Growing a Grapefruit Tree from Seed
Where we live, citrus trees cannot survive our winters. That means I have to make room for all these babies inside the house!
It’s going to be a jungle in here pretty soon, and I love it!
(Sorry hubby. Well, sorry, not sorry, I guess! These plants make me so happy!!)
