How to Grow Clementines & Mandarin Oranges From Seeds
A variety of Mandarin orange widely grown in the Mediterranean region and the United States, Clementine oranges (Citrus Reticulata ‘Clementine’) can be grown from seed in the same way as any other variety of Mandarin orange. Best suited to U.S. Department of Agriculture plant hardiness zones 9 to 11, Clementines cannot tolerate freezing temperatures. Clementine and other Mandarin orange trees can be easily grown from seed.
Remove the seeds from the fruit. Rinse the seeds under lukewarm tap water. Rinse off any juice and remove all fruit flesh from around the seeds. Any fruit left around the seeds will rot when planted in the soil and could result in mold or fungus that might destroy the seeds.
Place the seeds in a cup of lukewarm tap water and let them sit for 24 hours. Although soaking the seeds in water before planting is not necessary for germination, it does increase the chance of the seeds germinating successfully. Note: If you do not intend to plant the seeds right away, dry them completely and then put them in an airtight container. This prevents the growth of microorganisms. Storing them in cool or even cold location until you’re ready to plant is also essential to prevent seed destruction.
Plant each seed into a 3-inch pot. Plant the seed 1/4 to 1/2 inch deep into a rich but well-drained potting soil with a neutral or slightly acidic pH balance. Water the soil of the pot until it is soaked and let it drain.
Cut one or two small holes into a small transparent bag. Place the bag over the top of the pot so that it acts as a barrier, keeping heat and moisture in over the surface of the pot. Secure the bag in place, if necessary, with an elastic band around the base of the bag and top rim of the pot.
Place the pot near a bright window or outside on a bright balcony where it will receive a few hours of direct sunlight each day. Remove the bag to water whenever the surface of the soil appears dry.
Remove the plastic bag after the seedling emerges and outgrows the space provided within the bag. Water the seedling whenever the surface of the soil appears dry.
Transplant the small tree after roots appear around the drainage holes of the pot. The Mandarin seedling can be planted in a larger pot for patio or even indoor growing, or outside in an area of the yard where it will not be crowded or shaded from direct sunlight.

Why Did I Find Seeds in Seedless Cuties or Halos?
Whether you call them Cuties, Halos, Clementines or whatever marketing name with a smiling fruit on the box, they are all mandarins. And they are all suppose to be seedless, right?
The marketing appeal of these fruits is that they are easy to peel and you don’t have to worry about seeds.
So how many of you have bite into one of these things and on occasion found yourself spiting out a seed or two?
What gives? Are they lying to me? How did this happen?
At some stores you will find Halos and Cuties both at the same time. Stores sometimes get Halos in one shipment, then Cuties in the next shipment. Such was the case when I took this photo at Costco.
Clementines are Not Truly Seedless
During the early part of the season the Clementine variety is the type of mandarin you find in Halos or Cuties packaging. This variety isn’t actually seedless. If left to grow on it’s own you would find seeds in the fruit. This happens when bees visit the fruit and cross-pollination tastes place. So why isn’t every fruit full of seeds? In order to produce a seedless product the growers prevent the bees from cross-pollinating with more than 1 variety of citrus. There are 2 ways to counteract this. You could grow each variety in isolation from other varieties. As you can imagine this isn’t always easy or possible. A second option is put netting over top of the tree as you will see in my photos below taken in California.

Of course there is the possibility that a bee or two will get through and still pollinate a flower in either option. This is why from time to time you are going to find seeds in your fruit. Can’t expect a 100% success rate, but not the less it is pretty high, enough for them to still label them as seedless.
Murcotts are Also Not Truly Seedless
Later on in the season, Halos and Cuties switch over to the Murcott mandarin, although most people seem to miss that. This variety also would be full of seeds if measures are not taken to prevent that.
Pixies are Truly Seedless
Not all varieties of mandarins have seeds. The Pixie mandarin is genuinely seedless. Even if cross pollination takes place it will not make seeds. The best Pixies are grown in the Ojai Valley of California and are available near the end of the season, starting usually in March. So why don’t the Cuties or Halo growers use varieties like this one? The Pixie variety has not undesirable traits too like producing heavy one year and light the next, that makes it less than ideal. Plus Pixies seem to only be of great flavor when grown in the Ojai micro-climate.
Now I know. I have a habit of planting seeds in pots just to see if they will grow. I planted 4 seeds from one of the varieties and now have plants ranging from 3-4 feet tall. I have them in pots right now and bring them in for the winter months.I know they are root bound. We have a place in Jacksonville and plan on planting them there this spring to see what happens. Summer before last I had 2 blooms that produced 2 tiny fruits but fell off before they grew any size. They have not bloomed since then. I can see why they cost so much. The thorns on them are long and hurt when you get pricked with one.
That is fun to do for sure. Never know what you are going to come up with. By doing that you might end up with something great or you end up with 2 tiny fruit that fell off before they grew. You just never know. Seems like you are having fun doing it.
In a Halo clementine I found 30 seeds in one clementine. I felt that was an unusually high number of seeds.
I just found a Halo with 4 of the slicss containing 3 or more seeds in the tiny slice.. per slice..
Not surprising. Clementines are not seedless and that is the variety in Halos right now. A bee must have paid a visit.
That is a crazy amount. Not surprising. Sometimes the bee makes it through and pollinate those clemetines.
Just finished a Halo with 34 seeds in it. Each tiny slice had 3-4 seeds!! It was super sweet and juicy so I made it work… but worrisome if a little kid had gotten it.

Nice to Meet You,
Hi! I’m Eric : Father of 4, living just south of Ann Arbor, MI. I’m a reformed picky eater finding a new way to not conform. Eating what’s in season is my jam (I also make it!)
