How to Grow Clementines & Mandarin Oranges From Seeds

Related Articles

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.

Halo seed. Will it grow?

I read somewhere on this forum that some seeds from commercial growers are sterile. Anyone know if this is the case with Halo mandarin orange seeds? I plan to try it but need a few pointers. First, do I need to let it dry out? Second, do I peel the skin off the seed or do I risk damaging it or leave it on and just scar the outside? Third I don’t really have seed starting soil or citrus mix but I have a lot of plain ole potting mix will this be okay? Or is all of this futile because the seed is sterile?

What. Patty get your shoes on and head on down to the local grocery store RIGHT NOW. lol. just kidding. Halo’s are a brand name not so much the cultivar. Like Dole and Chakita I believe. Someone correct me if I’m wrong. These lil mandarins are the absolute best tasting tiny oranges I’ve ever had the chance of sinking my teeth into. I bite slightly into the thinnest part of the wedge and suck its tarty sweetness like a vampire until it’s bone dry then gnaw on the left overs. I’ll devour 4-5 of these before breakfast is even fully cooked. 😛 I strongly recommend trying at least one. When you do lemme know what you think.

Not necessarily true, nerdish. I have not actually heard that. Commercial growers will often grow citrus in large blocks, to reduce the number of seeds produced by cross pollination. Have no idea what Halo mandarin is, that is not a cultivar I am familiar with. Do not let citrus seeds dry out. They should be planted shortly after removing from the fruit. You can carefully remove the outer casing if you want, to speed up sprouting. I would start in well draining soil. Potting soil might be a bit dense. You can use seed starting potting mix, then move to a better draining mix as the seedling grows larger.

I strongly suggest ordering a grafted plant from a reputable nursery. Get a mandarin orange, as they are the ones you so desperately love. Of course it’ll be about a year before you can get fruit even from a three year tree, but in the long run it will be worth the effort and money! And it will taste way better than those store bought halos, which IS possible.
A graft is two plants surgically connected, one acts as roots, the other flower and fruit! Reasons for this are productivity, disease resistance, cold hardiness.
Best of luck.

Nerdish, they are not “Halos”. This is a marketing term for some current cultivar ripening at this time. Halo is not a cultivar 🙂 Like the term, “Cutie”, which is also not a cultivar, but actually one of 3 possible cultivars, depending on the time of year. Probably Clementines, If they’re pretty small, they could be the Seedless Kishu. If they have a few seeds, then they most likely are Clementines. Also, mandarins are not oranges. Oranges are oranges. Mandarins are mandarins 🙂 Two different types of citrus. Just like a lime isn’t a lemon. You can try growing from seed, just know it can take many years before the seedling will produce fruit.
