Can you grow an orange tree from seed? Yes. To grow an orange tree from seed, clean seeds from a ripe fruit, plant them 1/4 to 1/2 inch (13 mm) deep in sterile mix, and keep them warm and moist; UF/IFAS says sprouts appear in 2 to 3 weeks. Fruit may take 10 to 15 years.
Key takeaway: You can grow an orange tree from seed, and it is a good project, but it is slow. UF/IFAS Extension says many citrus seeds are polyembryonic, so one seed can give several sprouts, most of them clones of the mother tree. UC Master Gardeners of Napa County say seed-grown citrus can take 10 to 15 years to fruit, versus a few years for grafted trees.

Can You Grow an Orange From a Store-Bought Seed?
Yes, if the seed is plump and comes from ripe fruit. Many grocery oranges, such as navels, are seedless, so look for fruit with seeds. UF/IFAS says seeds from many citrus varieties are polyembryonic. Their nucellar seedlings are genetically identical to the mother tree, so a seed-grown orange tree often resembles its parent.
- Pick plump, white seeds; skip flat or shriveled ones.
- Rinse the fruit first: UF/IFAS suggests disinfecting fruit before extraction to avoid disease.
- Plant several: some will fail.
UC Master Gardeners add that the one weaker sprout is usually the sexual (zygotic) seedling, which can differ from the parent. Pull it if several sprouts appear.
How Do You Germinate an Orange Seed, and How Long Does It Take?
Plant clean seeds shallowly in warm, moist, sterile mix. UF/IFAS recommends 1/4 to 1/2 inch (0.6 to 1.3 cm) deep and says that removing the seed coat or soaking seeds in aerated water for about eight hours shortly before planting can speed germination. Under ideal conditions, seedlings emerge within two to three weeks.
- Wash pulp off the seeds and rinse well.
- Optional: peel the thin outer coat with a fingernail.
- Plant 1/4–1/2 in (0.6–1.3 cm) deep in seed starting mix.
- Keep the mix warm and evenly moist, not soggy.
- Give bright light once sprouts appear.
UF/IFAS notes that commercial growers dry seeds before planting for best germination. For warmth, see seed germination temperature.
How Do You Care for an Orange Seedling in a Pot?
Keep a young orange tree from seed warm, bright and in a draining pot. UF/IFAS trains nursery seedlings to a single stem with no branches in the lowest 6 to 8 inches (15 to 20 cm). At home, move the seedling up one pot size at a time and give it full sun or a strong grow light.
- Light: a south window or grow lights for citrus trees.
- Water: when the top inch dries.
- Roots: repot before roots circle.
- Feeding: a citrus fertilizer once it has several true leaves.

Will an Orange Tree Grown From Seed Ever Fruit?
An orange tree from seed fruits eventually, but slowly. UF/IFAS says seed-grown citrus usually does not fruit for many years because of juvenility. UC Master Gardeners of Napa County say it can take 10 to 15 years before a seed-grown citrus is mature enough to fruit, while grafted trees from mature wood bear within a few years.
- Want fruit sooner? Buy a grafted tree or graft mature budwood onto your seedling.
- Rules: UF/IFAS notes Florida requires certified disease-free budwood for citrus propagation; check your state.
- Enjoy it as a houseplant while you wait; the leaves are fragrant.

Why Is My Orange Seed Not Sprouting?
Most failures come from dried-out, cold or rotten seed. UF/IFAS says seeds need sunlight, warm soil and enough moisture to emerge in two to three weeks, and that dried seeds are stored at 40 to 45°F (4 to 10°C) in plastic bags. Planting too deep or in heavy, wet soil can also stall an orange tree from seed.
- Too cold: keep the pot warm; a heat mat helps.
- Too wet: soggy mix rots seeds; let it drain.
- Too deep: stay within 1/4–1/2 in (0.6–1.3 cm).
- Old seed: use fresh seed from ripe fruit.

FAQ About How to Grow an Orange Tree From Seed
How long does it take to grow an orange tree from seed?
Sprouts in 2–3 weeks; fruit may take 10–15 years.
Do orange seeds need to dry first?
UF/IFAS says drying generally improves germination.
Why did one seed make several sprouts?
Citrus seeds are often polyembryonic.
Will the fruit taste like the parent?
Nucellar seedlings are clones, so often yes.
Can I keep an orange tree from seed indoors?
Yes, with strong light and a draining pot.
Should I soak orange seeds?
UF/IFAS says about 8 hours in aerated water can help.
