Can you grow lychee from seed? Yes. To grow lychee from seed, sow it within a few days of eating the fruit, because it dies once it dries out. Plant it 3/4 inch (2 cm) deep in moist, airy mix and keep it warm. Expect a houseplant, not quick fruit: seedlings may take 10 or more years to bear.
Key takeaway: Lychee seeds are recalcitrant: sow fresh, keep moist, and treat seedlings as long-term ornamentals or rootstocks.
| Step | What to do | Why |
|---|---|---|
| 1. Pick fresh fruit | Use fully developed, plump seeds | Shriveled “chicken tongue” seeds are not viable |
| 2. Sow fast | Within a few days of eating | Viability lasts about 4 to 5 days |
| 3. Soak | Optional overnight soak in clean water | Soaked seeds germinated better in trials |
| 4. Plant | About 3/4 in (2 cm) deep, on its side | Best emergence in HortScience tests |
| 5. Keep warm and moist | Shaded, humid, well-drained mix | Drying kills the embryo |
| 6. Protect from cold | Above 32°F (0°C) | Young trees are damaged at 28–32°F (-2 to 0°C) |
Why Must You Plant Quickly to Grow Lychee From Seed?
Because it cannot survive drying. Julia Morton’s Fruits of Warm Climates, hosted by Purdue, says lychee seeds remain viable only 4 to 5 days. Researchers call such seeds recalcitrant. In a HortScience study by Prasad and colleagues, delaying sowing after removing seeds from the fruit significantly reduced germination in all four cultivars tested.

Which Lychee Seed Should You Choose?
To grow lychee from seed, pick the biggest, plumpest seed. Morton notes many prized fruits carry shrunken, partly developed “chicken tongue” seeds, and the choicest types have abortive, non-viable seed. A full, glossy, dark-brown seed is your best chance. Rinse off the sweet flesh so it does not mold, but keep the seed damp from the moment you remove it.
How Do You Grow Lychee From Seed Step by Step?
Soak, then plant shallow. In a 2015 HortScience study, Zhang and colleagues found that most cultivars germinated better after soaking in water, reaching over 90 percent with 26 to 54 hours of soaking. Seedlings emerged best when seeds were sown 3/4 inch (2 cm) deep, lying flat on their sides.
- Rinse the seed and soak it in clean water overnight or up to about two days.
- Fill a 4 inch (10 cm) pot with a moist, well-drained seed mix.
- Lay the seed on its side about 3/4 inch (2 cm) deep.
- Keep it shaded, warm and evenly damp, never soggy.
- Move the seedling into brighter light once leaves open.
Our guide to hydroponic germination methods covers warmth and moisture control for any seed.
What Temperature Helps Lychee Seeds Germinate?
Warm, humid conditions. Prasad’s team got the highest germination in shaded, humid sand held near 95°F (35°C), while sun-baked sand and soggy shaded soil failed. Zhang’s team found brief presprouting temperatures above 108°F (42°C) harmed later growth. Aim for a warm, bright room or heat mat with good airflow, not a hot windowsill.
How Long Until Lychee Grown From Seed Fruits?
When you grow lychee from seed, fruit often takes a decade or longer. UF/IFAS Extension says lychee trees do not come true from seed and seedlings may take 10 or more years to bear. Morton cites 5 to 12, even 25, years. That is why growers use air layers, which can fruit 2 to 5 years after planting, or graft onto seedling rootstock.
To get a fruiting-age plant faster from a mature tree, read our guide to air layering.
Can a Lychee Tree Grow Indoors or in Cold Climates?
Yes, you can grow lychee from seed as a container plant, with protection. UF/IFAS reports young trees are damaged at 28 to 32°F (-2 to 0°C), and fruiting needs a cool but frost-free winter. Indoors, give the brightest window or a grow light, a deep pot with drainage, and steady moisture. Expect foliage, not fruit, in most homes.
Similar care applies to a hydroponic lemon tree kept indoors through winter.
Why Is My Lychee Seedling Dying?
When people grow lychee from seed, losses usually come from drying, cold or soggy roots. Morton notes lychee has a high water need but cannot stand waterlogging. Water when the top inch (2.5 cm) feels barely dry. Morton gives a soil pH of 6 to 7 as suitable, and notes seedlings in an early greenhouse test grew best in acid soil.
FAQ: Grow Lychee From Seed
How long does a lychee seed stay viable?
About 4 to 5 days once removed, per Morton.
Should I dry the seed first?
No. Drying kills lychee seeds.
How deep do I plant to grow lychee from seed?
About 3/4 inch (2 cm), on its side.
Will a seedling taste like the parent fruit?
Not necessarily; lychee does not come true from seed.
Can I eat the seed?
No. Morton describes the seed as inedible.
