Even if you reside in an area suitable for growing the rambutan tree, bear in mind that Mother Nature is capricious and you must be prepared to protect the tree from abrupt temperature drops. Also, rambutan trees like a damp environment. In reality, temperature and humidity are essential for producing a healthy rambutan.
- Rambutan trees may be produced from seed or seedling, both of which will likely need to be bought online, unless you have access to fresh fruit in your region, in which case you might attempt to collect the seed yourself.
- For seed to be viable, it must be less than a week old and well cleansed of all pulp.
Plant the seed flat in a small pot with drainage holes and organic soil enriched with sand and to grow rambutan from seed. Place the seed in the soil and cover it lightly with earth. Between 10 and 21 days are required for the seed to germinate. It will be around two years before the tree is ready to be transplanted outside; it will be about a foot (31 centimeters) tall and still delicate, so it is best to repot it rather than plant it in the ground.
How long does a rambutan seed take to germinate?
Growing recommendations for Rambutan trees – If you choose to cultivate Rambutan trees indoors, you must be prepared to shield them from any temperature dip. You must be aware that these trees like a damp climate. Temperature and humidity are the most important factors in rambutan growth.
The seedling can be used to establish a rambutan tree. If available, you can obtain seedlings from a nearby nursery. If you have access to the fruit, you may generally pick the seeds straight from the Rambutan tree. You need to locate viable seeds that are less than one week old. The pulp must next be separated from the seed.
Prepare many small containers or pots with drainage holes. Then, fill each one with the organic soil, compost, and sand mixture. Cover the seeds with dirt and plant them in the mixture. In general, it will take the seeds around 21 days to germinate. Typically, it takes at least two years for rambutan trees to become large enough for outside planting.
If the graft is successful, the knot is removed after 20 to 25 days and the rootstock is chopped down. There are between 100 (10 x 10 m) and 285 (5 x 7 m) trees planted per hectare. The plant is quite resilient and requires no special care beyond annual maintenance trimming (removing dead branches).
Approximately five to six years are required for seed-grown rambutans to bear fruit, but grafted or layered trees begin bearing fruit after three years. To guarantee high output, it is ideal to establish a mixture of kinds within the orchard, as well as a few male trees, to promote insect-pollination.
Despite these safeguards, recorded yields in Asia range from 2 to 20 tonnes of fruit per hectare. In certain places, such as Thailand, growth regulator sprays are used to stimulate the formation of functionally male flowers inside inflorescences. The rambutan is susceptible to several bioaggressors.
- It is particularly susceptible to powdery mildew during blooming and fruit set.
- The fruits are infested with scale insects, mites, thrips, and even ants, which frequently cause lasting skin damage.
- Various fruit fly species (Ceratitis capitata and Bactrocera dorsalis) are also found on rambutans, necessitating the use of particular treatments when shipping fruit from a contaminated location to an uncontaminated one.

Is it simple to cultivate rambutan?
How to Grow Rambutan From Seed – Growing a rambutan from seed is straightforward, but it may take the seedlings five to six years or more to yield fruit. From a mature rambutan fruit, remove the elongated, light brown seed. The fruit’s flesh and fluids impede germination, therefore carefully wash the seed before attempting to germinate it.
- Plant the seed in a small plastic nursery pot with drainage holes at the bottom.
- The University of New Hampshire Extension suggests using 4 quarts of shredded peat moss or coconut coir, 4 quarts of vermiculite, 1 tablespoon of superphosphate, and 2 teaspoons of crushed limestone to create a soilless seed-starting mix.
Sow the seed horizontally with the flat side pushed into the developing mixture’s surface. Lightly cover the seed with wet growth medium. Place the container in a light area above a seed-starting mat heated to 75 degrees Fahrenheit, and maintain a wet soil.
