7 Water the plant regularly and fertilize it monthly.
8 The plant will produce fruit in 3-4 years.

Choosing the Right Seeds

When choosing rambutan seeds, it is important to select seeds that are healthy and viable. Here are a few things to look for when choosing seeds:

  • Size: The seeds should be about the size of a small pea.
  • Color: The seeds should be a light brown color.
  • Texture: The seeds should feel smooth and firm.
  • Shape: The seeds should be oval-shaped.
  • Germination rate: The germination rate of the seeds should be high.

You can test the germination rate of the seeds by placing them in a bowl of water. The seeds that sink to the bottom of the bowl are viable, while the seeds that float to the top are not.

Once you have selected the right seeds, you can prepare them for planting. To do this, you will need to:

  • Soak the seeds in water for 24 hours.
  • Remove the seeds from the water and dry them thoroughly.
  • Score the seeds with a sharp knife.
  • Place the seeds in a moistened paper towel and seal the paper towel in a plastic bag.
  • Place the bag in a warm place (such as a sunny windowsill) and wait for the seeds to germinate.

The seeds will germinate in about 2-4 weeks. Once the seeds have germinated, you can transplant them into pots or seedling trays filled with potting soil.


Once you have germinated the rambutan seeds, you will need to care for the seedlings until they are large enough to transplant into the ground. Here are a few tips for caring for rambutan seedlings:

  • Water the seedlings regularly. The seedlings need to be watered regularly to keep the soil moist. However, you should avoid overwatering the seedlings, as this can lead to root rot.
  • Provide the seedlings with bright light. Rambutan seedlings need bright light to grow properly. Place the seedlings in a sunny spot or under a grow light.
  • Fertilize the seedlings monthly. Use a diluted fertilizer that is high in nitrogen and phosphorus.
  • Pest-proof the seedlings. Rambutan seedlings are susceptible to pests, such as aphids and mealybugs. Inspect the seedlings regularly and treat them for pests if necessary.

The seedlings will be ready to transplant into the ground when they are about 6-8 inches tall. To transplant the seedlings, you will need to:

  • Dig a hole in the ground that is twice the size of the seedling’s root ball.
  • Carefully remove the seedling from the pot or seedling tray.
  • Place the seedling in the hole and fill the hole with soil.
  • Water the seedling thoroughly.

The seedlings will need to be watered regularly and fertilized monthly. They will also need to be protected from pests. With proper care, the seedlings will grow into healthy rambutan trees.

Growing rambutan from seed indoors is a fun and rewarding project. With a little patience and care, you can grow your own rambutan trees at home.

Here are a few tips for successful rambutan tree growth:
