How To Grow A Rambutan Tree: Step By Step
Step 1: Consider Your Environment
Before growing a rambutan tree, consider the environmental conditions they need to thrive. If you aren’t located in an area that meets these requirements, ensure you have a greenhouse. Rambutan trees need a hot, humid location.
Step 2: Use Fresh Seeds – How To Grow A Rambutan Tree
Old seeds won’t grow. Order new seeds online or get one from fresh fruit.
Step 3: Prepare The Seed And Soil
You’ll need a clean, dry seed for planting. Wash the fleshy parts from your rambutan seed and pat it dry.
Mix organic soil and compost with sand and fill a pot with it.
Step 4: Planting Your Seed
Ensure that your container has good drainage before planting your rambutan seed. You should plant the seed horizontally with its flat side. If you do this, the tree roots will grow straight to create strong and healthy roots.
Step 5: Care For Your Seed
Germination can take up to 21 days. Your rambutan will then need to grow for about 2 years before you can replant it into a bigger container.
Give your rambutan tree water as soon as the soil feels dry and ensure it’s in a sunny spot. Rambutan trees are sensitive to drought, especially during the first dry season. Keep your tree well moisturized to prevent growth issues.
You should control any weeds appearing next to your tree. You should also prune dead twigs and water shoots.
Step 6: Replant The Tree – How To Grow A Rambutan Tree
Once your rambutan tree is about a foot tall, you can replant it into a ceramic pot. Don’t attempt to plant it directly into the ground – the rambutan tree will still be fragile at this point.
Use a mix of vermiculture, sand, and peat to ensure excellent drainage.
Fertilize your rambutan tree every 6 months after replanting. You should look for fertilizers that contain urea, potash, and phosphate.
