How to Grow Mango Tree from Cutting by Onion

Steps to Attempt Growing a Mango Tree from Cutting Using Onion:

1. Prepare the Onion:

   • Peel the onion and cut it in half or into several thick slices.
   • Some methods suggest making a small hole in the center of an onion slice or mashing the onion to extract its juice.

2. Prepare the Mango Cutting:

   • Take a healthy, semi-hardwood cutting about 6-12 inches long.
   • Remove all leaves from the lower 2-4 inches of the cutting.
   • Make a fresh, angled cut at the bottom of the cutting.
   • You can also make a few shallow vertical slits on the bark of the bottom inch of the cutting to expose more cambium (the growing layer).

3. Apply Onion to the Cutting:

   • Method 1 (Direct Insertion): Insert the bottom of the mango cutting directly into a thick slice of onion. Ensure the cut end is firmly embedded in the onion.
   • Method 2 (Onion Juice/Slurry): Dip the prepared end of the cutting into fresh onion juice or a slurry made from mashed onion. Let it soak for a few minutes.

4. Plant the Cutting:

   • Fill your pot with the well-draining potting mix.
   • Make a hole in the center of the potting mix.
   • Carefully insert the mango cutting (with or without the onion slice still attached, depending on your chosen method) into the potting mix.
   • Gently firm the soil around the base of the cutting to ensure good contact.

5. Create a Humid Environment:

   • Water the potting mix thoroughly.
   • Cover the pot and cutting with a clear plastic bag or a clear plastic dome to create a mini-greenhouse effect. This helps maintain high humidity, which is crucial for rooting. Ensure the plastic doesn’t touch the leaves if possible.
   • You can use sticks or wires to support the plastic bag above the cutting.

6. Provide Ideal Conditions:

   • Place the pot in a warm location with indirect sunlight. Avoid direct, scorching sun.
   • Maintain consistent moisture in the potting mix, but avoid overwatering, which can lead to rot. Check the soil daily and water as needed.
   • Periodically open the plastic covering for a few minutes to allow for air circulation and prevent fungal growth.

7. Patience is Key:

   • Rooting mango cuttings can take several weeks to several months, and success is not guaranteed.
   • You’ll know the cutting has rooted when you see new leaf growth. Gently tugging on the cutting (very gently!) and feeling resistance can also indicate root formation.
   • Once rooted, gradually acclimate the plant to lower humidity before transplanting.
