Mango Tree Propagation: A Comprehensive Guide to Grafting

Introduction

Growing mango trees is a rewarding experience, and one of the most reliable methods of propagation is through grafting. Grafting involves combining a piece of a mature, fruit-bearing tree (scion) with a separate seedling (rootstock). The scion becomes the canopy of the tree, while the rootstock forms the lower trunk and root system.

Benefits of Grafting Mango Trees

• Faster fruiting: Grafted mango trees begin bearing fruit sooner than trees grown from seed.
• Improved fruit quality: Grafting allows you to select scions from trees with desirable fruit characteristics, such as size, shape, and sweetness.
• Disease resistance: Grafting can help introduce disease resistance into your mango trees.
• Space efficiency: Grafting allows you to grow multiple varieties of mango trees in a smaller space.

Choosing the Right Rootstock

The choice of rootstock is crucial for successful grafting. Some recommended rootstocks for mango trees include:

• Kensington
• Common mango
• Turpentine (in South Florida)

The rootstock should be vigorous, free from disease, and about 6 months to one year old.

Preparing the Rootstock and Scion

1. Cut the rootstock: Using sharp pruning shears, cut the chosen seedling stem about 4 inches above the soil. The stem should be between 3/8 and 1 inch across and have healthy leaves and buds.
2. Split the stem: Use a knife to split the remaining stem in half from top to bottom, about an inch above the soil’s surface.
3. Select the scion: Choose a new growth shoot from an existing mango tree. The scion should have fresh buds and leaves, and its thickness should be equal to or slightly smaller than the rootstock.
4. Cut the scion: Cut a 3 to 6-inch piece of the scion from the tree and trim back the uppermost leaves.
5. Prepare the scion: Make a wedge in the cut end of the scion and slice the bark away along each side to create an angled point.

Performing the Graft

1. Insert the scion: Place the scion wedge into the slot you’ve cut in the rootstock, making sure they line up.
2. Secure the graft: Use grafting tape to wrap around the rootstock and scion to secure them together.
3. Protect the graft: Put a plastic bag over the new graft and tie it off at the bottom to create a warm, humid environment and protect it from insects and pests.

Aftercare

1. Remove the bag: Once the tree has begun growing, remove the plastic bag.
2. Remove the tape: Remove the grafting tape once the tree produces new leaves.
3. Water the tree: Water the tree regularly, but avoid overwatering.
4. Prune out suckers: Suckers are shoots that may grow from the rootstock below the graft union. These should be pruned out to prevent them from competing with the grafted scion.

Troubleshooting

• The graft is not taking: Check if the rootstock and scion are properly aligned and secured. Ensure that the graft union is kept moist and protected from pests.
• The tree is not growing: Make sure the tree is getting enough sunlight, water, and nutrients. Check for signs of disease or pests.
• The fruit is not of good quality: The fruit quality may be affected by the variety of scion used, as well as the growing conditions.

Conclusion

Grafting is a valuable technique for propagating mango trees that offers numerous benefits. By following the steps outlined in this guide, you can successfully graft mango trees and enjoy the fruits of your labor.
