How to Propagate Avocado Trees Using Young Shoots and Natural Methods

Avocado trees are among the most rewarding fruit trees to grow at home, offering nutritious fruits and a lush green canopy. While growing avocados from seed is a common method, it’s often slow and unpredictable. An alternative and faster way to multiply avocado trees is through propagation using young shoots. This method allows gardeners to clone existing trees, preserving desirable traits like fruit quality and disease resistance.

In this guide, you’ll learn how to propagate avocado trees using young shoots, red onion as a natural treatment, and simple materials like sand and water. This method is ideal for home gardeners seeking a natural and low-cost approach to avocado propagation.


Step 1: Select Young Avocado Shoots

Begin by selecting healthy, young shoots from an existing avocado tree. These should be green, flexible, and free from disease or insect damage. Shoots that are too old or woody tend to root poorly, while very tender growth may wilt easily.

Using clean pruning shears or a sharp knife, cut the shoots into pieces about 5 to 7 centimeters long. Each cutting should ideally have at least one leaf or a leaf node — this is where roots will likely emerge. If the cutting has more than two leaves, gently remove the excess to reduce water loss and focus the plant’s energy on root development.


Step 2: Use Red Onion as a Natural Antibacterial Agent

To prevent infections and stimulate healthy growth, red onion can be used as a natural antibacterial treatment for the cuttings. Red onions are rich in sulfur compounds and antioxidants that help combat bacterial and fungal pathogens.

Here’s how to apply it:

  1. Peel and crush a few slices of red onion.
  2. Place the crushed onion in a bowl with a small amount of clean water.
  3. Let the cuttings soak in this mixture for 10–15 minutes.

This simple treatment helps disinfect the cut surfaces of the avocado shoots and may also provide a mild rooting boost thanks to the plant compounds found in onions.


Step 3: Prepare the Planting Medium with Sand

For the best results, use a light and well-draining medium to root the avocado cuttings. Sand — particularly river or coarse sand — works well. It retains moisture without becoming waterlogged and offers excellent aeration, both of which are essential for root formation.

Fill small pots or seedling trays with clean sand. If available, you can mix in a small amount of compost or cocopeat to add nutrients and improve water retention slightly, but pure sand also works effectively.

Before planting, moisten the sand thoroughly. It should be damp but not soggy.


Step 4: Plant the Cuttings

Take each treated avocado cutting and insert the lower end about 2 to 3 centimeters deep into the prepared sand. Firm the sand around the base to ensure stability and support.

Be sure not to overcrowd the cuttings — give each one enough space for air circulation and light exposure.


Step 5: Provide Shade and Consistent Watering

Place the potted cuttings in a shaded area with good airflow. Avoid direct sunlight at this stage, as it can cause the young cuttings to dry out or become stressed. A partially covered area like a greenhouse, porch, or under a tree canopy is ideal.

Water the cuttings gently but consistently. The sand should remain moist throughout the rooting period. Typically, watering once or twice a day — especially during dry weather — is sufficient. Be cautious not to overwater, as standing water can cause rot.


Step 6: Monitor Progress and Root Development

Over the next few weeks, monitor the cuttings for signs of growth. New leaf buds or increased firmness in the stem are indicators that rooting is underway. Root development usually takes 3 to 6 weeks, depending on temperature, humidity, and shoot quality.

To check for root development without disturbing the plant too much, gently tug on a cutting after about a month. If it resists being pulled up, roots have likely formed.


Transplanting and Aftercare

Once the cuttings have developed strong roots, they can be transplanted into larger pots or directly into garden soil. Choose a well-draining, fertile spot with good sunlight. During the early transplant period, continue to water regularly and protect the young trees from harsh sun or wind.

After a few months of proper care, the new avocado trees will begin to establish themselves and grow steadily. This propagation method not only saves time but also allows gardeners to produce multiple clones of high-quality avocado trees without the need for advanced tools or expensive rooting hormones.


With just a few young shoots, some red onion, and simple materials like sand and water, you can propagate avocado trees naturally and effectively. This technique is ideal for home gardeners looking to expand their orchard in an eco-friendly and efficient way.

Give this method a try, and you may soon be rewarded with a thriving grove of healthy, homegrown avocado trees.
