Avocados are a beloved fruit, packed with healthy fats, and prized for their creamy texture and flavor. While growing an avocado tree from seed is a common method, it takes much longer for the tree to bear fruit. On the other hand, cultivating avocado trees from cuttings is a more efficient and reliable method for growing an avocado tree that will fruit faster and with better results. In this guide, we’ll walk you through the entire process of growing an avocado tree from a cutting—helping you achieve success with this rewarding gardening project!
Why Grow an Avocado Tree from Cuttings?
Growing an avocado tree from a cutting offers several advantages over starting from seed:
- Faster Fruiting: When you propagate an avocado tree from a cutting, the tree has a head start and typically produces fruit sooner than a seed-grown tree, which can take 13 years or more to fruit.
- Genetic Consistency: By taking a cutting from a healthy, productive avocado tree, the offspring will be genetically identical to the parent tree. This increases the likelihood of having a strong, fruitful tree.
- Better Control Over Tree Size: Starting with a cutting allows for more control over the tree’s size and shape. This is especially important if you’re growing avocado trees in containers or small spaces.
What You’ll Need
Before you begin, make sure you have all the necessary supplies for growing an avocado tree from cuttings. Here’s a list of what you’ll need:
- A healthy, mature avocado tree (preferably a tree that is already producing fruit)
- Sharp, clean pruning shears or scissors
- Rooting hormone (optional but recommended)
- Well-draining potting mix
- A small pot or container with drainage holes
- A clear plastic bag or plastic wrap (for creating a humid environment)
- A warm, sunny spot with indirect light (or grow lights if indoors)
Step 1: Select a Healthy Cutting
The first step in growing an avocado tree from a cutting is selecting the right branch. Choose a branch that is healthy, mature, and has no signs of disease or damage. The cutting should be at least 15–20 cm (6–8 inches) long. Make sure the cutting has at least 3–4 healthy leaves and one or two buds. The cutting should come from the middle of the tree, not from the very tip, as this ensures the cutting has enough nutrients and energy for root development.
Step 2: Trim the Cutting
Using sharp and clean pruning shears or scissors, trim the cutting from the selected branch. Cut the branch at a slight angle just below a node (where the leaf attaches to the stem). This will help the cutting to absorb moisture and nutrients more effectively. Remove any leaves from the lower part of the cutting, leaving only the top few leaves intact. This ensures that the cutting focuses its energy on root growth rather than trying to support too many leaves.
Step 3: Apply Rooting Hormone (Optional)
To increase your chances of successful rooting, you can dip the cut end of the avocado cutting into rooting hormone. Rooting hormones contain plant growth hormones that stimulate root development. While this step is optional, it can significantly improve your chances of success, especially if you’re a beginner.
Dip the cut end into the rooting hormone powder and gently tap off any excess. Avoid applying the hormone to the leaves or the rest of the cutting, as it’s only meant for the cut end.
Step 4: Prepare the Pot and Soil
Avocado trees require well-draining soil to thrive, so it’s important to choose a pot with drainage holes and a well-draining potting mix. You can use a cactus or succulent mix, or mix your own by combining equal parts of perlite, sand, and peat moss. This will ensure that the soil doesn’t hold too much moisture, which could lead to root rot.
Fill the pot with the potting mix, leaving about 2-3 cm (1 inch) of space from the top. Make a small hole in the center of the soil with your finger or a pencil, large enough to fit the base of the cutting.
Step 5: Plant the Cutting
Gently insert the cut end of the avocado cutting into the hole in the soil. Press the soil around the base of the cutting to secure it in place. Be sure that the cutting is planted deeply enough to stand upright but not too deep that it suffocates. The cutting should sit firmly but still have room to develop roots.
Water the soil lightly, ensuring that it is moist but not waterlogged. You want to keep the soil consistently moist, but too much water can cause the cutting to rot.
Step 6: Create a Humid Environment
Avocado cuttings need a humid environment to encourage rooting. To maintain humidity around the cutting, cover the pot with a clear plastic bag or wrap it with plastic wrap. The plastic will trap moisture, creating a mini greenhouse effect. However, be sure to leave a small opening for ventilation to avoid mold buildup.
Alternatively, if you’re growing the cutting indoors, you can place the pot in a humidity dome or use a propagator to keep the humidity levels high. Make sure to check the cutting regularly to ensure it’s not getting too hot or too wet.
Step 7: Provide Proper Light and Temperature
Place the pot in a warm, sunny spot with indirect light. Avocado trees thrive in temperatures between 60–85°F (15–29°C), so try to keep the cutting in a room that maintains this temperature range. Avoid direct sunlight, as it can scorch the cutting or dry it out too quickly.
If you’re growing the cutting indoors and natural sunlight is insufficient, you can use grow lights to provide the necessary light for healthy root growth. Make sure to keep the light on for 12–16 hours per day, as avocado trees need a lot of light to grow well.
Step 8: Wait for Root Development
After 4–6 weeks, your avocado cutting should begin to develop roots. Gently tug on the cutting to see if there is resistance, which indicates that roots are forming. You can also check the base of the cutting for visible root growth. During this time, keep the soil lightly moist but not soggy, and continue to provide indirect light and warmth.
Once the cutting has established roots and is growing new leaves, you can begin to gradually acclimate it to less humidity by removing the plastic cover for short periods of time, increasing the exposure each day.
Step 9: Transplant and Care for the New Avocado Tree
When your avocado cutting has developed a strong root system and is showing signs of healthy growth (such as new leaves), it’s time to transplant it into a larger pot or directly into the ground if you’re growing it outdoors.
To transplant the cutting, gently remove it from its current pot and place it in a larger pot with fresh, well-draining soil. Continue to care for it by watering regularly, fertilizing every few months with a balanced fertilizer, and ensuring it receives plenty of indirect light.
Step 10: Be Patient and Enjoy the Journey
Avocado trees typically take 3–4 years to bear fruit, so be patient as your tree matures. Prune the tree regularly to maintain its shape and encourage branching. With time, care, and attention, your avocado tree will grow into a healthy, fruit-bearing plant that provides you with delicious avocados year after year.
Conclusion
Growing an avocado tree from a cutting is a satisfying and rewarding experience. With the right materials, care, and attention to detail, you can propagate your own avocado tree that will eventually produce fruit faster than a seed-grown tree. By following the step-by-step guide outlined in this article, you can ensure the success of your avocado cutting and look forward to enjoying homegrown avocados in the future. Happy gardening!
