When To Graft Avocado Tree


Avocados are some of the most popular, nutritious and profitable crops in the world. The humble trees provide countless varieties of an abundant, delicious fruit and are valued for their healthy properties and flavor. One of the most important steps for the growth and fruiting of an avocado tree is grafting, the process of attaching and uniting the genetic material of two or more compatible plants. In this article, we will explain when to graft an avocado tree in order to get the most out of its potential.

Why Graft Avocado Trees?

Grafting avocado trees is a fundamental part of the agricultural process. Its importance is due to the fact that the timing of grafting has a direct impact on the development, flowering and, ultimately, fruiting of the tree. If done properly and at the ideal moment, grafts will produce a hybrid tree that is resistant to diseases and climate variations, has stronger and healthier root systems, as well as higher yields and greater yields of better quality fruits.

When Should Avocado Trees Be Grafted?

When it comes to the decision of when to graft an avocado tree, there is no universally-valid answer. However, what is certain is that the decision must be made depending on the age of the tree and the relative climates, soils and topography of the place where the tree is located. Generally, the best time to graft an avocado tree is before the new growth starts in the early spring, as grafting before then ensures more effective results.

How to Prepare the Avocado Tree for Grafting?

In order to ensure the most successful grafting process and results, there are certain steps that must be taken in the preparation of the avocado tree. After a grafting window has been determined, the tree must be prepared for the surgery. This means that the trunk has to be hardened and rid of encroaching roots, branches and shoots to ensure that the tree is strong enough to receive and absorb the new grafts. Additionally, the tree must be pruned to create an even and balanced canopy that can provide the grafts with ample exposure to sunlight and rain.

The Grafting Process

Once the tree has been adequately prepared and the grafting window determined, the actual process of grafting can begin. The first step is to obtain the necessary parts: either buy or cut the select branches that have mature brown bark, known as ‘graftwood.’ Then, they must be freshly cut, with a small heel of healthy tissue and put in a bucket of cold water until ready for use. On the avocado tree, a few thick and hard branches must be selected to serve as donors and one of the V-shaped notches made to accommodate the new grafts. The chosen pieces of graftwood then have to be inserted in those notches and wrapped securely with tape. Finally, careful pruning must be done to ensure that the grafts stand in harmony with the rest of the tree.

After Grafting

After the grafting is done, new shoots will start to appear shortly and the tree is ready to develop. The grafts have to be checked regularly to make sure that they are growing properly and the tree must be constantly monitored and cared for to ensure the best conditions for their development. With enough supervision and adequate nourishment, the tree should start to attain its maximum potential within a few months, providing a rich supply of avocados for many years.


Besides the exact timing of the grafting, the environment of the avocado tree is probably the most influential factor for its growth and fruiting. The soil and the climate of the region must be studied accordingly to determine the best fit for the tree’s characteristics. Depending on these conditions, grafting an avocado tree may need to be done a few months earlier or later than usual.

Other Considerations

Other factors such as the availability of specific nutrients in the soil, the placement of the tree in relation to sunlight, the quality of air, access to water and the competence of external employees must also be considered and attended accordingly to ensure a successful introduction of the tree into its environment.

Types of Grafts

When it comes to the selection of the graftwood, there are several grafting types available. The most common ones are the Crown Graft, where a branch of the desired variety is cut just below a node, inserted into the stem of the rootstock, and the side graft, where a long stem of the desired variety is inserted onto the side of the rootstock. Other methods include bark grafting, cleft grafting and whip grafting, each with its own advantages and disadvantages.

Care and Maintenance

After the grafts have been inserted, caring for and maintaining the avocado tree is essential for the final results. Correct pruning and watering techniques must be employed, in addition to the regular monitoring of the tree’s health. Regular inspection and analysis of the tree by qualified professionals is also recommended, in order to detect any underlying problems that may arise during the process of growth.


Grafting an avocado tree is a delicate process that requires careful consideration and precision. With knowledge in the field of grafting, an appropriate selection of the best graftwood and meticulous care, you can expect amazing results in the shape of a fruitful and healthy avocado tree.
