What Is Micro Budding?

Micro-budding is a grafting technique used in the development of citrus trees. Like traditional grafting, there is a combination the hardy characteristics of a rootstock with the desired fruit of the budded region; however, micro-budding is done at a younger age, and because of apical hormonal dominance, the resulting citrus trees grow faster and bear fruit at an earlier stage (2 years) than traditional T-budded grafted trees (5 years to fruit)

Micro-budding is an all-natural, non-GMO process of grafting by hand which produce lemon trees, lime trees, orange trees, mandarin trees, kumquat trees and grapefruit trees that bear fruit earlier and grow faster with routine care

A smaller micro-budded tree has incredible root growth when planted in a large container, resulting in a quicker output of fruit and growth.

US Citrus is the proprietary producer of micro-budded citrus trees, all of our 12 varieties of flowering citrus trees are available online in our citrus tree store. 

This makes it possible to give citrus trees as a wonderful gift tree, to have beautiful, ornamental flowering trees in your patio. The smell of citrus flowers is incredible, (pink flowering trees available with the pink variegated lemon tree. 


Grafting is an ancient process, combining the strong and vigorous qualities of a rootstock with the desired qualities of the bud that is being grafted onto that rootstock. Micro-budding is a relatively new process of about 20 years, while grafting is an ancient process.


A rootstockis a part of a plant which has very hardy qualities. Example rootstock qualities include withstanding disease, resisting heat and drought or frost. Grafting is used across multiple types of fruit trees, and it is the standard process for citrus.

Without grafting, there are very inconsistent results on whether a tree would bear good fruit. This is like humans having children, the offspring can be quite different from the parents. In this manner, the genetics of the seed from a fruit tree may not be exactly that of the fruit tree.

So you may have a Mandrain – take a seed from an orange borne of that tree, and if you plant that seed, its fruit may have different characteristics (not as sweet or juicy, different color). Instead, with grafting, an actual piece of the mother tree is used, so that an actual clone of that tree is produced.

These two parts will become one tree, growing together while having and taking the best qualities of both the rootstock and the grafted bud. This process is so ancient, that it is even described in the New Testament. And because the graft is an actual physical portion of the old tree instead of its seed, it is like getting a clone of that tree. So, if you find a great mother tree which produces perfect lemons of great sour characteristic, nice color, and plenty of juice, you want all those characteristics to remain consistent.

Micro-budding involves the same principles of grafting; however, is done at a much younger age, when the trees are weeks old, instead of typically 18 months. This process is done entirely by hand and involves a very specialized care regimen, which is done solely at US citrus nurseries.

Because of the physiology of the micro-budded citrus tree, with the cuts being done in small areas and resulting apical dominance of the hormonal system and the fact that this is not a very young age, the trees respond prolifically. They bear fruit much faster and grow much quicker than conventionally grafted citrus trees , with much stronger root systems it seems once implanted into their final container or into the ground.
