About Grafted Plants
Grafting is a method of vegetative plant propagation that involves attaching scion wood from a desired plant variety to the rootstock of a related plant. Subsequently, the scion wood develops into the plant’s stem and branches, yielding the desired fruits. Notwithstanding, the roots and lower section of the stem remain from the original rootstock. This technique commonly imparts benefits such as drought resistance, dwarfing characteristics, or pest resistance. The grafted scion is typically chosen for its superior fruit size, flavour, colour, and shelf-life.
Importance of Removing Root Stocks Suckers
Rootstock always strives to create its own stem to replace the scion wood. As a result, it will generate suckers from the roots and lower portion of the stem, as these parts are more compatible with the roots and thus proliferate quickly. This process can occur within a month, potentially going unnoticed until the plant is entirely taken over. Once established, these suckers will divert water and nutrients from the grafted part of the tree. Consequently, the starved graft will eventually become stunted and die. This phenomenon leads grafted orange trees to bear lemons (rootstocks) or plum and apple trees to revert to producing small sour fruits. Therefore, the removal of rootstock suckers is essential. These can be planted and used to grow more rootstocks for grafting in the future.
Approach To Removing Root Stocks Suckers
The heat and rain over the past few weeks have triggered a surge in sucker development. It is crucial to mark the union site, as it could become less discernible over time. Make sure to diligently inspect grafted plants and promptly eliminate any suckers as soon as you spot them. We’ve even provided visual aids, including pictures and videos, to illustrate identifying and removing rootstock.
