Does the trunk of a rose grafted on a China rose tree thicken every year?
The trunk of a rose grafted on a China rose tree generally does not thicken. This is because the rootstock has already been shaped, and it is difficult to grow larger. Therefore, it is usually necessary to select rootstock with a diameter of 3 centimeters or more for grafting to prevent the top-heavy situation. Additionally, leaving a bud of the rootstock higher up during grafting can also make the stem thicker, although its own growth rate might be slower than that of the scion.
