Rootstock

What Is Rootstock?

Rootstock refers to the lower portion of a plant, often a healthy and vigorous root system, onto which another plant, called the scion, is grafted. This horticultural technique enables gardeners to combine desired aboveground characteristics, such as fruit type or flower colour, with the beneficial traits of the rootstock, like disease resistance or adaptability to local soil. Using rootstock is especially common in fruit trees, roses, and some ornamentals.

Benefits of Using Rootstock in NZ Gardens

Selecting the right rootstock means more than just promoting strong roots. It can determine the size of your plant, its drought tolerance, and even its ability to resist certain pests and diseases. For instance, many citrus trees relied upon in New Zealand gardens are grafted onto specialized Citrus Rootstock to thrive in local conditions and maximise fruit yield. Rootstock can also help manage plant height, making harvesting and maintenance more accessible in smaller spaces.

Gardeners keen to introduce new varieties to their garden can find a wide range of live plants suitable for grafting or growing on established rootstock. Whether experimenting with apples, pears, or ornamental trees, making informed decisions about rootstock selection is key to long-term garden success.
