How to Clone Trees and Plants

Cloning plants and trees can be a fantastic way to propagate new garden specimens, preserve a cherished plant or tree or even produce large quantities of produce. Cloning is the process of creating a genetically identical copy of a plant or tree from a cutting, graft or division of an existing plant. Here are some methods for you to try:

Cloning by Stem Cuttings

The simplest and most common method of cloning is using stem cuttings. This process involves taking a portion of the stem and allowing it to grow new roots and leaves. The key to successful stem cutting is using a healthy and mature plant, taking the cutting at the right time of year and handling the new plant with care. Begin by selecting the right cutting – take a section of the stem with at least two nodes and a few leaves. Remove the lower leaves and dip the end in rooting hormone before planting it in well-drained soil. Keep your cutting in a warm and humid location and water regularly until it has established roots.

Cloning by Grafting

Grafting is another method utilized to clone trees and plants. This process involves taking a cutting from the desired plant and attaching it to the rootstock of a different plant. The key to successful grafting is to select compatible plants and make sure that the graft is secure. The process of grafting involves making a cut in the stem of the rootstock plant and inserting the stem of the cutting into the cut. The two stems should be securely bound together and then the graft site should be sealed with grafting wax to promote healing. The graft will take over and grow into a mature plant with characteristics of both the cutting and rootstock tree.

Cloning by Layering

Layering is the process of creating a new plant from an existing plant without taking a cutting. This process involves bending a flexible stem of the plant and inserting the tip underneath the ground while the parent plant is still in the soil. Once the stem is securely placed, it will begin to develop roots at the insertion point. When the roots are established, the stem is cut from the parent plant and is transplanted to a new location. Some varieties of plants are easier to layer than others – some plants that respond well to layering include raspberries, blackberries and roses.

Cloning by Division

This method is useful for plants that have multiple stems. Cloning by division involves dividing the plant and transplanting each section to create multiple new plants. Begin by separating the roots of the plant and gently dividing the stems or foliage. Each new plant should be potted in nutrient-rich soil and given adequate water and sunlight. Some plants are more tolerant of division than others – good candidates for division include hostas, irises, and daylilies.

Cloning trees and plants can be a rewarding and cost-effective way to propagate new plants, as well as preserve a particular tree or plant. By selecting the right method and handling the new plant with care, you can create a vast array of new gardening specimens that will bring joy and beauty to your garden for years to come.
