A well-chosen cutting will exhibit a strong, vigorous stem section, with a balanced distribution of foliage and a well-developed root system.

Cuttings with a diameter of 1-3 inches (2.5-7.5 cm) tend to root more successfully than thinner or thicker sections.

A length of 6-12 inches (15-30 cm) provides sufficient material for rooting and subsequent pruning.

Cuttings with a gentle, tapering shape often develop stronger roots than those with abrupt or angular cuts.

Avoid taking cuttings from weak or damaged areas, as these may struggle to establish themselves.

Bear in mind the species' natural branching patterns when selecting cutting material, as this can influence the development of the new plant's structure.

Stem and Leaf Selection

Most bonsai enthusiasts agree that selecting cutting material with the right balance of stem and leaf characteristics is crucial for successful propagation.

The ideal stem should be around 1-3 inches in length, with a diameter of approximately 1/4 inch, and exhibit a subtle taper from base to tip. This guarantees a suitable balance between stem strength and rooting potential.

With regard to leaf selection, it is essential to choose cuttings with healthy, mature leaves that are neither too old nor too young. Leaves should be a vibrant green color, with no signs of disease, pests, or nutrient deficiencies.

A good rule of thumb is to select leaves that are roughly one-third to one-half the size of the mature leaf. This allows for ideal energy allocation during the rooting process.

Freshness and Health

In order to guarantee ideal rooting and establishment, it is essential to select cutting material that exhibits not only the right balance of stem and leaf characteristics but also superior freshness and health.

This certifies that the cutting is more likely to overcome the stress of being severed from the parent tree and adapt to its new environment.

Fresh cutting material is characterized by vibrant, healthy foliage, supple stems, and a well-developed root system.

Some key indicators of freshness and health include:

  • Plump, hydrated leaves with a natural sheen
  • Stems with a slight flexibility and a subtle woody aroma
  • A well-developed root system with white, fibrous roots
  • Minimal signs of pests, diseases, or physical damage
  • A general appearance of liveliness and vigor

Preparing Cuttings for Propagation

As we shift from selecting the ideal cutting material to preparing cuttings for propagation, it is essential to establish a solid foundation for successful rooting.

This involves carefully evaluating each cutting against specific selection criteria, such as freshness, health, and rooting potential, to guarantee only the most promising specimens are used.

Cutting Selection Criteria

When selecting cutting material, it is essential to prioritize branches with vigorous growth, as they typically exhibit a higher propensity for root development and increased resilience to the stress of being severed from the parent tree.

These branches often display characteristics that indicate their suitability for propagation, such as:

Plump, healthy buds that are rich in stored energy

A smooth, unblemished bark that is free from signs of disease or pests

A sturdy, well-developed node that will provide a strong anchor for new roots

A section of stem that is straight and free from twists or kinks

A cutting that is harvested during the dormant season, when the tree is less stressed and more receptive to propagation
