Different Types Of Cuttings That Can Benefit From Rooting Hormone

Rooting hormone is commonly used on ornamental plants and succulents, but it can be beneficial for a variety of different plant species. Stem cuttings are the most commonly propagated type of cutting, and they can be easily treated with rooting hormone.

Leaf cuttings, which involve taking a leaf from a parent plant and encouraging it to form roots, can also benefit from the use of rooting hormone. By applying the hormone to the part of the leaf closest to the center of the plant and covering it with potting mix, gardeners can increase the chances of successful propagation.

Root cuttings, taken in the fall for new plant production in the spring, can also benefit from rooting hormone. By treating the cut ends of root cuttings with rooting hormone, gardeners can improve the chances of successful root development and establishment.

Choosing The Right Rooting Hormone Form And Concentration

When choosing a rooting hormone, gardeners have the option of selecting between powder, gel, and liquid forms. Each form has its own advantages, making them suitable for different situations.

  • Powder rooting hormones: These are easy to use and can be dusted onto the cut end of a stem or leaf.
  • Gel rooting hormones: They provide a thicker consistency, which helps them adhere to the cutting more effectively.
  • Liquid rooting hormones: These can be applied to the cutting by dipping or soaking.

The choice of rooting hormone concentration depends on the type of cutting being propagated.

  • Low concentrations of rooting hormones are typically used for herbaceous softwood cuttings taken in summer.
  • High concentrations are used for woody hardwood cuttings taken in winter.

Step-By-Step Guide For Using Rooting Hormone On Stem Cuttings

To use rooting hormone on stem cuttings, begin by selecting a fresh, healthy stem from the parent plant. Cut just below a node, which is where the leaves emerge from the stem. It is important to remove any leaves or flowers from the area near the node.

Before applying the rooting hormone, moisten the bottom few inches of the cutting. This helps the hormone adhere to the cutting more effectively. Then, dip the bottom of the cutting into the rooting hormone, making sure to coat the entire cut end.

Once the cutting is adequately coated in rooting hormone, it can be planted in a soilless potting medium. Before planting, it is recommended to shake off any excess powder from the stem cuttings to avoid any potential issues. When planting the cutting, make a wide planting hole to prevent rubbing off the rooting hormone.

After planting, water the cutting lightly and keep it warm – away from direct sunlight. It is important to provide a humid environment for the cuttings by covering them with a plastic bag or propagator lid. This helps to maintain moisture levels and creates a favorable environment for root development.

Tips for using rooting hormone on stem cuttings:

  • Select a fresh, healthy stem from the parent plant
  • Cut just below a node, removing any leaves or flowers near the node
