What is Rooting Hormone?

Rooting hormone is a substance that is used to stimulate root growth in plants. It is commonly used by gardeners and horticulturists to increase the success rate of plant propagation. Rooting hormone can be applied to cuttings, seeds, or even the roots of established plants to encourage the development of new roots. There are several different types of rooting hormone available on the market, each with its own unique properties and benefits.

Types of Rooting Hormone

There are three main types of rooting hormone: synthetic, natural, and homemade. Each type has its own advantages and disadvantages, and the choice of which one to use depends on the specific needs and preferences of the gardener.

Synthetic Rooting Hormone

Synthetic rooting hormone is a man-made substance that is designed to mimic the effects of naturally occurring plant hormones. It is typically available in powder, gel, or liquid form and is widely used by professional gardeners and commercial nurseries. Synthetic rooting hormone is known for its high success rate and fast-acting properties. It is particularly effective for difficult-to-root plants and can significantly increase the chances of successful propagation.

Synthetic rooting hormone works by providing the necessary hormones and nutrients that stimulate root growth. It contains a synthetic version of auxin, a plant hormone that is responsible for cell division and root development. By applying synthetic rooting hormone to cuttings or seeds, gardeners can ensure that the plants receive an adequate supply of auxin, which promotes the formation of new roots.

Natural Rooting Hormone

Natural rooting hormone, as the name suggests, is derived from natural sources such as plants, seaweed, or fungi. It is often available in powder or liquid form and is favored by organic gardeners who prefer to use natural products in their gardening practices. Natural rooting hormone is generally considered to be safer and more environmentally friendly than synthetic alternatives.

One of the main advantages of natural rooting hormone is that it contains a wide range of beneficial compounds, including vitamins, minerals, and amino acids, which can enhance overall plant health and vigor. These compounds not only stimulate root growth but also improve the plant’s ability to resist diseases and pests. Natural rooting hormone is also known for its gentle and gradual action, which can be beneficial for delicate or sensitive plants.

Homemade Rooting Hormone

Homemade rooting hormone is a cost-effective and sustainable alternative to synthetic or natural rooting hormone. It can be easily made using common household ingredients and is a popular choice among DIY gardeners. Homemade rooting hormone is typically made from substances such as willow bark, honey, cinnamon, or aloe vera.

The effectiveness of homemade rooting hormone may vary depending on the specific ingredients used and the method of preparation. However, many gardeners have reported successful results with homemade solutions. The advantage of using homemade rooting hormone is that it allows gardeners to have full control over the ingredients and avoid the use of potentially harmful chemicals.

How to Use Rooting Hormone

Regardless of the type of rooting hormone used, there are some general guidelines to follow when applying it to plants. First, it is important to choose healthy and disease-free plant material for propagation. This can include stem cuttings, leaf cuttings, or even root cuttings, depending on the plant species.

Next, the cuttings should be prepared by removing any leaves or flowers from the lower portion of the stem. This helps to redirect the plant’s energy towards root development. The cut end of the stem should then be dipped into the rooting hormone, ensuring that it is fully coated.

After applying the rooting hormone, the cutting should be planted in a suitable growing medium, such as a well-draining potting mix or a rooting tray filled with perlite or vermiculite. The cutting should be kept in a warm and humid environment, ideally under a plastic dome or in a propagator, to promote root growth.


In conclusion, rooting hormone is a valuable tool for gardeners and horticulturists looking to increase the success rate of plant propagation. Whether using synthetic, natural, or homemade rooting hormone, the key is to provide the necessary hormones and nutrients that stimulate root growth. By following proper application techniques and providing the right growing conditions, gardeners can greatly enhance the chances of successful root development and ultimately, the growth and vitality of their plants.
