There are multiple ways for gardeners to grow new plants such as starting from scratch by planting seeds or bulbs. However, an other method is to take cuttings from an existing plant. This is often the simplest, cheapest and quickest way of doing it, especially if you are unable to source seeds or bulbs.

As the name suggests, a cutting is the process of cutting a stem from an existing plant. By placing the end of the stem in water, this encourages roots to grow which is essential for the survival of gardening plants. However, not all plants root easily, which is where the aid of rooting hormones come into play (chemicals designed to stimulate root growth from cuttings).

Sourcing the best rooting hormone isn’t difficult and the difference between products may not vary that much. However, there are some subtle differences, with some working better than others depending on your requirements.

Our Verdict

All the rooting hormones on this list do the intended job of protecting and boosting root growth from cuttings. Often it is not always the product at fault when the desired results fail to materialize, but rather the manner of which the product has been applied. For example, powdered products can be a little trickier to handle, which is why we recommend Clonex HydroDynamics Rooting Gel as the thick gel like product adheres to the stem for longer and there is no danger of inhaling chemicals as a result.

FAQ

Types of Rooting Hormones

You can purchase a root growth booster or you can make your own rooting hormone. Usually, the homemade plant root stimulator is gentler than the store-bought one, and you can control which substances you use as a growth hormone.

The substances that you can use to make your own rooting hormones can mostly be found in your kitchen, these include:
1. honey
2. willow water
3. apple cider vinegar
4. aspirin

You can later soak or dip the cuttings in the desired solutions.
Aloe vera is also a natural, homemade gel rooting hormone that has proven very powerful, while cinnamon makes for a great homemade rooting powder.

This natural homemade rooting hormone is just using powder cinnamon and dipping the previously moistened cutting in it.
All these substances contain one or another active ingredient that is useful to promote root growth, and most of them are extracted and found in store-bought varieties only in much higher concentrations. This is especially important if you are growing edible plants like fruits and vegetables.

To that account, read labels on the store-bought rooting hormones to make sure it is safe to use.
Rooting hormones come in a form of powders, gels, or liquids –  it does not matter if they are homemade or bought in a store.

Can you use Honey as a Rooting Hormone?

Honey is NOT suitable to use as a rooting hormone because it contains yeast spores that can contaminate your cuttings. It also often has bacteria in it too. If you want to use honey then please research what type is best and how to sterilize it before adding to your cuttings.

How to use Rooting Hormones?

Even if you chose the best root stimulator there is your plant will grow healthy only if you use the product correctly.

Depending on the substance you pick as your preferred rooting hormone and its type you can dip it directly in it, you can soak the cuttings before planting, or use the liquids to water the plants with it.

The most important thing is to read the instruction labels and follow them exactly as it says. Using less than the recommended dosage will likely fail the stem growing roots and seem like the product is not working.

On the other hand, if you use more than is recommended you will probably end up causing more damage than good as too many chemicals can kill the plant cuttings you want to propagate and multiply.
You can be a bit more flexible with homemade root stimulators since they are more gentle and some of them can really do no harm.
