Never heard of rooting hormones? Rooting hormone is used to help a plant to develop roots on a cutting so that it can be easily transplanted into soil. It is a synthetic hormone that helps create root-like structures ideal for a plant during the rooting process.

Gardeners use multiple methods for producing a plant identical to an existing plant, taking a cutting is usually the simplest way. Propagating by cutting is especially well suited to the indoor gardening plants that tend to grow well from cuttings. Even those who aren’t familiar with advanced gardening concepts and are just trying to clone a favorite plant from a planter can often be successful with cuttings.

Cuttings from some plants, such as ivy and Dieffenbachia, root easily in plain water. Others need a little encouragement, and that’s where rooting hormone comes in. Rooting hormones are chemicals that stimulate the growth of new roots on cuttings.

Finding the best rooting hormone is somewhat a matter of personal preference because most rooting hormone products are very similar. Read this article to better understand them and find the most suitable ones for your indoor gardening needs.

Frequently Asked Questions (FAQs)

What is the best rooting hormone?

Rooting hormones or rooting compounds are substances that promote root growth and help with the transplanting process. They are popular with indoor gardening and horticultural enthusiasts.

The best rooting hormone is Clonex Rooting Gel. As its name suggests, the Clonex Rooting Gel is neither a liquid nor a powder, but instead, a gel formulated to stick to the cutting’s stem. This gel has proven its worth, one of the most popular rooting hormones and often used in professional settings.

To use it, you’ll have to dip the cutting into the gel far enough to seal the cut, after which you can pot it up in your desired potting medium. The cutting will root in one or two weeks if the growing conditions are favorable, and the strong formula will provide nourishment in the root development stages.

You won’t need a lot of product for each cutting, which means a single 3.4 fl. oz. / 100 ml bottle will last you ages.

Do rooting hormones really work?

Yes, they do, if you use them according to the manufacturer’s instructions and this guide. Rooting hormones work well to propagate many types of houseplants, indoor trees, and succulents from a wide variety of cuttings, including leaves, stems, and roots.

How long does it take for a rooting hormone to work?

The rate of action is very dependent on the underlying plant. Some plants root within 1-2 weeks, and others can take several months.

Is there a substitute for rooting hormone?

Many people recommend apple cider vinegar or cinnamon as rooting hormones alternatives. However, since many gardeners use vinegar to kill weeds and garden pests, we recommend you do your homework thoroughly before attempting to use household products or spices as rooting hormones.

  • Use only a teaspoon of vinegar instead of a rooting hormone.
  • Pour a tablespoon of cinnamon on a paper towel, roll the sticky stem ends in that towel, and then plant the rolled paper and stems in a pot with potting soil.
  • Honey is a good bacteria killer, too. You can smear some honey directly on your cutting or, if you want, mix up a tea of 1 tbsp. (15 mL.) honey in 2 cups (480 mL.) boiling water. Cool the tea back down to room temperature before using it, and store it in a dark place.

We have never tried this, so we cannot vouch for such practices.


Gardeners use rooting hormones to stimulate buds and stems and various plants to start growing faster. While this guide specifically talks about rooting stems on plants like potatoes, the information about rooting hormones can apply to any plant for growing cuttings, as long as the product you choose is designed for your particular plants.
