Best Rooting Hormone for Cuttings: Eight Amazing Options for Your Garden in 2023

Patience is a virtue in the gardening world, yet it may only get you so far in rare instances. For example, you may find yourself grappling with a stubborn plant cutting that refuses to take root despite your best efforts.

But rather than throw in the towel and question whether you possess a green thumb, you might want to consider using a rooting hormone. These substances aid root development by helping the plant absorb much-needed nutrients from the planting medium.

So, if you’re looking for the best rooting hormone for cuttings in 2023, this guide has you covered. We discuss what they are, the factors to consider when choosing them, and more.

What Is a Rooting Hormone?

A rooting hormone is a substance that’s used to promote root development in plants. Aside from stimulating root growth, rooting hormones are commonly used for plant propagation, and some other rooting hormones go as far as aiding the plant’s overall health. Depending on the form it takes, a plant root hormone can help a wide range of plants and plant cutting types.

Rooting hormones fall into two main categories: natural and synthetic. Natural rooting hormones are either plant-derived substances (e.g., willow bark) or animal-derived (e.g., honey). In contrast, synthetic rooting hormones are lab-created substances formed through chemical processes (mainly Indole-3-butyric acid).

Types of Rooting Hormones

Gardening companies usually sell their rooting hormone brands in three forms: powder, gel, and liquid. Each has its pros and cons and is worth discussing to help you understand which suits your unique needs: 

Powder

Powder-based rooting hormones are among the most widely-available type of rooting hormone. They have long shelf lives, are easy to store, and are typically inexpensive.

When using a powdery rooting hormone, you’ll need to dampen your plant cutting before applying it. However, in rare cases, you won’t need any moisture at all (e.g., when coating seeds in the powder). 

The downside of using a powdery rooting hormone is that you have to be careful not to avoid contaminating your main batch. Preventing contamination entails using a separate container, which adds an extra step to what otherwise should be a straightforward task.

Gel

Gel rooting hormones are the easiest of the three types of rooting hormones to apply to plants. Their gelatinous consistency provides several advantages during plant propagation. 

First, it helps them seal the stem cutting. Second, this sealing quality ensures optical absorption of the rooting hormone. Third, you needn’t worry about contaminating your main batch, as you can dip the plant’s stem directly into the gel before planting it in the soil.

With that said, gardeners hesitate to purchase this rooting hormone type because, usually, they’re more expensive than their powder and liquid counterparts and require refrigeration.

Liquid

Liquid rooting hormones are ideal for hydroponics, a planting process that doesn’t always employ a soil-based substrate when providing nutrients to plants. The liquid is often highly concentrated, meaning you’ll need to dilute it before use. It’s best for particularly delicate plants, as it’s easy to absorb and seeps through the cutting’s smallest pores.

The disadvantage this rooting hormone poses is that it can spill if not handled carefully. Not only will such an incident result in waste, but it may also pose a slipping hazard to others. Additionally, difficult to dilute it the right way without following the instructions on the product label. This characteristic means it’s not as easy to use as the other two types.

Eight of the Best Rooting Hormones for Cuttings

Here are eight effective rooting hormones you can use in your home garden. Every one of them stimulates plant cuttings and is suitable for your propagation needs.

1. Garden Safe Take Root Rooting Hormone

Garden Safe rooting hormone for growing new plants from cuttings

Check Price on Amazon

Garden Safe has made products for gardening and pest control since 2002, and the brand’s Garden Safe Take Root Rooting Hormone is the cumulation of its years of experience.

This powder rooting hormone contains Indole-3-butyric acid, an active ingredient that shares similarities to the natural rooting hormone found in plants. It can stimulate root growth from cuttings and encourage root growth in new plants like African violets, philodendrons, roses, and so on. At 0.01%, the concentration of this ingredient isn’t high, though, which isn’t great.

It’s also easy to use: all you have to encourage growth from plant cuttings is moisten them (the cut end), stir in the powder, and plant after removing any excess rooting hormone. Therefore, you can do shock-free transplants while saving money through plant propagation.

Pros:

  • Garden Safe Take Root Rooting Hormone helps reduce transplant shock
  • Its active ingredient, Indole-3-butyric acid, is similar to natural plant hormones
  • This powdered rooting hormone is useful for several plant cuttings, including poinsettias, geraniums, and coleus

Dip'N Grow rooting solution induces root growth

Check Price on Amazon

Dip’N Grow DG01601 Rooting Solution Concentrate is a gel-based rooting hormone for propagating plants. It’s excellent for promoting root growth from plant cuttings and has been touted to be more effective than rooting powders. The formula contains the root auxins IBA and NAA, which help this rooting hormone to induce rooting.

As a liquid concentrate, you’ll have to dilute it in water to achieve the required strength necessary for root growth. Unfortunately, hitting the sweet spot can take numerous attempts, which isn’t something most gardeners would have the luxury of doing when their plants’ lives hang in the balance. 

The above notwithstanding, the concentrate promotes easy and even absorption of the rooting hormones into the plant’s cutting stem. It also contains alcohol, an ingredient that acts as a solvent for its active ingredients. Thus, this rooting hormone has self-sanitizing capabilities that keep cross-contamination issues in check.

Pros:

  • Its active ingredients help to promote root growth
  • Its concentrate helps plant root stems absorb the rooting hormone uniformly
  • The concentrate is shipped in bubble wrap and a plastic back to prevent spillage

Factors to Consider When Choosing a Rooting Hormone
