How to use honey to promote root growth in cuttings
There are many synthetic rooting hormones available including liquids, powders and gels that can promote rapid root growth in cuttings, but if you’re an organic gardener or you’d just prefer a natural, chemical-free option, you should definitely consider honey as a natural rooting stimulant.

The reason honey works well as a natural rooting hormone is because it has anti-bacterial and anti-fungal properties.
Honey protects the cuttings from pathogens and allows the natural rooting hormones in the cutting to stimulate root growth.
Some plants will root well on their own without the need of rooting hormones, whereas other plants need a little help.
It’s rare to achieve a 100% success rate when propagating cuttings, but rooting hormones can help to increase your chances of success.
Honey vs Synthetic Rooting Hormones
A study by the University of Hawaii’i found that honey does demonstrate an ability to root plant cuttings but it wasn’t as effective as synthetic rooting hormones. 
This is just one small study and although honey doesn’t have the same fast results as synthetic hormones, it can increase the success rate when propagating plants and you’ll see more consistent results than using nothing at all.
Cleanliness is also an important factor when propagating. Cleaning and sterilizing your equipment is essential for creating healthy new plants.
Honey rooting hormone recipes
Most recipes for honey rooting hormone say to mix one tablespoon of honey into two cups of boiling water, but I prefer to use the honey straight out of the jar.
The natural antibacterial and antifungal properties in honey are destroyed when honey is heated, which is why it’s best to use raw honey. (Regular honey from the grocery store has been heat treated, so it won’t help with propagation).
You can also add a pinch of cinnamon to the raw honey.
Cinnamon has antibacterial and antimicrobial properties that help to protect the cutting and allows the natural rooting hormones that are found in the green growth of the cuttings to produce roots.
Which plants can be propagated with honey?
You can use honey for just about any type of cuttings including soft-wood, green-wood and hard-wood cuttings including rose, camellia, hydrangea and geranium. Even succulent cuttings can benefit from honey.
How to use honey for cuttings
The first step is to prepare your cuttings. Depending on the plant, the cuttings should be between 4 – 6 inches (10 – 15 cm) in length and cut on a 45-degree angle.
The best time of year to take cuttings is late spring or early summer. Cuttings taken at other times of the year can still be used, but they may take longer to form roots.
Once you have your cuttings ready, dip each cutting into the honey and then make a hole in the potting mix with your finger for each cutting.
Keep the potting media moist and you can expect roots to form in 7 – 14 days.
Succulents can be dipped in honey and placed on top of the potting soil. In a few weeks’ time, roots will start growing from the lower part of the leaves.
Honey can also be used for water propagation. Just dip the cutting in the honey and it place it straight into the water.
Once the root gets to about an inch (2 – 3 cm) in length it can be potted up.
