Rooting hormone should be stored in a cool, dark place. Check the expiration date before using, as the chemicals can break down over time. By Monica Weymouth January 28, Save Pin More.

If the leaf has a short stem, as is the case with African violets , dip the stem in rooting hormone and plant it in the potting soil just like you do with stem cuttings, by sinking the stem up to the leaf into the potting mix.
In some cases, it is necessary to cover the backside of the leaves with the rooting hormone and lay them on top of the moist soilless mix and lightly press down until the leaf touches the potting medium. Keep all rooting plants out of the direct sun until they have developed a robust root system.
Root cuttings are just that: pieces of the root of a parent plant that will eventually produce a new plant. Fall is the best time of year to take root cuttings so that the root cutting has the entire winter to produce a new plant in time for spring. Rooting Hormones. Michigan State University Extension.

Powdered forms of rooting hormone are a bit less effective than liquid forms, but they are easier to work with and are are less toxic.
Powdered forms are a good choice for beginners. Liquid forms of rooting hormone are available as a ready mixed solution or as a concentrate.
If it is a concentrate you will have to dilute it, according to directions, before you use it. Once diluted it is only good for a day — discard unused liquid. The liquids transfer hormone to the cutting more easily than powders.
It is therefore important to control the amount of time the cutting stays in the liquid. Follow instructions, but it is usually no longer than a few seconds. Longer immersion may result in too much hormone getting into the cutting, which may prevent rooting. This timing issue is one reason that powders are easier to use. Once treated, stick the cutting in the rooting medium following the procedure described above for powders.
There are also gel formulations like Clonex, on the market. Some people really like the gel, but powdered rooting hormones are more popular. As discussed in Rooting Hormones — What Are They , rooting hormones are available in different strengths concentrations to more closely match the kind of plant you are propagating. Some products come in only one strength, and some come in multiple strengths.
The liquids can be diluted to the strength required, which is one of the main reasons for using liquids formulations.
If you think about how the hormone is applied to the cutting, you might realize that the amount added is quite variable. Some people will dip more or longer, and then shake off less. For the home gardener it does not have to be that precise. I tend to use the higher concentrations recommended for woody plants for two reasons. I grow more woody cuttings, so I have the right one most of the time. Secondly, if I want less for herbaceous plants, I either apply less, shake harder, or stick them in soil without making a hole first.
All of these steps cut down on the amount of hormone my cuttings get. For the average gardener, a bottle of rooting hormone is enough to last a lifetime. That sounds like a good deal. Unfortunately, the hormone has a expiration date. Some manufacturers suggest it should be discarded after 1 year. Some say it is good for two years. Chemical companies report that IBA is very stable suggesting it will last many years. No one seems to provide any real proof of how quickly it degrades.
A lot of drugs are good well past their expiration date. Solid chemicals ie powders are generally more stable than diluted chemicals, so powders probably last longer.
I suspect the powder forms have a shelf life of at least 5 years and probably more than All chemicals degrade over time. The best way to store rooting hormone is in the dark and cold. The containers are usually light proof so they are always dark. A fridge would be a perfect place for storage. Its very informative. Robert you a very patient and generous man l thank God l found this site Anyway is it necessary to cover cutting with a plastic after applying root hormone Does it have any benefits for successful rooting Tryna propagate macadamia Regards John.
I did it the same way as you, dipped the end of the sour cherry twig in the powder and then into the potting soil. Didnt shake the excess off. The soil is a bit moist as they are when you buy them. But when can I start to water the soil?
I have it in an old metal bucket that has rusted out holes in the bottom. I hope its a heat wave only, too early for the hot summer at the end of June in zone 7.
I would like to save some smaller poplars, about ft tall, that were recently toppled when the township cut the grass along the side of the roads. These trees were torn at the base no roots , is it possible to use some sort of root hormone on them? What would you recommend if at all possible to reroot these trees? Thank you. Just bought Doff Natural Rooting Powder. I want to use it also in slow growing plants.
My partner is putting rooting hormone on already rooted cuttings that have been propagating in water, rooted then diped in powder just before putting.
The plant is now making its own rooting hormone in the quantities it needs. How about animal manure as a rooting hormone? I have read that part of its odour is due to indole. Maybe the indole needs to be indole butyric acid or indole acetic acid to be hormonally active? Hi Robert: Serendipity! Happened with me today. As I was browsing to learn water culture of fresh flower cuttings, I landed up in ur home site. K Goswami India. Do any of them work at all? Rooting hormone is used on woody plants.
Hi: What if i want to root my cutting in water after applying root hormone? Does that beat the point of applying it in the first place?
Thank you, Klara. You have the potential of transferring disease from plant to hormone to next plant. To be honest, I just dip the cuttings right into the container. Good information here. I used liquid rooting solution twice on a fresh Moringa cutting. When the cutting grows will it be toxic??
Will the leaves and Moringa pod be toxic and unfit for human consumptions? Hi Robert I know I am very very late to join your discussion. I had an over whelming desire to make a comment. Well I did want to add my little bit of knowledge to this few years old conversation.
To my knowledge the fertilome liquid root stimulator is for new plants that our smaller in nature so they would have some roots already but not much. Also it says that it is very useful to use when transplanting your plants from stores or cuttings that have developed new roots it states that it works to not put the plant in shock while transplanting. It also helps smaller plants to grow stronger roots. From my experience it does seem to work very well.
I also used the fertilome liquid root stimulator on my grass plugs. I am not sure if it is coincidence or not. Thank you for sharing all of you knowledge. I thought it would be harmless till i read the label and now Im wondering if I should discard my cuttings?
It contains Haromdin 1 and Indolebutyric Acid. Does rooting hormone cause any harm to leaves if it accidentally slips on them? What would happen if I apply rooting hormone on a cutting and stays over on it before planting? Say 12 hrs? I cut my aglaonema and stick it in water for a month and it no sign of rooting. Can I stick it in root hormone and put it back in water again?
