Our Comprehensive Buying Guide
Many people wonder what is in rooting hormone solutions and the answer is not that complicated. Most rooting hormones contain synthetic substances that mimic the natural growth hormones of plants. The most used active ingredients that are present in these products are indole-3-butyric acid and naphthaleneacetic acid.
Indole-3-butyric acid is part of the auxin family and you are probably going to hear about auxins a lot when someone will explain ‘what is rooting hormone made of’. Indole-3-butyric acid is a natural auxin, while naphthaleneacetic acid is a synthetic auxin. Auxins are the first growth hormones that were discovered and have been used since then with success.
Both of them together have great growth effects on plants, but, if used in high amounts, naphthaleneacetic acid can become toxic and kill the cuttings.
A good root hormone solution may also have minerals and vitamins that feed the cuttings and help them heal faster by providing everything that the roots need in order to grow healthy and have, eventually, the ability to help the plant reach maturity.
How do rooting hormones help cuttings?
Using rooting hormone solutions is a practice that most gardeners employ and it is very healthy and productive to do so especially if you want quick results. If we talk about affordable rooting hormones or cheap rooting hormone solutions, they have the same principle that they use to help a cutting make roots.
The ingredients in the product are absorbed by the cuttings which use them as growth hormones in order to build the new cells they need to grow roots. As we have said before, the minerals which are probably not present in the cheap products will help the cut heal faster and will protect the plant from disease.
The difference between letting the cuttings produce their own hormones and helping them with the additional solution is that the roots will grow faster and a lot stronger which is really important if you want to have future healthy adult plants. You will see the effects in about 3 to 5 weeks, depending on the type of plant you want to propagate from cuttings.
What are the rooting hormone types?
Rooting hormone powder is the most sought-after because it is very easy to use. The product usually comes in a plastic container that is sealed. What you have to pay attention to while using this product is not to contaminate it, so you should put some powder aside in a small container and dip the cuttings into it until it covers the whole cut of the cutting.
If there is any product left, throw it away and do not put it back in the original container.
- Liquid rooting hormone
If you have read every rooting hormones review from our list, you might have noticed that some products are ready-to-use and some of them are concentrated. This is usually available for liquid formulas as well. The thing is that it is important to get informed on how you have to dilute the product in order not to kill the cuttings, which is pretty easy.
Compared to rooting powder, a gel product is relatively cleaner to use and you will not need any extra utensils in order to apply it. It works really well as a rose rooting hormone and is useful for a lot of other types of plants. This too can come as a concentrate, but it is usually ready to use.
The great thing about it is that it sticks to the cut and penetrates it really well, so the cutting will be able to use it very effectively.
Frequently Asked Questions:
Q: Is rooting hormone necessary for cuttings?
If we talk about easy to root cuttings, the use of rooting hormones is not compulsory. However, you will be sure that every cutting will become a plant only if you use hormones. Difficult and moderate plants in terms of chances of growing roots usually need rooting hormones.
Do not think of rooting hormones as a bad thing. Studies have shown that they are perfectly safe to use if you use them according to the instructions. Ornamental plant cuttings will develop roots relatively quickly if you use hormones and you will be able to enjoy them fully.
You can try to root cuttings without using hormones and, on the sides, use hormones for some of them to see the difference. You will not want to root any cuttings without hormones again because the effects will be noticeable and you will not lose any cuttings if you decide to follow this process.
Q: How long will a rooting hormone take to work?
This usually depends on the type of product that you are using and it also depends on what you understand by ‘work’. Most rooting hormones help the clone develop roots and also help the roots go through all growth stages. If you use cheap rooting hormones they might help the root to develop but not further than that.
If we talk about how long it takes for the cutting to grow small roots, you have to be patient because it usually takes an affordable rooting hormone about 3 to 5 weeks to get good results. However, there are products that are more effective and help the roots grow in about two weeks.
A natural rooting hormone will not be able to provide results in just 2 weeks, but you will be able to enjoy very healthy plants. The key is to use it exactly like the manufacturers have instructed you to.
Q: How to use rooting hormone?
The use of a root hormone solution depends on the type of product you get. If you decide to buy a rooting hormone powder you will first have to check if it is a concentrate or not. Most of them aren’t, but it is important to know because otherwise, it’s possible to kill the cutting. You will have to stick the cutting in the powder and try to cover all the cuts.
It is recommended that you use it in a separate recipient in order not to contaminate the whole product. You will be able to use a rooting hormone gel the same way. If it is a concentrate, you will have to dilute it in order to have the perfect concentration for your plants and this type of plant rooting hormone comes with special instructions.
Granules usually have to be added to the soil either the regular way or by inserting them into the hole you want to put your cutting into.
