This is a Free Step-by-step tutorial on how to make a natural rooting hormone for your chilli seedlings. This rooting hormone can be used for seedlings and also to aid cuttings when propagating plant material. In this tutorial we will be making our brew from Willow tree cuttings.
Willows are fast growing, deciduous trees that can be found along rivers and in most city parks. The Willow belongs to the genus "Salix" - of which there are about 400 different varieties. But for this exercise we just need any one of those 400 that you can get your hands on. But please note, this is a seasonal exercise that is applicable at spring time when the Willows are bursting into green with new growth.
The Willow is truly an amazing tree that has been used for thousands of years for simple tasks such as making baskets, rope and paper, to more complex medical applications such as pain relief. Chewing on Willow bark was prescribed for fever and inflammation and the bark from certain varieties of Willow has even been used as a pain killer, as it contains Salicin which is similar to Asprin (Acetylsalicylic Acid). So, not just a pretty tree, but a hugely useful one as well.
But, without a doubt, the most impressive attribute of Willow trees is their ability for growth. Not only can Willows grow at an amazing rate, they are also able to shoot roots from broken off branches and can even do this when planted upside down! And the reason for this is due to the naturally occurring hormones in Willows - Indolebutyric Acid (IBA) and Salicylic Acid (SA).
Now the function of Salicylic Acid is as a hormone that triggers a plants resistance response when being attacked by pathogens. That is a good thing, this will improve a plants resistance to pathogens. Indolebutyric Acid is a hormone that stimulates plant growth. Which is just what we want for our little seedlings. And what better than to get both these hormones from one source.
Come spring time, when the Willows are bursting with new lush green growth, both IBA and SA are present in high concentrations in the new green growth of Willows. Please note new green growth of Willows, not the older established growth.
What we are going to be doing in this exercise is make a brew that contains IBA and SA. For this to happen, we need to leach the IBA and SA from the Willow cuttings into water - and it couldn't be easier. At the end of this process you will have a slightly greenish brown tinged water that has IBA and SA in it, that will be an effective, natural rooting hormone. We like to call it Willow Brew. And this is how it is done…
