A friend of mine recently reminded me that I could write about rooting hormones on my blog. I had completely forgotten to cover them before now. I have to admit, I haven’t used them a great deal because I’ve never had any need of them (which isn’t intended to be a flex, but I suppose it kind of is). Nonetheless, I’ve done a fair bit of research and I’ve used them a few times for conventional outdoor gardening rather than for indoor plants.
Rooting hormones can come in powder, liquid or gel form. In all three cases, you simply dip the bottom of the cutting that you wish to root into the rooting hormone. Remember that the node from which you would like the cutting to root must be dipped into the hormones. Different brands and type of rooting hormones will have their own instructions, but they should generally be used in this way. Do note that when using a liquid fertiliser, it should be poured out of the bottle before use. This means that any diseases or bacteria being carried in one cutting won’t be transmitted to others through the rooting hormone in the bottle.
Commercial rooting hormones work in two ways: They stimulate root growth by manipulating the balance of hormones within the cutting that they are being applied to as well as stopping the growth of fungal and bacterial rot/infection. As an alternative, you can use a number of natural substitutes, including honey, fresh aloe vera, apple cider vinegar and human saliva. However, these alternatives do not promote growth, they simply halt any decay and infection. However, it is said that rooting a cutting in the same water that a cutting of pothos is sitting in will encourage rooting, as pothos supposedly releases plant hormones that encourage root growth. I’m not sure how true the last part is, but many people in the houseplant community seem to believe that that’s the case.
Anyway, that’s really all I have to say about rooting hormones, since they’re really quite a straightforward tool in our gardening. However, if you have any questions, feel free to email from the contact tab.
