Memes are filler images, you're welcome
So I'm taking a landscaping class this year because I'm thinking of potentially getting into landscape or garden design, and learning about why plants react to some things the way they do is just so interesting!
Like, I already knew that trimming the main vertical growth point of a plant activates the lower auxiliary nodes/growth points causing bushier growth, but learning about all the hormones and whatnot is just so interesting!
Apparently, the presence of the main growth point or apical bud/growth releases a hormone called auxin in the plant which actively inhibits the growth of the lower auxiliary nodes. When this is cut or damaged, the auxin levels drop and the auxiliary nodes start to activate because there's nothing stopping them.
That's also probably why notching fiddle leaf figs and dracaenas works to activate lower growth points, because it causes the plant to produce less auxin and more cytokinin, a hormone that helps with growth and cell division.
Ok that's enough of my nerd rambling, I hope at least one of you found this as interesting as I did đ

So cool! Do you have a book youâre reading for it? Iâd be interested! I have a book âLife in the Coldâ about winter ecology and itâs fascinating!
K, this is the most informative post I have scoured the internet for!!! Please, I need more. đ I’m in Human Phys right now and all I have been doing is trying to understand the bio of plants! Main vertical growth point would be where the plant is already putting out new growth, correct? I’ve always been curious about the nodes as well. One goes in water & the other sprouts? I’d love to know more!
