Not about Orchids but is there a way to stop rot on a leaf?

[Cymbaline]

With so many smart plant people on this forum I thought I would try here. I have this monstera cutting I'm working on rooting. It started developing a black edge.


Anyways I cut of the edge with clean trimmers ( cleaned off with alcohol ) and dusted it with cinnamon . It just continued.

I'm thinking there probably isn't way to stop the edge from dying but I thought I would ask if there is anything I can do at this point or just wait?

Also do you think it is best to let the leaf stay or cut it off?

I've heard two thoughts. A) the leaf provides energy for the plant or B) the plant is using energy to support the leaf instead of focusing on the roots?

I don't grow this particular plant... but in general, the function of a leaf is to use photosynthesis to provide the energy that a plant needs to live (food) Roots take up water, leaves utilize that water plus CO2 from the air, to produce sugars - the chlorophyll in the green leaf is an energy factory. So it's the combination of leaves and roots that permits a plant to live. I'd leave the leaf alone. It looks like it is aging... the plant will drop it when it is no longer useful. When you're trying to get the plant established is not a time to be particularly concerned with aesthetics - it needs every bit that it has.

I see no reason to be worried. The leaf will continue degrading, and will ultimately drop at the base where it attaches to the stem.

In my low humidity conditions, cuttings drop their leaves because they can't reach a water intake/transpiration equilibrium.
Making a DIY greenhouse with plastic wrap can help with that.

They're totally able to root and grow from nodes without leaves, as long as you give them a good amount of light.

Thank you! That's my first thought as well but good to know.

Thanks! I placed it my Milsbo which has high humidity.
