Monstera deliciosa

Hi everyone I have a monstera deliciosa (Swiss cheese)
I’ve had this for around 24 years now, I took this cutting from the mother plant that must have been around a similar age.
I’m finding that the leaves are always small, could this be down to condition’s or that the plant is just old.
Any help would be greatly appreciated.

 

Its a bit odd, only the lower leaves actually look like a cheese plant.
I think it must be lack of direct light.

Cant think of another reason other than has it been repotted at any time in the 24 yrs.

 

Yes it has, it was repotted several times and just a couple of months ago thanks

 

Monstera deliciosa need bright light but do not tolerate direct sunlight. I had one in my office at work which I inherited when my predecessor retired. It thrived on neglect and banana skins. The leaves were huge but it was in a fairly dimly lit corner away from the window.
My office was being pulled down when I retired (like Fred West's house) and it was too big to take home, so I offered it on the e-noticeboard and another department took it in.

 

I give it food once a week, it has lots of new growth, I thought the age of it could be the cause, I’ve read they only live for around 40 years, thanks

 

On sunny days I pull the blind on so it doesn’t get direct sunlight just bright light.

 

Yes but the juvenile leaves are higher up the plant than the adult ones.
Something really odd going on.

They will take direct sunlight if they are used to it.
I got rid of my big one last year and it had diffused sun light in summer and direct sunlight in winter.

 

Hmmm. The growth looks "watery" in a way that the plant is just pushing out new growth rapidly without bothering to grow fully formed mature leaves. Usually that would indicate too much fertiliser, water and warmth, but the position looks bright enough to support it.

I would take a cutting and grow it in a different position to see how it grows.

Does it make aerial roots? I can't see many in the photos which is also uncharacteristic. High air humidity and less water on the roots usually suits Monstera well.

The plant looks healthy and nice, it's just not very Monster-ish.
