[Help] What is the lifespan of a leaf, on average?

[Waffles]

I know it may sound like a weird question, but I need an answer.
From its "birth" to its inevitable fall (pun intended), how much time could pass?
I believe it depends on the type of tree. Let's say, an oak.

1 second to forever/indefinately.theres too many factors to take into consideration.
im sure there will be studies that you could read through on the net.

I can't find any concrete answer for "caduc" trees (I'm afraid I don't know the exact term).

[eddiepc]

caduc means deciduous like a seasonal tree/plant.
if a tree/plant was outside in britain and it was healthy throught its season then the leaves would live about 6 months or a bit longer spring till autumn
but if the tree or plant was inside in human controlled conditions(kept in a summer like condition) the leaves could live forever

Alright, thanks! That's all I really needed.

im not a plant expert,i do grow a few flowers though .
plants react to the seasons so if you controll the seasons you control the plant.

Makes sense. I guess I didn't think this through. From autumn to the end of winter, no leaf survives. Thus, it lives the other 6 months.

The last leaf clings to the bough
Just one leaf, that's all there is now
And my last hope live with that lonely leaf, lonely leaf
With the last leaf that clings to the bough

Last summer beneath this tree
My love said she'd come home to me
Before the leaves of autumn touched the ground, touched the ground
My love promised she's be homeward bound

Then one by one the leaves began to fall
And now that winter's come to call

The last leaf that clings to the bough
Just one leaf, that's all there is now
Will my last hope fall with that lonely leaf, lonely leaf
With the last leaf, the last leaf
With the last leaf that clings to the bough
Bough, bough, bough ...

Plants mostly have triggered cell death. Otherwise they're effectively immortal. I have several plants which are years older than they're supposed to be because I understand what triggers cell death - in this case it's flowering.

Another example is tomatoes. In northern climates they're considered an annual but in their native habitat in South America they are perennials.

A season is the general answer.

A plant/tree has two cycles, a veg cycle and a flowering cycle. Although you can get auto flowering,generally a plant/trees veg cycle (leaf and stem growing and eventual dying off) is controlled be the amount of daylight passing over its particular location. we call these equinoxes & solstices

Outside of this however, a tree or plant will sacrifice leaves even stems.branches for the greater good of overall survival. Then infection can cause random loss. Outside of this if we were to artifically create daylight and maintain feed, theres no end to the control you can have over a specific cycle.

So im not sure we can really calculate the average all things considered.

So, it'd rather be 3 months?

[ChaffyExpert]

probably longer than you think, if you leaf it alone.
