Is it true or just a myth that tree leaves turn up/drop down before a rain storm?

Question

My grandparents used to say that it was going to rain when they saw tree leaves drooping downwards, however recently another person said it was going to rain when the leaves start to turn upwards. Which is true and what one is a myth, or are they both right/wrong?

Answer 1

Both are true. depends on the tree. some trees need more root water and will turn their leaves downward to aid the flow to the roots and some need water all over and will turn their leaves upward to cup the water.
Isn't nature amazing when we take the time to stop and watch how it reacts?

Answer 2

The leaves droop downward when the tree needs rain; the leaves turn upward before a rain.

Answer 3

In my experience, I've seen trees turn their leaves upward when they sense rain in the air (usually before the rain starts). It could be that some types of trees turn their leaves downward but none that I've ever seen.

Answer 4

Leaves turn upwards to grab the water .Proving trees are alive. Leaves that turn down mean they have not had sun in a while, and are trying to get sun, usually in a cloudy day.

Answer 5

I'm not too sure about that But my mimosa tree closes its fronds before a rain and I've always heard that in a drought pine cones will open up to catch water and close when they have had enough.

Answer 7

lots interior the way evolution in basic terms happens, wood have been right here continuously and the experience the oncoming rain. the leaves turn over, and that i've got no concept what the reason being, on instinct.

Answer 8

Note that the leaves turn based on the increasing humidity in the air - it's not magic.
