When leaves show their undersides, be very sure that rain betides.
When leaves show their undersides, be very sure that rain betides.
Meaning in plain English
The saying treats visible leaf undersides as a sure sign that rain is coming. It gives a change in the leaves’ presentation predictive force.
Example
A reader identifies the leaf-underside cue while leaving both its cause and the rain prediction unconfirmed.
Deeper explanation and when to use it
Very sure strengthens the claim without supplying evidence or a timeframe. A useful explanation separates the observed leaf position from the supplied humidity mechanism, which is not independently verified here. A particular tree’s appearance does not confirm the rhyme.
When to use it
Use it to examine the certainty in a plant-based weather sign.
Keep in mind
No leaf mechanism, universal plant response or dependable rain forecast is established.
