Yes, I think planting by watching nature is a good idea.
There was a researcher in Alberta who was documenting how to relate nature signs to planting times. I'll need to see if I can find her work again.
No frogs near here so:
When daffodils bloom, plant peas?
It is called Phenology---planting by signs of Nature.
We should test some of them, as we plant our gardens.
There was another for when lilacs bloom???
The benefit of planting by Nature's signs is that weather is taken into account.
The dates on the planting calenders are only approximate and may not apply in some years if weather is different from the average.
