Non-violence is the greatest Dharma; So too is all righteous violence.
Do what inspires you !!
When we started learning languages with script, we started forgetting the raw, real,emotional non-script language of plants. We stopped communicating with the plants and trees.
Pouring dirty water on the plant is not a bad thing. The plant needs water, as long as it does not have chemical content in it, I think it would be fine. We will not like having dirty water on ourselves but that can't be compared with a plant. The plant grows in the mud and we are not. We live in houses which has high-quality tiles or granites.

Even this challenging situation would ease
But if at all it is proved beyond doubt someday that plants do have feelings and emotions, we would be having plant activists who would protest against cutting of plants or using their flowers or eating vegetables and imagine such a situation. May be that is one reason why there is no serious effort to establish whether plants actually have feelings.
Anyway, what difference does it make in a world where we are least bothered about the pain and emotion of even fellow human beings?

My grandmother had told me that the real hermits living in the forests live by eating the fruits falling from the trees and plants and not plucking from them.
Such things may not be practical now. I have read about some farms using mild music which enable the farm plants to flower fast and grow well than in the ordinary circumstances. As there is life, logically there would be reactions and responses from plants too.
