It means to stop messaging first (watering) and see how many people reach out to YOU. The ones who act like you don’t exist or don’t put in any of the effort you do, are dead plants (broken relationships).
Beside this, should you water dead plants?
What can you do to revive your dying plant? Most people immediately assume that they should water it, but an extra dose of water can actually harm a plant that doesn’t need it. Instead, know that a plant’s health fluctuates if it’s getting too much or too little of something.
Subsequently, what does stop watering dead plants mean?
The dead plant is a metaphor
You make space, do the needful, enjoy the honeymoon phase, and then get too comfortable and stop valuing the things you once fought for. The act of watering the dead plant is the denial phase where you cannot accept the absence of something without acknowledging your own faults.
