haiku

[Magpie]

on the lawn
watered by my tears
new weeds grow

Hi, I'm struggling with the second line a little bit because it is quite abstract for a haiku, and also the 'my' makes it too personal for a haiku. There are possible ways of writing it slightly differently and yet it could still retain your original meaning.
I understand why you want to use 'new' weeds grow but as a snapshot it doesn't work quite as well because to say 'new' implies knowing that there are weeds now in places that weren't there before, so in an indirect way you have involved the past whereas haiku should more be in the moment... If that makes any sense.
Perhaps you could have something like 

weeds grow
on the lawn -
rainfall

or something along those lines, actually now that I'm looking at that, I would even say that 'grow' is redundant because it is implied. Although haiku aren't meant to be metaphorical the 'rainfall' could be interpreted as the tears that you use in yours, so in theory the same meaning is kept but at the same time it is a realistic snapshot of a moment.
