Sweetness

[Magpie]

Hi, I'm probably not the best person to comment on the meter aspect of your poem but I'll leave a few thoughts regarding the content of your poem.

Thoughts can be seeds planted in the mind,
And thoughts of you grew in a twisting vine. --- Be careful of too much repetition with 'thoughts' here twice in the first two lines, especially so considering that you use it again in the next stanza 
In every crevice a saccharine bloom, --- I personally think that this line is excellent and is the essence of your poem
As I goaded you to consume

All of my sweetness --- at first when I realised that 'all of my sweetness' was a refrain I feared for its chances of making it through to the end without being sick of it, but it's actually not that bad.

Your sun colored how my skin glowed,
With thoughts of you, milk and honey flowed. --- Where there is milk there is usually honey to follow especially when they are flowing, careful of these cliches. I've been using Google search as a cliche checker of sorts, its not foolproof but if Google text prediction gets it fairly quick then chances are it is a cliche. I had "milk " typed in and Google suggested "milk and honey" whereas "saccharine bloom" didn't show up at all.
But unattended, my insides turned to rot,
And old roots buried deep, began to knot.

All of my sweetness

Then one day you came to rip me apart,
To see if I really, really had a heart. --- the repetition of 'really' really seems awkward and unnecessary here 
Now, even as my blood drips down to the Earth,
You will never know what loving me was truly worth.

All of my sweetness
Never grew to be the fruits of your Paradise. --- "fruits of paradise" another possible cliche alert to look out for, also I agree with Todd that the poem really needs to end with your refrain for it to have its full impact.

-N.S.

You've got some good thoughts and possibilities going on in here especially with that 'saccharine' line which you should use as inspiration for the rest of the poem. The other thing I would mention is to consider your title carefully, it may seem somewhat logical to call this poem "Sweetness" when considering the refrain. But if you look at it in a way that says the refrain has the "sweetness" aspect covered then you have a free space for a new title that can be an imaginative way of drawing readers toward your poem.

I hope to see you develop this more,
thanks for the read,

Mark
