left behind (thank you tec, fogglethorpe & Brownlie)

[Brownlie]

I'll give you my two cents here for what it's worth

Sweating in the blaze of summer; -Language could be more concise here. I'm not sure if you need blaze or not.
pulsing through ascending vines,
raised ripe and firm.
Swollen in the sweltering heat,
bruised love-bitten, dripping -- I like the image of a bruised and swollen bite.
bitter-sweet.
Mourn the untended left behind,
lost forever to the harvest.

Not bad, I don't know what kind of rhythm you were going for here so I don't think I can make any helpful metrical remarks. My big question was whether you intended to have a somewhat ambiguous meaning for the poem or not. I think of farm workers who come as immigrants and work in dusty areas with a lot air pollution.
