Ben - I use straw on my garlic for thermal insulation, for blocking
light (to promote root growth in the fall), and for moisture
retention. The straw also blocks weeds. I would feel that black
plastic wouldn't contribute much to those needs/functions.
I'm in northern Virginia. I'm digging garlic right now. This is the
first year that the soil under the mulch has been DUST DRY. The
garlic has not - - apparently - - suffered, but it would have been
better to have watered a few times, I'm sure.
Incidentally, unlike many, I leave my straw mulch on all summer. (I
do not rake it off as the soil warms.)
Again, I'm pretty happy with the garlic that I grow.
