Afrance,
I really agree with Tom tjg911 on the growing technique.
Garlic will even grow during the winter months, mainly
because, though it’s freezing cold the ground as well as snow cover
is insulation in effect. Planting 2” below the surface,
freezing and thawing in garden soil does not normally heave the soil
to the point where the cloves are damaged.
But in a grow bag above ground the environment is much different,
and the cloves are much more susceptible to freezing and heaving.
I have never seen growbags advertised for growing garlic during
any season by any vendor. I guess if you don’t have garden space
your options are limited, but I wouldn’t waste the bag and potting soil.
I have and use tomato growbags during the summer and know they
are affected by the environment as I’m hoping to get another year out of
mine purchase in 2010. While the ones I got from Gardener’s Supply are
probably the best quality I see deterioration just be usage.
Anyway, you can experiment and do what you want but if you’re looking
for opinions, that’s my 2 cents. -Randy
