starting to die back is not completely brown, garlic
can be pulled early or later than peak time for a
variety. you can tell peak time by how the tunic of
the bulb looks when you lift it. if it is cracked
open and exposing the cloves to the soil then it is
too late. if it is still fairly moist and flexible
it's too early. usually i can judge when to pull
mine by when half the leaves have gone brown. i only
grow the one type so i don't have to guess about
when.
pulling early means the bulbs will be slightly
smaller and it will take more time to cure before
the garlic can be put into storage.
any green is still photosynthesizing but once
pulled there's nothing more coming from the roots
so will the plant send moisture from the cloves in
the bulb to the leaves? i don't think so if you
look at it once the roots are dry there's not too
much going on between the leaves and the cloves or
vice versa. as some evidence for that i don't see
shrinkage of the cloves as the leaves are drying
down and turning completely brown. i also don't
see expansion because i don't leave the garlic in
the sun while it cures and the only way it would
be expanding would be if the leaves were sending
energy to the cloves, but without roots and water
in the plumbing i don't think much of that would
happen.
the garlic i grow is a hardneck garlic so there
is no weaving of leaves to get a braid of garlic
to hang. i don't mind if they turn brown and fall
off, eventually when they are dried i will remove
any of the dried leaves and trim the stem of the
stalk off so it will store more easily.

after garlic is lifted the scapes will not drain
the life out of a bulb. once the stem is dry nothing
much is going in or out of the bulb or the scapes via
that route. some evaporation happens and that would
be normal but i don't think it is significant enough
to worry about.
the most important things about growing large bulbs
of garlic are starting with the largest cloves, having
decent soil, enough room between plants with no weed
competition, full sun (and thus also how long they are
left to grow) and regular watering. trimming off the
scapes does very little overall to bulb size (compare
the mass of the bulb vs. the mass of the scapes - a mm
per clove? perhaps... by lifting early you may be
making more of a dent in the size than what would be
contributed by trimming the scapes). the size of the
bulbs will also be influenced by what variety it is.
this is all written from my experience and not based
upon any super precise scientific studies other than
what i've observed through the years and working with
the same variety of garlic for most of those. the
factors i listed above all are significant and any one
of them may limit the bulb size.
