nothing wrong with using them any time you
want as they are an onion right? so use them
now or after they've died back completely or
and place in between.
in general with bulbed crops like onions
you'll get the biggest bulb when the leaves
have died back almost completely, but many
people will lift their onions before that
stage because of chances of them rotting in
more moist climates. and they need to dry
to get ready for storage. if you wait too
long into the cooler and wetter weather you
may not get them dried well enough, etc.
dig some up and look at them. when you
get enough of them growing you can pull some
every once in a while just to get a sense of
how they grow and when they divide and if
they go dormant and for how long, how the
new bulbs form...
if they're still actively growing i wouldn't.
i don't stop watering the onions here until they've
the thing with onions like these is that they
multiply so you can start using them anytime
they reach a size you want and you'll likely
have plenty of smaller replacements to replant.
dry them well and then store in a dark place
until replanting time or just take your chances
and leave some behind for every plant you harvest
and they'll likely regrow.
move some dirt aside and see how they're doing.
that's how you learn. check things out, look,
and of course put some in more than one location
because you never know what the weather and soil
will do. nice to have a few someplace as a backup
in case the other spots fail, etc. eventually you
may even find they've become too many.
for me this year, we're mowing the spot i wanted
to dig up all the garlic to get it out of there.
injuries have prevented me from getting that done
so Mom will mow it until i can get back to it.
