For weeks now curious family members and spectators have said, "Your squash is ready." and I say "No. Be patient. You have to wait until the stems turn brown".

When a squash grows in the wild there is no one
there to pick it. When does it fall from the vine?
When the vegetable matures and the stem withers. Turning brown indicates there is no nourishment passing through the plant to the squash.
The large squash to the left is a perfect example. Shown here hanging from the arbor, it has been looking large and fine for months.
But not ready til this week.
Notice how dry and brown the stem has turned?
You can't see it but it actually has a crackle to it.
Look at the additional photo below,
the withering vines seem too dry to do anything.
But it is all part of the process
and picking too soon will only yield
under-ripe, overly-wet produce.
