If the silk on the ears is brown and dry its time to harvest. I am assuming that you have planted sweet corn.

When the silk starts to turn brown, gently turn back a bit of the husks, and press your thumbnail into one of the kernels:
If it pops, and the juice is clear, it's too early--gently replace the husk, and wait a few days.
If the skin is too tough, and the flesh too doughy, to pop, it's too late--make creamed corn. :)
If it pops, and the juice is milky and sweet, it's harvest time!

Thank you both for your help!

I have s ridiculous amount of zucchini!

And a great family recipe for ....."gagutts". Hit me up if you want it!

lol! I had to look it up, but gagutz is another name for cucuzza "squash"--actually a white-flowered gourd. From what I know, any recipe for cucuzza should work fine for zucchini, too! :)
