Mrs. Bradley,
It is definitely a good start! You will see the ears starting to grow and silk soon, that's when you know you might have corn. (Those tendrils are called tassels.
)
I grew up in deep south Texas and my dad always planted at least 20 acres of corn--just for my family!!--Of course we always had an abundance, and what we couldn't pick, we would let dry, then come through in the heat of summer on a tractor & trailer and pick the corn for the animals.
The tassels are usually the end step of the vegetative stages of development, and soon to follow will be the reproductive development (the kernels will grow, fill with the milk, and then turn into the delicious yellow kernels that we so love to devour)-yummmmm. You should start seeing silk on the husks in about a week.
How much corn do you have planted? Sometimes corn doesn't do too well in a "stressed" environment, or with too little "friends" around--lots of corn stalks.
I think you should get the best results if you can protect a smaller crop from wind or other things that might stress it out. If it's not stressed the silks will catch the pollen needed from the tassel to start reproducing (making the kernels), and the kernels will develop without a hitch, otherwise it might be a little delayed, and the kernels will not produce.
About 2 weeks after you see the silks appear, then the kernels/blisters will begin developing (they're called blisters at this stage because they're so small).
You'll want to pick the ears about 3-4 weeks after the silk appears, any longer and the kernels will start hardening, and won't be nice and juicy.
I hope you get lots of corn out of this! I just love fresh corn on the cob!
