I live surrounded by Ohio and we regard as we planted the seed surrounded by our garden too insightful. Will things still come up? We planted corn, watermelon, peas, peppers, carrot... This is our first garden...

We planted corn, watermelon, peas, peppers, carrot...
This is our first garden and we planted everything about 6 or 7 inches vast. It has be planted for about 3-4 weeks and with the sole purpose a few little sprouts.
Answers:    I'm in Ohio, too. The soil have stayed cold much later than most years.

Corn, beans, watermelon, pepper...all involve WARM soil to germinate. They'll just sit here until it warms up. Being so open - it will take a short time longer to warm up - AND to work their course to the surface.

Carrots take forever to germinate within any circumstances.

It will definitely supply time when you've planted them so deep. Corn, Watermelon, peas...I'd plant around an inch down. Peppers, 1/2 an inch. Carrots...just a fine covering of soil. They obligation light to germinate.
No - as a rule of thumb, you plant seed only 2-3 times their size within terms of depth - tremendously few vegetables get planted deeper than 1/2". Whatever have come up has worked its little buns rotten, so you will see a few of those but everything else is just rotting down here, you should just get hold of more seeds and overplant the nouns.
