Good idea.

In general the problem for corn is cold soil the seed does not germinate but rots. But once the seed germinates it can take cold soil. so the solution is germinate then plant. I usually plant as soon as the root sticks out of the seed. but go get them into the ground they are getting kind of big and might get root bound on you.

If you get a late freeze after putting them into the ground then cover the plants as protection against freeze. If the plant freezes and the top dies it should stay alive and send up a new stalk. corn is a grass the grow point is below ground.

What you are suggesting is pretty S.O.P. in these parts for market growers who are trying to get a really early crop that can command a higher price. I've seen them use both the spun-bond fiber floating row cover and poly covers. Just depends on the grower's choice, I guess.

Use standard-weight row cover if you can, held aloft with stakes. Hail and wind can really set back unprotected plants. I start a planting of early corn indoors no more than 10 days before I set it out (early May here), mostly to get a good stand. Then I direct-seed the main crop when the soil is warm.

What would be standard weight?

Like reemay. Looking at available products, I'd veer toward a lighter weight row cover like the one below because of its all-around versatility. Take care of it, and it will last for 5 years plus.

I started some yesterday.I was very successful using Reemay last year.I bought a roll of #9 wire and cut it into 4 foot or so lengths and criss-croosed them over the top of the 2 rows of transplanted corn.Then put the Reemay over and buried the edges so it would stay there.

I let them grow under it until they were pushing the reemay.Gave me corm 2-3 weeks earlier than the same seed planted in the ground.

Worked perfectly.

The ten day weather is projected to be in the 70's and 80's during the day and no lower than 59 at night. Do I even need to cover the plants?
