More about finding a variety you like. Some corns are starchy and some really sweet.

We were hit with terrible and unexpected hail last week and because of this some corn plants have tassels early due to the stress. I keep reading everywhere why it’s happened, but NOT what to do next. Anyone experienced this before? Should I leave, pull them up etc?

Depends whether they can pollinate the corn ear.

Q1. Is Corn a Vegetable or Fruit ? To confuse the issue further, Berries have their seeds on the outside, Fruit has the seed on the inside. Q2. I ask this question for the distribution of NPK in the plots. I have Roots (N), Fruit (K), and Leaf (P), the garden has been farrow now for about 3 years so should be pretty good Kind regards Wayne McClelland
