I noticed small white thorn-like textures on my kale leaves in my garden. They are sharp to the touch. Do you know these are? Is this normal/OK to eat? Is it necessary to treat?
I have heard reports of some varieties having these hairy little thorns. They will not harm you and will cook down in the wilting process.
Each year I develop small worms on my flowering kale. I have been told to use tristar incesticide.....your suggestions? Thank you.
Neem Oil is a good treatment. Use it throughout the growing season.
In severe cases Bt or Bacillus thuringiensis is a good choice.

Best way to stop insects from eating Kale leaves. We have a great crop but some leaves are far more eaten than what is left. I've caught numerous leaf hoppers and a couple of grubs, but more is eaten daily. Two plants had scores of baby eggs, mainly in hollows underneath. I wonder if liquid fertilizer may help.

I was wondering what does it mean when flowers start growing in the kale? Are you supposed to pull them out or leave alone? Also, after I pick the kale, will it grow back?
Your plants have bolted or gone to seed.
This is generally caused by warm temperatures.
Harvesting is best done before your plant goes to seed.

Why does my kale (both on the stems and leaves) have tiny prickly thingys? Is it bad kale?
It's hard to tell from your photo exactly how large your kale leaves are, but from what is showing, it looks like this is perfectly good kale and probably ready to harvest (don't let the leaves get too large or they will turn bitter).
The "prickly" things aren't anything to worry about (the leaves on my kale are slightly pointy as well), and should come right off with a light rinse, or you can simply rub them off before eating your kale.
These articles provide some good information about growing and picking kale:

I have been growing my first herb/veggie garden in raised beds this year and went to harvest some of my kale and it looks like this, just on the one purple plant underneath. Is it rotten?
This looks like a heavy aphid infestation (Mealy Cabbage Aphid most likely), including both the live bugs and their shed exoskeletons. Remove any leaves where you see them and discard far away from the garden. Here are some articles on getting rid of aphids:

My flowering kale grows about four feet tall. Is that normal?
Your plant is probably bolting, or producing flowers and seeds. This is normal, but many gardeners will try to prevent it. Here is more information:
