I'm afraid that my cabbage, tomato and pepper plants may freeze outside. So I want to know if they will still grow and harvest if transplanted indoors.
Transplanting larger plants during the growing season is difficult, especially with vegetables. While you can attempt this, there is no guarantee that those you move will make it. I would opt for outdoor protection before attempting to move them. Placing a sheet over the plants at night and removing them in the morning should help.

If you are expecting freezing temps, however, there is little you can do for your tender vegetable plants.
I planted cabbage seeds last spring in good, black soil (composted for 10 years). Now in autumn, I have sturdy cabbage plants but no heads. How come?

Cabbage plants store food in their. . . ?
My cabbage did not head, brussels did not mature, kohrabi did not form, tomatoes stopped growing, no eggplants on bushes, no peppers, no beans, no corn - in other words my entire garden failed. I have been an organic gardener for over 50 years. Please tell me what happened. Was it all weather related?
It could have been weather, but typically when you have an across the board crop failure like that, some element is missing from the soil. I would strongly recommend taking a soil sample to the local extension service and having them test it. A severe micro nutrient deficiency (of which it could be many and only a soil test will tell) could cause this to happen.
I am in Okeechobee, Florida. I planted my cabbage in September when it was hot. It usually cools off in October, but it didn't. The cabbage plants have very big green leaves on them but they will not form heads. I cut the bottom leaves off of one of the plants but it didn't help. Can you help me?
They need cool weather in order to form heads. You can help keep them "cool" by placing mulch around the base to regulate the soil temperature. This article will also help: https://www.gardeningknowhow.com/edible/vegetables/cabbage/cabbage-head-formation.htm
I'm trying to grow winter vegetables, but something is eating holes in my cabbage leaves. Good strong, healthy plants except fot all the holes. Tried putting snail food around but no change.
It could be slugs or cabbage worms. Here is an article or two that you may find helpful: https://www.gardeningknowhow.com/edible/vegetables/cabbage/protecting-cabbages-from-slugs-how-to-keep-slugs-off-cabbage.htm

My cabbages leaves were full of holes - like lace. I was convinced it was caterpillars or slugs. However, I've recently caught the culprits in broad daylight...Pigeons pecking at the leaves.
Can you eat cabbage that has not formed a head?
While less than palatable, it's still technically edible. If you're having difficulty with head formation, this article may help: https://www.gardeningknowhow.com/edible/vegetables/cabbage/cabbage-head-formation.htm
