The first broccoli I let grow too long. Will I get another? And if my broccoli gets flowers on it, is it still good to eat?
You will not get another head, but you might get some Mini head-like side shoots that are edible.
You can eat it after it flowers, but the flavor is normally bitter and not so tasty.
My broccoli and cauliflower plants did not form heads.
This normally happens because the soil is too warm. They just go straight to bolting. This article will help prevent the bolting so that a head will form:

My Brussels sprouts, broccoli, and winter cauliflower have been planted out about 3 weeks. I watered them in well and they are growing quite good; however, I have not watered them since, but because of the very dry weather, do you think I should water them now or leave them for the roots to go down and find their own moisture?
Most vegetable plants need at least an inch (about 62 gallons per 100 square feet) or so of water every week to survive.
This is my first time gardening and have just realized my broccoli has 'bolted'. I didn't do my homework and made a mistake of planting it too soon. Is there any way to stop or reverse the bolt process? Now that it has 'bolted', can I still get a yield from the plant?
Unfortunately, you cannot stop the bolting process now and the crop won't be any good, much too bitter. For future reference, however, these articles should help: https://www.gardeningknowhow.com/edible/vegetables/broccoli/bolting-broccoli-growing-broccoli-in-hot-weather.htm

I have black and white caterpillars on my broccoli plants. What is the best way of getting rid of them?
The following article should help: https://www.gardeningknowhow.com/plant-problems/pests/insects/prevent-caterpillars.htm
Prevention is key with regular checks of the undersides of leaves, especially during spring and summer. Simply pick off any eggs and dispose of them, along with any caterpillars, which you can either relocate or squash. They can also be dropped into a small bucket of water and drowned. Beneficial predator insects are another option for control. Some quick and easy homemade repellents to keep caterpillars from eating your plants include solutions of water with one of the following plants added: onion, garlic, chives, hot pepper (jalapeno, cayenne), or an herb (basil, coriander, wormwood, peppermint). Steep the leaves in hot water or mix in a blender and strain before spraying. These sprays will successfully repel a wide range of insects. Bt and neem oil are also effective solutions for taking care of caterpillars.
I have a patio with a bunch of containers--broccoli, cabbage, tomatoes, and some basil. There is some obvious bug damage, and there has also been some slug damage. I was going to spray neem to start with, and maybe setup some little slug traps. I wanted to know when the best time to spray neem is. . . dusk, dawn, or does it matter? I do mix the neem with a surfactant. Any info would be much appreciated.

My broccoli and cauliflower plants are well spaced out and have absolutely massive leaves, but they don't seem to be forming heads. There were plants still in the nursery that had heads! My red cabbage plants are also just leaves, and they aren't forming into balls. Is there something I can do to help them along? Thank you!
Broccoli, cauliflower, & cabbage are cold weather plants. They do best in colder temperatures,& have low tolerance of heat. The outer cabbage leaves can be tied together at the top. It helps the plants form the heads.
