Can you split broom even if it almost looks like a tree now? It's about 5 to 6 feet high and way overgrown. It was here when we moved in about 4 years ago and has completely taken over the spot and either needs to be split or cut way back, hoping for the splitting though. Please let me know and, if so, is that done now in spring? It has just bloomed.
If it has multiple stems/trunks coming out of the ground, it can be split. This article will help: https://www.gardeningknowhow.com/garden-how-to/propagation/propgen/dividing-plants.htm
I planted four Spanish brooms in March and they are just now starting to do well. However, I noticed a bunch of new sprouts looking dead and upon a closer look saw numerous very small little yellow/black caterpillars that had invaded. I have been unable to find out what these are, but I was told that an insecticidal soap would take care of the problem. Would you agree with this advice. Thank you.
Yes, insecticidal soap should work fine. You may also want to consider using neem oil or Bt (Bacillus thuringiensis). Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm

Hi I have a beautiful yellow broom in my yard but might be moving over the winter. I am wondering if there is a way to remove part of it to take with me? Thank you so much
You can try cuttings but that will prove very difficult. If you have accest to digging up a small part with, both, a top and roots, then you can start one from this.
I have an establised broom bush which was blown over recently in the high winds causing the branches to split. I have now cut the damaged branches to within 4 or 5 inches from the ground and my question is will it start shooting again from either the end of the cut off branches or from the base please?
This will be fine. They are very hardy, and will likely shoot new growth from all ends! Here is an article that will help: https://www.gardeningknowhow.com/ornamental/shrubs/broom-plants/information-on-broom-shrubs.htm
My broom bushes do not get yellow flower and I don’t know why. Been planted for about 5 years. Had flowers when I planted them but never bloomed again.
It could be the quality of your soil, or not enough sun. If they are getting full sun, then I would recommend fertilizing at least once per year in spring.
