My broom is beautiful but has taken over! I need to get it under control before my climbing rose vanishes behind it!
A broom shrub should be pruned when dormant (late winter, early spring) but it will not hurt it to prune some now, if you need to.
The best way to prune it is to remove some of the oldest branches/stems/trunks all the way back to the ground and then shape the remaining into the size you need it to be.
Several of my Scotch Brooms have large sections of dark brown stalks amongst the green budding stalks. Should I prune the non-budding stalks or leave them? One of them has absolutely no budding stalks - is this one dead?

Where can I purchase this weevil larvae? It's a larvae that eats scotch broom seeds.
Below I have provided a link to a directory of vendors of beneficial organisms in North America. I did not see seed weevil on the list, but there are places listed here you can contact to make an inquiry. The use of seed weevil against scotch broom is still in the experimental phase, so I would advise pursuing other measures to combat scotch broom, as discussed in the following article:

My 8ft, 10 year old scotch broom turned brown this winter. Trunk still has green but it looks dead. Is it dead?
Only time will tell if you still have a live plant.
Avoid pruning the dead material until danger of frost has past.
Then prune out the dead plant material.

The property we purchased has a very large unmaintained scotch broom. I would like to keep it if possible. Can it be cut back without killing it? If so could we cut it back some in fall/winter and then again after blooming next spring?
Hello,
Thank you for sending us your gardening question. You can trim broken or diseased branches at any time of the year. However, pruning for size or shape should only be done in late spring, immediately after flowering. If you cut it back in autumn or winter, you will reduce the next season's flowering.

My bush has grown too tall. Mine has beautiful orange flowers. The picture shows yellow flowers and seed pods, which mine doesn't have! But it needs shortened. How and when? And have they mislabeled?
They are just variations of each other, and what applies to one will apply to the other. Here is an article for more information: https://www.gardeningknowhow.com/ornamental/shrubs/broom-plants/scotch-broom-pruning.htm
Can scotch brooms be planted in a large pot, or must they be planted in ground
Scotch Broom will grow too large for containers. It would be best to plant in the ground.
