Our honeybees love our thistle patch, so I don't want to eradicate it. When they go to seed, can I cut down the stalks and burn them to reduce seed distribution?

You can spray only the plants you want gone with 20% vinegar
whatever you do, please don't let them go to seed - just one seed produces 5,000 plants!
Bag the flower heads before they set seed - usually they set seed very quickly so you must be vigilant - and then throw that in the trash where the seeds can't escape, or burn it - or else you will be creating thistle patches for the whole neighborhood and farther out! Thistles serve a purpose for rebuilding disturbed ground in the wild; you often find them on logged sites...
Canada thistle is a class C noxious weed so do not knowingly proliferate it. There are many other less invasive pollinator and bird flowers to grow.
