They are just here and there in along with the hedge.
Not sure about the root rake as it may bring fenching with it too
yes a cool burn cracks the wax on seedThe seed bank in the ground wants you to burn it as it stimulates regrowth unless the temperature is above something like 120 degrees C. This scorches the seed and kills it. Best way is a land rake on a digger, heaped and burnt in massive heaps so you get a hotter burn. Then plant something that smothers the regrowth as shade is its nemesis.

know years ago guy did 3 burns. standing green sprayed and burnt and sprayed rolled burnt
the green burn too cold cracked alot of seed
spray burn a bit better but most of fire up higher
spray and rolled burn fire on top of ground cooked top few inches. wrecking the seed bank dose also kill off a bit of soil life at same time
