i have a torch that has a long time ago split into 3 and now 2 of the heads are splitting apart when they finally split completely can i some how cut it into separate torches

you could but i would wait until there are more heads.i split mine when i got 25 or 30 heads. i did this with good results every 6 months. and it is as simple as it sounds use garden snips and cut at the main stalk.
good luck
