I've just reluctantly had to heavily prune a 'black mulberry' tre that's thrived in my mum's garden for years - at 31' it had grown wa to big & had also begun to lean dangerously due to uneven growth Apparently it isn't a good idea to prune these trees at all, as the bleed so much when cut & are unlikely to survive 'an extreme hai cut'.
On advice taken from an ancient 'Pruning tips' book, I did the cuts a a steep angle so as rain water runs off the sloped ends, & also burn the wounds with a blowtorch to create a seal that would stop the sa escaping. Despite that, I've removed such a lot of it's branches tha it's quite likely I've killed it. Oops, sorry mum!
So, I'm wondering if it's possible to root the offcuts just in case th original tree dies?

I have a stack of them ranging from 3' - 5' long, & have burnt the end of these also to seal the sap in. What's the best way to attemp rooting?
