im gonna give it a grow ...lol ..
The real key with one of these repairs is gently putting the plant back together again. if the break is not complete, it can be eased back into position, secured, and the sap act's like blood clotting, and the wound is restored. Even the capillary and venous congestion heals much quicker on plant tissues in generally healthy state. The only key is making that flesh to flesh contact again, in a meaningful way, that's not too much askew, or crooked, and doing it all, before an air bubble can occur (immediately) The problem with a complete bust, or a virtually compete bust, is that it detaches to easily, and you've got to hold the plant with one hand, (both ends) and tape it with another. Two experience people could be better than one, in some situations.
The other thing I do is remove the plant from direct light and give it some shade, and I gently mist the broke area several times daily, until capillary action is restored.
I've made lots of breaks, it's what I do to plants. 10-30 breaks on a single plant, sometimes, I enjoy doing it, especially in pre, early, and mid flowering periods. So I've had some fails, and many successes with healing breaks. Sorta reminds me of the extremity reattachments I've healed over the years. Convincing some 7 year old girl that the leaches were her friends. lol. Keeping the affected extremity above the heart, and raising the heat in the room to 85f for the first few days. I even took care of a guy once, who put his arm in a wood chipper, and it was sewed back on again. He was even able to use his fingers again, it was amazing.
