I have a friend wondering if she can Root Bougainvilla cuttings, and if so, what time of year and how?
I tried searching the net, but haven't found much,
Yes they will root.
Cuttings from mid-winter to early spring, keep soil mixture moist, better with bottom heat.
I'd use rooting hormone too.
I've had better luck with hardwood cuttings than with softwood. Otherwise, same as for lazygardens.

I'll second that, hardwood seems to be the luck of the draw with me.
I'll add my voice to the chorus. I've had success rooting them from spring through early summer and like the others mentioned, hard wood seems to work best. I actually like hard, twiggy growth that's very skinny for rooting. My success rate has never been high, probably between 25 and 33% or so, but that's been enough. Mine rooted in water, potting soil, and perlite.
Let us know if your friend gives it a try and how it works out.
I've traded bougie cuttings on gardenweb because they are easier to root rather than transplant. Bougies are big with bonsai gardeners. I'm surprised you didn't find any information.
