I have a brug in my greenhouse that has gotten a bit out of hand. It is a large single pink, really quite pretty, but the tag was lost and I tossed it in a rubbermaid container with some random pots I had dumped out. Predictably it rooted. Less predictably it found a crack in the container and took hold in the ground over the winter, becoming a monster.
At this point the trunk is about 10" across at the soil line and the plant scrapes along the top of my 13' geodesic dome greenhouse. I have to prune it several times a year because it invades the ceiling fan in the center of the roof and reaches out across the entire half of the greenhouse if I let it (it is rooted on the Northern side of the dome). When I tip prune to shorten the branches it tends to pop out fast growing suckers that shoot for the ceiling. They sometimes get to 2" in diameter or more before I notice them. These cut quite easily in the first year, being very tender.
My question (besides any advice you have on wrangling this beast) is if anyone has experience trying to root or layer such large branches. I'm always cutting them off, it seems, and it would be nice if I could plant them out and enjoy them in the yard once in a while. A few times I've stuck them in a pond and had them stay green for months, but no roots or new growth formed. The wood is still tender (what I would call semi-hard) usually.
