I have one a few feet from my deck. I've cut it off near the ground several times in 6 or more years, but it seems to come back w a vengeance each time. We had a huge one in the backyard @ the last place we lived we loved the shade and the smell of the flowers in bloom. My wife is very afraid of bees, but I don't think she's ever been stung........anyhow the tree has grown about 16' tall and seems healthy. It is growing over the roof. I was thinking I could train it to grow over the deck and provide shade and ambience to the back deck and I have already put strap on it and pulled it over the deck where it branches look like they will about perfectly spread over it. I suppose if it doesn't grow right or wanes I can just cut the tree down again. Any advice about this idea and the mimosa tree is appreciated.
