I have a trellis (Cairo Egypt) that I would like my bougainvilleas to completely cover. The trellis is 2 meters in width and 4 meters in height. I planted 4 bougainvilleas each apart by 0.5 meters. However I’m not sure now how it would cover the entire trellis. I want it to be very dense, so I have two options I guess:
- plant more bougainvilleas with more density, so maybe between each two bougainvilleas I already planted I add one more, but I'm not sure if 0.25m between each plant is a safe distance
- or after the bougainvilleas reach out the 4 meters height, I try to twist it to 180 degrees so it continues spreading in the other direction
The idea here is to have a wall of bougainvilleas, completing covering what’s behind it.
