Q: Any instructions for planting a bougainvillea in Green Valley? I will purchase a potted plant and put it in a hole in the ground.
A:Β Bougainvillea is a tough plant and digging a hole that is as deep, but not deeper than the roots in the container is the main thing. You can set the container in the hole once you think it is deep enough to make sure. The main things to watch out for when selecting a site are protection from the cold and proper irrigation. In Green Valley, there is a greater chance of frost damage, and this plant can die back to the ground. So choosing a site that is somewhat protected or close to hardscaping that can radiate heat is helpful. In extreme cold, you may have to cover it like we do with citrus. Also this plant doesnβt need much water but it does need some, especially to get established, so make sure there is a way to get drip irrigation or hand watering to the plant.
