Yes. When planting a bougainvillea, do everything you can to maintain the integrity of the root ball, as if it becomes broken apart or too loose, this can cause serious stress to the plant. After the hole is prepared, cut the plastic can apart with a pair of pruning shears and peel back like a banana, and then place one hand above and one hand below and gently lift out of the container, setting carefully in the hole such that the top of the rootball is exactly even with the new soil level you are creating in container or ground. Back fill with amended soil and firm with the palm of your hand. Water well to further settle the soil. If some sections of the planting area sinks after irrigation, add another handful or two of soil as needed. If you have further questions, please feel free to contact us.
