@TooCoys you southerners are always swapping common names. It's probably taeda. In the north long leaf pine is palustris, which starts out with a few years in a "grass stage". I think taeda must be the easiest pine to sprout if anyone cares to try this project and wants my two cents.
Also, congrats on owning a yacht. All I have is a two person river rat tube
This style is very short lived. It happens rarely in nature. The seedlings will compete and most likely kill each other off. Or after it has been enjoyed for as long as possible, perhaps the seedlings can be pulled out and potted up?
