Moso bamboo spreads using both asexual and sexual reproduction. The most common and well known for this plant is asexual reproduction. This occurs when the plant sends up new culms from underground rhizomes. The culms grow quickly and reach a height of 90 ft or more (depending on the age and health of the plant). In mature individuals, the culms in young plants grow taller and wider in diameter as the general plant reaches maturity, but once the individual culm stops growing it will not grow again. P. edulis also flowers and produces seed, and it does so every half century or so, but it has a sporadic flowering nature and there are always a few individual plants in flower somewhere.
I have done some testing on growing moso bamboo and documented the process in the my youtube video below which I feel proud sharing with you guys. Sadly it didn't turn out what I had expected but there could be many reasons behind the failure. The soil was perhaps too acidic or the seeds received were not fresh. However, I will not be giving up nor surrender attempts in planting bamboo. I also have to admit that the video shows the progress after four weeks, its advisable to wait 5 to 6 weeks for good results though. Thank you for watching the video and please take your time to subscribe to my youtube channel. I like to post videos on gardening from time to time and share success and failure stories with the audience.
