Fall update on the inground bamboos fully leafed out and making rhizomes

My bamboos have finally reached their full glory as they become fully leafed out in the fall, and become energized in preparation for shooting season next year which should produce shoots that rise above 20 feet if I'm lucky.

Phyllostachys edulis moso bicolor: This one is getting pampered more than any other bamboo since the soil has been prepared with hundreds of pounds of organic manure with a mixture of manure, compost, worm castings, scraps, and topped with grass clippings. I added the roofing rubber to keep the area insulated so rhizomes can be encouraged to spread.

Phyllostachys atrovaginata: This bamboo doesn't usually produce that many shoots, but it upsizes the fastes out of all my bamboos so far and has very good hardiness. This bamboo may have the largest rhizomes sometimes as thick as an inch in diameter.

Here are a few atrovaginata rhizomes turned upwards to turn into divisions.

Phyllostachys Bissetii: This is not doing much, however it's producing perfect size divisions for me.

Phyllostachys propinqua beijing: This bamboo is perhaps the most upright of all of the with slender tall culms and seems to be a slow runner in comparison to the rest of the phyllostachys species.

Phyllostachys aureosulcata yellow groove: Not much change from last year, but I completely neglect this one, and it may be in need of a thinning as well.

Phyllostachys Dulcis: This one seems to have arching culms, and doesn't produce too many of them either. It also doesn't seem to run very fast.

Phyllostachys nigra: The leaves are still a bit yellowish from being in a pot for too long but it seems to be enjoying it in it's spot in the ground as rhizomes are already spreading out around 2 feet in all directions.

Phyllostachys Kwangsiensis: This is my largest seedling out of the kwangsiensis batch and it seems to be shooting nonstop, but it's also still in it's clumping form.

Phyllostachys aureosulcata spectabilis: This was from a 1 foot long rhizome back in spring this year and it has since grown into an established plant, spreading it's own rhizomes out already.

Phyllostachys parvifolia: This is perhaps the most aggressive and one of the fastest to upsize bamboos that exist as this used to be a couple of twigs less than a foot tall 2 1/2 years ago however it has turned into a monster.

Here are some of it's rhizomes turned up which are turning into nice divisions.

Zebra grass: Not really a bamboo, but it's starting to take up more and more space each year as it's clump keeps expanding.
