Unless you want a mixed grove or the tallest species eventually taking over you might want to put down a trench or barrier between each species because they look close enough to intermingle within the 1st growing season.

Anyways as long as you keep them well watered and mulched, they should really fill in next spring after they have spread their rhizomes.

I'm still concerned about those utility lines overhead. Are they over the bamboo? How high are they? Don't be surprised if the utility companies start pruning your bamboos for you at some point if they even think that they'll touch the lines.

The power lines are behind the bamboo. The lines going across are for cable tv. If they try to do anything about the bamboo because of those I'll make them move them somewhere else. I drove down the alley and there are trees up in the lines in other areas so I'm not too worried about it. They were will always be more bamboo coming up ;)

Congratulations. You're much more successful with that ambitious project than I expected. It's really hard to do big divisions and have them thrive like that, especially when you're new to this.

Thanks but I'm chalking it up to beginners luck and excellent advice on when and how to dig. I'm really amazed. Next spring should be very interesting

I have another black bamboo shoot! Incredible.
