Re: Natural, Homemade Flea killer Reply Contact. sprinkle some salt on the carpets, and on furniture, let it set for about 2 days, then vaccuum and put down more salt. We had this problem a couple of summers ago and a neighbor told us about the salt and it worked. Was cheap too!
Growth Rate. In the ground, black bamboo grows 3 to 5 feet in height every year, eventually reaching heights of 20 to 35 feet. Container-grown plants, however, typically reach only one-half to three-quarters of their normal size.Running bamboo spreads at a rate of 3 to 5 feet per year.lack bamboo (Phyllostachys nigra) is a tall, attractive, black-culmed bamboo grown in U.S. Department of Agriculture plant hardiness zones 7 through 10.
It is most definitely a spreader (perhaps not AS aggressive as aureus--Golden Bamboo--but a spreader nonetheless). Not sure if there exists a tropical bamboo with dark, or black culms (that may be a clumper), but it would have to be in a different genus (i.e., not phyllostachys).
