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 depends on how big you want the bamboo to grow. Dedicate at least 3 feet by 3 feet for the Clumpers (12 feet circumference), and 3 feet by 10 feet for the Runners (26 feet circumference), to get reasonably close to mature height. The more space the better.aller running types, like Phyllostachys, usually grow 3-5 feet in height per year. Older, more established plants, usually at least 3 years in the ground, will grow faster than newly planted ones. Placement and care will influence how fast and tall a bamboo will grow.
