Cleistocactus

Three stemmed cleistocactus straussii added 16" on shortest stem this summer!

Last year I was trying to push my Cleistocactus as much as possible by fertilizing a lot. It did grow a lot adding about a foot on each of 2 stems and near the end of summer beginning to sprout a 3rd stem. I theorized then that probably the tallest stems would begin to grow less and shorter stems would grow more as the plant reached it's genetically controlled maximum height. This year I barely fertilized the plant at all almost ignoring it. The result was that the tallest stem reached 61" high adding only 3" this year. The second tallest stem added only 5" to finish at 55" tall. The shortest stem however grew a phenomenal 16" this year to finish at 23" in height!
