In July 2014, the San Pedro measured 8 ½" and 14 ½". They are allegedly capable of growing a foot (12") per year. So, in July 2016 they could have potentially reached 34 ½" and 38 ½". However, in March 2016 (20 months later) they only made it to 16½" and 21½". So, the shorter section grew 0.4" per month, or 4.8" per year, and the taller one grew 0.25" per month or 3" per year. At that rate, one or the other could pass my height (6' 1") by 2027!
In October 2025, "Spike" – the San Pedro – measured 7' 10"! Old Spike wouldn't fit back into his winter home, so we cut the top off the tallest segment, and re-potted it, The newly potted cacti is the same height as the original back in 2014.
Let's do the math. The tallest segment of the cacti was 14 ½" in July 2014. In October 2025, it was 7' 10" or 94", so it grew 79 ½" in 11 years, or 7.2" per year. Not as much as the advertised growth of a foot per year, but still impressive.
