Plant size and rate of growth is a direct function of root
development |
 |
|
If you want a large San Pedro you have to allow a
large root system to spread out. Once planted in the earth these
cacti may reach 12 to 14 feet tall (mine do) but winter wind
storms often break off the tallest limbs. If you container grow
your cacti you'll need ones designed for trees. Nurseries and
garden centers sell them. |

This year old plant still has thin ribs. The flabby, wrinkled
appearance indicates that the cutting is not filling out with
water. A close look indicates too many root buds with
insufficient fine root development. The small pot this was in
probably dried out frequently. Solution? Repot in a larger container with fresh soil and see
how it grows this year. |

Below: Excellent fine root growth and development in this
year old cutting. To grow vigorously it needs a larger pot with
fresh soil. First I broke up the outer roots that were bound up.
I do this by
ripping them apart. |
