Stenocereus Specimens

I have identified 2 species of Stenocereus in my collection. Both came from packets of Horti mixed cactus seeds. Stenocereus can grow into very large specimens.

Stenocereus thurberi seem to be terribly vulnerable to attack by spider mites. My specimens have not grown all that well, or maybe I am simply neglecting them in favour of other better-looking species. So far, I have not seen a good looking large specimen of this plant in Malaysia.
Stenocereus pruinosus is much tougher. This species is much less susceptible to scarring caused by spider mite attacks. It is damaged only if neglected under extremely dusty conditions for a long time. Scale insects attacks this plant, though, but this genus is not a favourite of scale insects, thank god!

New growth has a waxy layer which washes off in a few months. This can be seen in the picture at left.

I have been phasing out Stenocereus thurberi and keeping a few Stenocereus pruinosus. By 2001, my largest Stenocereus pruinosus is over 1 feet tall. I am not pushing it too hard, as it would be difficult to keep a 5m plant in the garden.
