In transplanting a 6 foot saguaro the tap root was knocked off. In fact,
all the roots were knocked off. We were told to allow the "stub" to air

any plant that has a tap root is essentially fatal, and that burying the
crown will ensure a slow death if the root damage doesn't, but this
landscaping "expert" assures us the cactus will eventually grow new
roots. He also said it should be apparent within 6 weeks if the cactus
isn't going to survive (appearance of shriveling), while my reading
indicates a saguaro's slow death can take up to five years. Would anyone
in the group have experience with this and care to offer a comment? A
saguaro of this size is outrageously expensive and I have a feeling the
landscaper is trying to pull a fast one on us.

Cacti are monocots and do not have taproots. Just be sure that the soil
drains very well and that you don't overwater it.


Carnegiea gigantea
"A tap root extends downward to more than 2 feet (60 cm). The rest of
the extensive root system is shallow, as is the case for most
succulents. Roots are rarely more than 4 inches (10 cm) deep and radiate
horizontally about as far from the plant as the plant is tall."

Is it not a true tap root?
