Rot root on San Pedro

[Hofmann]

How do u know whether your San Pedro Cactus has rot root? How dangerus is it for the plant if it has.... will it kill it or will it survive it?

Take the cactus out of the soil and shake the soil of. Check the roots for soft spots. Rotting roots can be lethal to the cactus. San Pedro is also very sensitive for certain insects, which spread by drafts.

Root rot is very nasty. Usually it turns up under conditions of prolonged humidity of the soil. Especially when temperatures are low (beneath 16 °C) rot can start easily at the roots and will go upward and infect the base of the plant...the core of the plant will be next and then........<img border="0" src= "smileys/smiley11.gif">


What to do: If only the roots are infected, remove the plant from the soil and let it dry for about 3-4 days. After this you shoot repot the plant into fresh and rather dry cactus soil.


If the base of the plant is infected (it will turn soft and black) cut the plant 1 cm above the infection with a clean sterilised (70% alcohol) knife. Let the cut dry untill the wound becomes firm and dry (after approximately 2-3 weeks). Repot the cutting in fresh cactus potting soil. Dont water untill the cutting has formed some roots (after about 3 weeks usually)


good luck!
