Rot prone [ Botany - Horticulture ]
Synonym: Susceptible to rotting

Dictionary of botanic terminology - index of names

  Of a plant or succulent plant tissue having a tendency to softer, discolour, and often disintegrate as a result of fungal or bacterial infection.    Rot typically results from damp conditions.  
The cultivation of rot prone plants  (and especially root prone plants) need particular care.
Most succulents and cacti that came originally from very dry environments are considered to be more or less rot prone, this plants grow wild in areas characterized by good drainage, excellent ventilation, high temperature with limited precipitation and intense solar radiation. But the condition of cultivation in temperate and humid zones are very different and not optimal for many of this plant which proved to be extremely susceptible to any excess of moisture in the substrate and in the air too.
First of all plants that are rot prone should be grown in a very porous and draining compost, also they need particularly  watering cares: during the growing season it is necessary  to let the compost dry completely between two successive watering, while during the winter rest season - especially with low temperature - they need to be kept completely dry. Underpot in smaller containers which have excellent drainage is one of the most effective growing practice.
It is also very important to ensure a good ventilation and a good exposition.
For outdoor cultivation raised beds would increase the long-term health of the planting,
Spraying a systemic fungicides especially at the beginning of the growing season and before the starting of the winter rest may be required to keep plants healthy particularly when environmental condition are not optimal.
