Root prone plants
are plants
that are
sensitive to root rotinfection
due to
bacterial or
fungalpathogens.
The problem is particularly serious if the
rhizosphere is kept too
wet, especially in cold
weather.
The Root-sensitivity varies in different
species and
is particularly serious in
drought lovers plants, such as many
cacti and
succulent, especially during the
rainyseason, in
waterloggedsubstrates
and in poor
draining
terrain where the excess of
water removes
much of the
oxygen and creates a favourable condition for root rot fungal
pathogens such as
Phytophthora, Phytium
and bacterial infections
Root prone plants needs very good
drainage
and are sometimes
grafted to eliminate this problem. Another option for
protecting root sensitive species grown in areas where
winter
temperatures are low is the concept of ‘minimum heat’. In this
system some type of heat is employed to keep the soil
temperature at a minimum temperature.
