frosts. Most
evident would be tropical
plants stretched to a cooler
zone.
The term tender(cold susceptible) can be used to describe any plant that
will suffer from
coldtemperatures,
even a
light frost. These plants generally come from
tropical or
sub-tropical regions and need special care when planted out
of their native
. This plants cannot
survive
outside during the
winter when
temperatures drop below 4°C, and must be
overwintered inside before the first
killing frost. In the
north country this can be anytime from mid-September to October.
Tender plants are suited for indoor and requires a minimum
temperature of 10-15°C although some of they may tolerate
occasional short
exposure
to below this level. So, it's also vital to wait until the last
frost date
for your area before to move them outdoors.
