Tropical plants and cold (Part 1)

November 26th, 2007

Tropical plants are called tropical, because they grow in tropics where it is always warm. However they are frequently grown in “not tropical” conditions, for example, in an apartment. Transportation of plants in the frosty winter is also not tropical conditions. Sudden decrease of temperature almost to zero point (in Florida it also can happen - two nights in a year) or a cold draft on the glazed loggia also are not tropical conditions.

The simplest way to determine when tropical plants feel cold is to look in a mirror at your nose: if it feels cold, the same feel your plants.

Some tropical plants can survive short-term decrease of temperature, others – can not. For example, the mature jackfruit can survive fall in temperature to zero point for some hours (but young plants will be killed thus almost at once). And its nearest “relative” a breadfruit tree badly tolerate fall in temperature even to +5 C – a huge plant in tropics, but nevertheless …

Tropical plants, unlike the others (even subtropical), “are designed” to actively grow within the whole year. They do not have such dormant period when the plant prepares for colds - shed their leaves, the trunk covers with a thick bark, and vital functions are almost at zero point.
