DALY: Houseplants brighten the indoors during winter  Many
people have houseplants in their homes and businesses to enhance
the aesthetics of these indoor environments. Their presence
complements other interior decorations. Also, studies have shown
houseplants reduce indoor air pollution. In a sense, they help
us stay in touch with nature during the dead of winter. Since
most house plants are tropical, they do not tolerate freezing
temperatures and many suffer when temperatures drop below 50.
Thus, they need to be brought indoors during cold weather.
Keeping houseplants healthy and attractive during the winter can
be challenging as a result of the lower temperatures, humidity
and light levels which are common to interior environments.
Different species of plants have differing requirements. Some
plants, especially succulent plants like aloes and cacti,
require significantly less water than peace lilies and African
violets. Ferns prefer lower light levels, but wax begonias need
higher amounts of light. Knowin
