Growing Bromeliads
Bromeliads are one of the best tropical plants to grow
in your home. In their native habitat, they are often epiphytic,
attaching themselves by special root s tructures
to trunks and branches of trees and deriving their moisture and
nutrients from the air and rain. They have been commercially
cultivated in Europe for more than a hundred and fifty years, becoming
one of the most popular flowering house plants. Their admirable
qualities include easy care (infrequent watering), a long lived
"flower" (three months or more), and many vivid colors available
(resulting from hybridizing and selective breeding). In fact, they are
often featured in home and garden magazines. Over the past twenty
years the popularity of these marvelous plants has steadily increased
in this country. These exotic looking plants are even appearing in
movie set designs and are being used extensively by interiorscape
designers for long duration color accents.
Inflorescences (flower clusters) rise out of the
center of the plant in colorful clusters above stiff or succulent
foliage. In the case of bromeliads, the showy parts are actually
clusters of waxy bracts that are born beneath each tiny flower. They
can vary from red, pink, yellow, purple, orange or white. Blooms can
last from 8 -- 12 weeks depending on variety and conditions.
After flowering, "pups" or young offshoots will develop around the
base of the plant. When they reach about 3" -- 5" high, they may be
cut off from the mother plant and repotted.
In fact, it is very easy to encourage your plant back into flower next
season. To quote the University of Florida: "Many factors cause
bromeliads to bloom such as plant age, day length, light intensity,
water and temperature. Some bromeliads bloom quite regularly while
others do not. Research on the flowering process has shown that
bromeliads can be induced to flower by exposing them to ethylene gas
(a product of burning wood and leaves and ripening fruit and
vegetables). After exposure to ethylene gas, the flowers appear,
depending on the genus involved, within 6 to 14 weeks. A simple method
that a home gardener can use to start bromeliads' flowering is to
place a healthy, mature plant with all the water drained from its cup
inside a tightly closed, clear plastic bag for a week to 10 days with
a ripe apple. During senescence (aging process), the apple releases
ethylene gas that, in turn, induces the bromeliad to flower."
Plants perform best in diffused bright light, keeping
them slightly moist (high humidity), but in well drained soil. A
bromeliad soil is best, containing fir bark and/or osmunda fiber. Be
sure to keep the cups filled with fresh water.
Fresh Air!
Bromeliads are not only beautiful indoor plants, but extremely
effective in cleaning the air! The Foliage for Clean Air
Council states that many tropical houseplants, including
bromeliads, have the ability to absorb harmful pollutants and clean
our air. They have some air-purifying qualities that can remove as
much as 80% of certain airborne pollutants.
