CULTURAL INFORMATION
FOR GUZMANIA BROMELIADS
Of the more than 150 species of Guzmania, nearly all are
tank-forming and although some may have colorful leaves, most are shiny dark green.
Their bloom spikes or inflorescences are their most desirable asset and hold
their color long after flowering. These may be compact heads or elongated
spikes resembling fountains. Most guzmanias grow in tropical forests in wetter,
cooler, shadier habitats than most other bromeliads.
LIGHT: Because of the lower light requirements, guzmanias are an ideal
indoor bromeliad. If placed outside, be sure that no direct sun reaches them.
TEMPERATURE: Guzmanias must be protected from frost or
freeze and many do not care for extreme summer heat.
WATER: Water quality is very important for guzmanias. They do not care
for hard, alkaline or salty water. Flush central reservoirs of bromeliad at
least once a week. Avoid hard water; it can cause spotting of the leaves.
Collected rain water is beneficial.
AIR: All bromeliads like good air
circulation. If a bromeliad is placed in an unshaded window, it will likely
burn because there is no air circulation to dissipate the heat.
FEEDING: Use a dilute solution ( 1/4 strength) of
a high quality, acidic, water-soluble fertilizer and drench the potting medium,
foliage and central reservoirs with it.
There are several
formulation of DYNA-GRO fertilizer that we highly recommend. Guzmanias can also
be fed by mixing a slow-release fertilizer into the potting medium. Beware of
copper and boron which are toxic to bromeliads. Your fertilizer should have
none or no more than trace amounts of these micronutrients.
PROPAGATION: In most bromeliad species, the plant you
see blooming now will not bloom again, but begins a reproductive cycle that
should produce multiple plants that should mature within approximately one
growing season. The 'pups' will draw nourishment from the mother as she
gradually declines. When the 'pup' is one-third the parent's size or when it
begins to get crowded in the pot, it can be removed by gently twisting or
cutting it away from the mother. Be sure to leave enough stem to anchor it when
it is potted. Most guzmanias grow best as single plants to allow their
beautiful symmetry to be appreciated.
POTTING: Don't use pots larger than necessary; most guzimanias grow
nicely in 4" to 6" pots. Any potting mix is acceptable as long as it
is acidic and holds moisture yet drains quickly. It should also be sufficiently
firm to hold the plant steady.
