If the plant is mature enough and just doesn't seem to want to bloom, blooming
can usually be triggered by exposing the plant to ethylene gas. The simplest
method for doing this is to enclose the plant in a plastic bag with a ripe
apple. Keep it out of the direct sun for a week. The ripe apple will release
ethylene which triggers a chemical reaction in the plant telling it to stop
producing leaves and start producing a flower spike.
The longer you leave the pups on the mother plant the quicker they will
reach maturity (taking nourishment from mom). Feel free to trim back the
leaves of the parent plant if they start interfering with the growth of
the pup. Alternatively, taking the pups a bit smaller will encourage the
mother plant to throw more pups sooner. It depends on whether you want a
bunch of plants (for bedding or to share with friends) or if you just
want a few that will mature quicker.
Alternatively, if you have a number of evenly spaced pups around the mother,
you may opt to cut away the mother plant as the leaves turn brown
and let the pups remain attached to the base of the mother to form a clump.
Most epiphytic (growing on other plants) bromeliads do well in this loose,
organic medium but terrestrial bromeliads do better in a mix that retains
a bit more moisture. Most terrestrial (growing in the soil) bromeliads do
not have leaves that form holding tanks to supply their need for water.
These bromeliads include the succulent Dyckias and Hechtias,
the grass-like Pitcairnias and the pineapple.
Some bromeliads (particularly the grass-like Pitcarinias) can be
"pushed" to grow quicker by adding extra fertilizer. Most, though, will not
benefit by excessive fertilizer which will tend to make the plants "leggy"
(excessively long leaves) or, in the case of those with colorful foliage
(like Neoregelias), it will diminish the colors turning the plant green.
For "air plants" like Tillandsias which are grown attached to a
piece of wood, cork or sometimes nothing at all, they should be misted a
couple of times a week and even more frequently during the dry winter season
when grown indoors. As an alternative to misting, plants grown indoors may
be dunked or soaked in water for a few minutes to rehydrate the plant. Make
sure to drain away any excess water caught between the leaves as this may
promote rot.
Pay attention to your plants and they will tell you if they are unhappy. If
a plant is being grown in too little light, it will often lose the bright
colors that it had when you bought it. In addition to turning greener (adding
chlorophyll) to make the most of the lower light level, many plants will
start growing much longer leaves increasing their surface area to compensate.
If your plant starts getting "leggy", try moving it (gradually) to a brighter
area. The plant should respond by regaining its color and "tightening up" to
form a dense rosette with shorter leaves.
On the other extreme, too much light can be the culprit if the plant's color
starts fading or "bleaching". If brown, sunburned spots start appearing on
the horizontal portions of the leaves, it is a clear indication that the plant
is getting too much light. Sometimes a plant that should be able to take more
light fades or burns when placed in a sunny area. The plant might have been
living in dimly lit conditions before you obtained it. You can work it out
into brighter conditions in stages to acclimate the plant.
Another cause might be excessive fertilizer. The nitrogen, potassium and
phosphorous salts contained in fertilizers can build up with repeated
applications and precipitate into damaging crystals just like hard water.
To avoid this problem, don't over-fertilize and flush the water in the cups
occasionally to rid them of the salt buildup.
