Bromeliad’s are one of life’s simple pleasures…lovely to look at, easy to grow, nothing to worry about. However, once they finish blooming, everyone asks, “How do I get them to re-bloom?” “How do I take care of them?”
Culture:
It’s best to use purified water, especially for soft-leaf types like Guzmanias. Do not use water from a softener.
Let the plants dry out between waterings. It is okay if the soil on the bottom of the pot still is a little damp, but the surface should be dry to the touch.
Water the plant by pouring directly into the “cup” or “tank” formed by the center leaves. The tank is an evolutionary adaptation that acts as a reservoir, providing an emergency supply of water and nutrients. Continue pouring after the tank begins to overflow, allowing the excess to spill out and moisten the soil below.
Direct light on a sunny day is far too intense for most bromeliads, including Aechmeas and Guzmanias, the two most popular types. Direct sunshine can exceed 10,000 foot-candles; the ideal light level for bromeliads is generally around 1,800 foot-candles. If you don’t have access to a light meter, simply look for an area that is somewhat shaded and protected from long periods of hot, direct sunlight.
Scientific studies suggest bromeliads can help improve indoor air-quality as you sleep. In the photosynthetic process, most common indoor plants remove carbon dioxide while emitting oxygen and water vapors during the day. But research indicates that bromeliads behave differently during the day / night cycle, releasing oxygen and removing air pollutants at night. Data collected by the Plants for Clean Air Council suggest that when combined with foliage plants, bromeliads can help provide around-the-clock indoor air purification.
Re-Blooming:
Bromeliad blooms are a wonder of variety and longevity. They come in an astounding array of colors and shapes. Some remain tucked inside the rosette of leaves, while others grow into plumes reaching two or more feet in length.
Numerous factors contribute to bromeliad blooms: time, light and water are just a few. One of the most important variables is temperature, with a minimum requirement of 50 degrees
Many of the more popular types of bromeliads, including Guzmanias, Tillandsias and Vrieseas, bloom naturally during the spring, summer and fall months. Guzmanias require purified water and more humidity than other types.
It is possible to prematurely force a bloom by exposing a bromeliad to ethylene gas, a natural byproduct of decomposing organic matter. For the home enthusiast, take a slice of an apple and place it at the bottom of the plant or tuck it into one of its leaves. Commercial products such as Florel, often used to ripen tomatoes and other fruits and vegetables, have successfully been used to produce bromeliad flowers.
