Light: the plants prefer well-lit, bright windowsills, but not direct sunlight.
Water: it's enough to water these plants through the soil weekly during the growing season and reduce watering during the winter rest period. Never let the plant rest in standing water.
Fertilizer: Bromeliads are not heavy feeders. During the growing season, use a Grow liquid fertilizer.
Bromeliads are beautiful foliage plants. In general, bromeliads need a fairly specific set of conditions to bloom—and these conditions vary from genus to genus. Their bloom cycle is affected by day length, temperature, humidity, water, and feeding.
While it can be difficult to accurately replicate the conditions any particular bromeliad needs to bloom, some research has shown that the plants can be forced to bloom by exposure to ethylene gas.
If you want to force your plant to spike, place it in a tightly closed, clear plastic bag for up to 10 days with a ripe apple. The apple will give off ethylene gas as it decomposes. Make sure any water is drained from the bromeliad's central cup before attempting this.
