The bottom leaves of a bromeliad curling up and dying is a natural part of the plant’s growth cycle. As bromeliads grow, they produce new leaves from the centre of the rosette, and the older leaves at the bottom will slowly turn yellow and die off. This is a normal process for bromeliads and is not an indication of a problem.
However, if the curling and dying of the leaves is accompanied by other symptoms such as brown or black spots, wilting, or a mushy texture, it could be a sign of a pest or disease problem. Additionally, if the leaves are curling and dying off too quickly, it could be a sign of over-watering or poor drainage, which can cause the roots to rot. It’s important to check the moisture level of the soil and make sure that the plant is not sitting in standing water.
It is also important to note that as bromeliads only bloom once in their lifetime and after that, the rosette will slowly die off, this is normal and you can remove the rosette once the pup has grown to over one third the size of the original mother plant.
Bromeliads, in general, do not die after they flower. Most bromeliads will bloom once in their lifetime, and after that, the rosette or the main part of the plant will slowly die off, but it will continue to produce pups that will grow and take over as the main plant.
The mother plant will still be alive and continue to produce pups, which can be removed and propagated when they reach about one third the size of the mother plant.
It’s important to note that the blooming time of a bromeliad is highly variable between different varieties of bromeliad. It can take months to many years. For example an Alcantarea can take up to 15 years to flower.
