The frequency at which you should water your bromeliads depends on a number of factors, including the size of the plant, the size of the container, the humidity and temperature in the room, and the time of year. In general, bromeliads prefer to be kept evenly moist but not waterlogged. It's best to check the moisture level of the soil by sticking your finger into the soil and feel it. If it feels dry, it's time to water. If it feels moist, wait a bit longer before checking again. It's also important to note that different species of bromeliads may have different water requirements.
Why do the bottom leaves of my bromeliad curl up and die?
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 center 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 and wait for the offsets to grow, or simply cut the stem and propagate it if you want to keep the plant.
