1. Why are there brownish welts filled with liquid on the underside of my Bromeliad?
Rust disease causing the brownish welts filled with liquid on the underside of leaves in Bromeliad are due to rust fungi. overwatering the plant causes rust fungi to grow on the plant. Make sure the drainage hole of the pot is not blocked, let the soil air out. Remove the affected leaves and treat the plant with a fungicide.
2. Why are the leaves at the base of my Bromeliad turning brown or soggy?
The basal leaves of the Bromeliad can turn brown or soggy as an indication of either root rot or heart rot. Root cause can be cause either by over-watering or because of the soil remaining excessively damp because the draining hole is blocked or owing to the type of soil used. Heart rot happens because of fungal infections and can be treated with fungicide.
3. What is the chalky substance on the leaves of my Bromeliad?
When the water used for the Bromeliad is loaded with minerals because it is not distilled water, that mineral builds up in the leaves where the water is stored, causing the chalky residual when the water evaporates from the leaves.
