Detailed explanation-1: -Bromeliads are a type of plant called epiphytes, which means that they draw moisture from the air and don’t need to be in soil to survive. While their roots can draw water and nutrients, they typically serve as a plant’s ‘anchor’, attaching and holding it place.
Detailed explanation-2: -Soil. Bromeliads grown indoors thrive in fast-draining potting soil that holds moisture but drains well. A mixture of two-thirds peat-based soil and one-third sand is often ideal. You can also use orchid mix, charcoal, or soilless potting mix.
Detailed explanation-3: -Most bromeliads, about 75 percent, are epiphytes, meaning they can grow on trees or other wood objects (wood slabs, stumps, driftwood); they don’t need soil. The bromeliad does not harm the tree; it merely uses its roots to anchor itself to the tree.
