It is important to avoid sun through glass as this can scorch the leaves of tropical plants.
Tropical plants require a humid atmosphere. Mist plants daily, or, better, place on a tray of damp gravel, expanded clay granules (Hydroleca) or recycled lightweight aggregate (Hortag).
Plants grouped together will create a humid micro-climate around their leaves.
Avoid overwatering as this can lead to root death and collapse of the plant
Let the surface of the compost dry a little before applying more water at room temperature. Allow the plant to take up water as it is needed or allow excess to drain away.
Do not let the plant sit in water- make sure there are draining holes in the pot. Including a small amount of gravel inside the pot (at the base) before repotting is also another way to promote the health of the root system.
