Soil is an essential component of any successful garden, especially when it comes to growing Phalaenopsis orchids. These orchids are native to tropical climates and require well-draining soil that can retain moisture and provide enough nutrients for the plants to thrive.

To achieve this, gardeners should opt for a loose, soil-less potting mix specially formulated for orchids that contains ingredients such as bark chips, moss and perlite. This mixture will provide air pockets in the soil while at the same time allowing water to move through the roots quickly so they don’t become waterlogged.

Additionally, it’s important to use pots with plenty of drainage holes so excess water can easily escape without stagnating around the roots. Finally, adding worm castings or other organic fertilisers may help boost nutrient content in the soil and ensure optimal growth over time.
