How to care for orchids and keep houseplants alive
How to care for orchids. Orchids are a popular houseplant but many people think they are 'difficult' to grow. In fact, they are suprisingly hardy. The main mistake people make is to cover the roots (this applies to the moth orchid, the most common). Their roots are green like leaves because they can photosynthesise, so keep them in a clear, transparent pot and feed with special orchid food.
