Fertiliser for Moth Orchids


Fertiliser is an essential component of growing beautiful and healthy moth orchids. Without adequate nutrients, these exotic plants will not bloom.

Fortunately, there are a few easy-to-follow tips that can help even novice gardeners maintain the right balance of fertiliser for their prized orchids. When it comes to feeding your Phalaenopsis Amabilis, the key is to use a balanced liquid fertiliser every two weeks during its active growing season: spring through fall.
