Orchids: How to Feed, Care & Get Blooming Results

Orchids are stunning and surprisingly resilient when given the right nutrients and environment. Whether you’re growing phalaenopsis, cattleya, or cymbidiums, this guide explains exactly how to keep your orchids healthy, flowering, and thriving—using premium Complete Grow fertilisers.

Which Orchids Need Fertilising?

All orchids benefit from regular feeding—especially during active growth and flowering. Some of the most common varieties grown in Australia include:

• Phalaenopsis (Moth Orchids): Ideal for indoors. Needs consistent light feeding to encourage repeat blooms.
• Cymbidiums: Cool-tolerant and grown outdoors. Heavy feeders—require regular fertiliser through spring and summer.
• Cattleyas: Thrive with warmth and bright light. Feed when new growth appears and during bud development.

Light, Water & Orchid Media

• Light: Bright, indirect light is best. Avoid direct sun, which can scorch leaves.
• Water: Water when roots turn silvery or the potting mix feels dry. Avoid soggy roots.
• Potting mix: Use a coarse, well-draining orchid mix—typically bark, perlite, and charcoal. Avoid soil or dense composts.

Avoid letting water sit in the crown of phalaenopsis orchids, as this can lead to rot. Let the pot drain fully before placing it back in decorative containers.
