How to Care for a Phalaenopsis Orchid: 6 Expert Tips to Get It Flowering Again

Has your orchid finished flowering and now you're not sure what to do with it?

Don't worry—you don't need to throw it away! With the right care, most orchids will flower again year after year. Here are our favourite tips for keeping your orchid healthy and encouraging another spectacular display.

Tip 1: Remove the moss

Many orchids sold in stores are potted in sphagnum moss to help them cope with transport and long periods on shop shelves. While it serves a purpose initially, it's often not the best long-term growing medium.

Phalaenopsis orchids are epiphytes, meaning they naturally grow attached to trees and rocks rather than in soil. Their roots need plenty of airflow and light. Moss can stay wet for too long, reducing airflow around the roots and increasing the risk of rot.

Tip 2: Use a clear container

Did you know orchid roots can photosynthesise? That's why Phalaenopsis orchids often do best in clear pots, where their roots can receive light and you can easily monitor moisture levels.

If you'd like something more decorative, place the clear pot inside a glass vase or stylish outer container.

Tip 3: Try LECA

LECA (Lightweight Expanded Clay Aggregate) is one of our favourite growing media for orchids.

The clay balls provide excellent airflow, allow light to reach the roots, and don't stay soggy like traditional potting mixes. They also give the roots something to anchor onto, creating conditions that are similar to the orchid's natural environment.

Tip 4: Don't cut the flower spike too soon

Once the flowers have finished, resist the urge to cut off the entire flower spike.

Leave at least three nodes on the stem, as the plant may produce a secondary flower spike from one of these nodes. Even if it doesn't, the stem continues supplying stored energy to the plant while it remains green.

Once the spike has turned completely brown and dried out, it can be safely removed.

Tip 5: Feed your orchid

An orchid-specific fertiliser is one of the easiest ways to encourage healthy growth and plenty of flowers.

These fertilisers are formulated with the right balance of nutrients, including higher levels of potassium to support flowering. Feed regularly during the growing season, following the instructions on the label.

Tip 6: Don't overwater

Overwatering is one of the most common reasons orchids fail.

If you're growing your orchid in LECA, keep only a small amount of water in the bottom of the container so the LECA can wick moisture upwards. The roots should never sit submerged in water.

A healthy orchid prefers to dry out slightly between waterings rather than remain constantly wet.
