When Should You Repot a Phalaenopsis Orchid?

Phalaenopsis orchids should generally be repotted every 1 to 2 years, or whenever the potting mix begins to break down. Old bark retains too much moisture, reducing airflow around the roots and increasing the risk of rot.

Signs that indicate that it is time to repot your orchid include:
• Potting mix that stays wet for too long or smells musty
• Roots growing heavily over the edge of the pot
• Dead or rotting roots
• The plant becoming unstable or outgrowing its container

The best time to repot is after flowering, when new roots and leaves are beginning to grow. Remove old potting material and cut away dead roots.

Orchids don't like to be overpotted so choose a pot that fits the roots and use a fresh orchid bark mix designed for good drainage and airflow.

Water your orchids with water — not ice!

Most orchids are tropical plants and do best with room temperature water. Ice cubes may be convenient, but over time they can stress the delicate roots of orchids.

Instead, water thoroughly, let excess water drain away, and allow the potting mix to dry slightly before watering again. Your orchids will thank you with healthier roots and better blooms!
