There are various options available, such as orchid bark, sphagnum moss, perlite, or a combination of these materials. Avoid using regular potting soil, as it retains too much moisture and can lead to root rot.

Repot if necessary: If your orchid is currently in a pot with inadequate drainage or the potting mix has broken down and become compacted, it’s recommended to repot your orchid. Carefully remove the orchid from its current pot, gently shake off the old potting medium, trim away any dead or rotting roots, and repot it in a new container with fresh, well-draining potting mix.

Add drainage materials: If you’re repotting your orchid or want to improve drainage in an existing pot, you can include additional drainage materials. Place a layer of small stones, clay pellets, or broken pieces of pottery at the bottom of the pot before adding the potting mix. This layer helps create space for excess water to drain freely.

Avoid water retention trays or saucers: Do not allow your orchid to sit in standing water or use water retention trays or saucers. These can trap excess moisture and lead to root rot. After watering, make sure to empty any water that collects in trays or saucers.

Consider pot size: Orchids prefer to have a snug fit in their pots, as it helps with stability. However, avoid using pots that are excessively large for the size of your orchid. Excessively large pots can hold too much moisture and lead to poor drainage. Choose a pot that provides enough space for the roots to grow without excessive moisture retention.

Apply a fungicide

Applying a fungicide can help prevent the spread of fungal infections that may contribute to root rot in orchids. Here’s how you can use a fungicide effectively:

Choose the right fungicide: There are various fungicides available on the market, specifically formulated for orchids. Look for a fungicide that is safe to use on orchids and labeled for controlling fungal diseases, including root rot.
