What is what to do when orchid stem turns brown?

Here's information about what to do when an orchid stem turns brown:

A browning orchid stem is usually a sign of a problem. The best course of action depends on why the stem is turning brown and where on the stem the browning is occurring.

• Check for Overwatering/Root Rot: Overwatering is a common cause. Brown, mushy roots are a clear indicator. If you suspect this, stop watering immediately. You might need to repot your orchid in fresh, well-draining orchid mix. Cut away any mushy, rotten roots with a sterile tool.

• Natural Aging (Flower Spike): If the flower spike (the part that held the flowers) is turning brown after the flowers have finished blooming, this is perfectly normal. You can trim it back to just above a node (a small bump on the stem) or all the way back to the base of the plant, depending on the type of orchid and your preference.

• Sunburn: If the stem is brown and dry, especially on the side facing the sun, it could be sunburned. Move your orchid to a location with indirect light.

• Disease/Fungal Infection: Brown spots or spreading discoloration could indicate a fungal or bacterial infection. Remove the affected portion of the stem with a sterilized cutting tool. Apply a fungicide if needed. Proper air circulation is important to prevent fungal issues.

• Stem Rot: This is a serious problem, often caused by standing water in the crown of the plant. If the stem at the base is brown, mushy, and rotting, the plant may be difficult to save. Carefully remove any affected tissue. Improve air circulation and avoid getting water in the crown.

• Fertilizer Burn: Excessive fertilizer can damage roots and stems. Flush the potting mix with water to remove excess salts.

General Tips:

• Sterilize your tools: Always use clean, sterilized cutting tools to prevent the spread of disease.
• Provide good air circulation: This helps prevent fungal and bacterial problems.
• Avoid overwatering: Allow the potting mix to dry out slightly between waterings.
• Provide adequate light: Orchids need bright, indirect light.
• Monitor your orchid regularly: Catching problems early is key to successful treatment.
