1. The temperature is too low1. Reason: If the orchid is kept in a very cold environment for a long time, its leaves may be frostbitten and black spots may grow. 2.

If the maintenance environment is poor, it may be infected by some bacteria and become diseased. This may also cause dark spots to appear on its leaves. 2. Treatment method: Place it in a well-ventilated place and use scissors to cut off all leaves with diseased spots. After that, spray it with fungicide every 3-5 days until it recovers. 3. Excessive watering1. Reason: In an overly humid environment, its root system may be waterlogged, causing it to grow poorly and causing black spots to appear on its leaves. 2. Treatment method: Remove it from the pot, cut off the roots that have turned black, and then plant it in new flower soil for maintenance. |
