1. Raise the temperature1. Reason: The green ivy does not have a strong cold resistance, so it cannot grow in a too cold environment for a long time. Otherwise, it may be frozen and the stems and leaves may turn black. 2. Treatment method: Place it in an environment of 10℃. Cut off the stems and leaves that have turned severely black, then slowly care for it and wait for it to recover. 2. Remove from the pot and replant1. Reason: If the soil in which the plant is grown is not breathable enough, or if it is watered too many times during cultivation, it may cause root rot. The black rot at the root will gradually spread, causing the stem to rot. 2. Treatment method: Remove the plant from the pot, cut off the rotten roots and the severely blackened parts of the stem, then change some flower soil and replant it. If it is severely rotten, it needs to be pruned and replanted. 3. Spraying to remove bacteria1. Reason: If it is infected by some bacteria and disease occurs, the stems may turn black. 2. Treatment method: Remove it from the pot, cut off the blackened stems and leaves, then soak it in a fungicide for 20-30 minutes, take it out to dry, and plant it in new soil. And during the subsequent maintenance process, spray the disinfectant once every 10 days or so to prevent recurrence. |
