What is the cause of black tips on orchids?

1. Too much light

Reason: Orchids are very afraid of direct sunlight. Too strong light can easily burn its leaves and cause the leaf tips to turn black.

Solution: Move the orchid to a semi-shaded location, or provide shade during the summer. It should be noted that long-term lack of light is also detrimental to its growth and affects the differentiation of flower buds. Therefore, it can receive light every morning and evening, and the pot should be rotated regularly to ensure that it receives light from all sides.

2. Air Drying

Reason: Orchids grow best in a humid environment. If the climate is too dry and the temperature is very high, the leaves will easily lose water and turn black.

Solution: Place the orchid in the shade. At the same time, sprinkle water around to increase the humidity of the environment. The evaporation of water can also lower the temperature. You can also spray water on the leaves, but not too much to avoid water droplets entering the leaf sheath and causing internal rot.

3. The temperature is too low

Reason: Orchids prefer warm climates. If the temperature is low and stays below 0℃ for a long time, the plants will easily be frozen, causing the leaf tips to turn black.

Solution: Keep orchids warm in winter and control the temperature between 10-15℃. If the indoor temperature is not high enough, you can cover it with plastic film. Spray some water before covering it to moisturize the leaves.

4. Waterlogging and root rot

Reason: If you water the orchid too much, the soil in the pot is too moist or there is water accumulation, it is easy to breed bacteria and make it sick, which will cause the leaf tips to turn black.

Solution: If there is water accumulated in the flowerpot, you need to drain it first. Then remove the plant from the pot and check for root rot. After cutting off the rotten roots, apply carbendazim for disinfection. Replant with dry new soil and do not water after planting. Place it in a cool place and wait until it resumes growing before watering it again.
