Why are the tips of gardenia leaves black?

1. Causes

1. The use of water is the main reason why the leaves of plants turn black. The water should not be too much nor should it be kept without water for a long time.

2. The use of fertilizer is also crucial. Do not use raw fertilizer or overly concentrated fertilizer. Doing so will cause the plant to grow poorly and cause the leaves to turn yellow or even black.

3. When encountering strong sunlight, do not expose the plant to the sun for a long time, as this will cause the water in its body to evaporate quickly, resulting in dry tips and burnt edges.

2. Solutions

1. If the leaves have turned black, you need to trim off the diseased areas and then water it. When the water overflows, it means that it has been watered well. The benefit of doing this is not only that it can dilute the excessively concentrated fertilizer used by the plants, but it can also replenish water in a timely manner.

2. You can place the plant in a windy and unobstructed place for maintenance. In summer, avoid direct sunlight and block about 50% of it. Except for this season, in other seasons you can give it gradual exposure to sunlight, for about 2 to 3 hours.

3. This plant needs some iron elements added to it. You can put an iron nail in the soil where the plant is planted.
