There are black spots on the leaves of copper coin grass. What diseases does copper coin grass usually get?

1. Disease and insects

Pennywort has relatively few diseases and pests and has strong adaptability, but it is inevitable that it will be attacked by pests from other plants when grown at home. When it comes to diseases and pests, it is important to find the source. Severely diseased plants should be removed, and those with mild symptoms can be properly pruned. Attention should also be paid to spraying pesticides, which can effectively treat the disease.

2. Too much light

The pennywort is a plant that does not like light very much. If the light is too strong, the leaves of the plant will easily be sunburned, and there will be black spots on them, and they may also turn yellow. Generally, you need to place the plant in semi-shade and let it receive scattered light. If it is summer, you must avoid direct sunlight, and in winter you can increase the light appropriately.

3. The temperature is too low

The cold resistance of pennywort is not very strong. Once it is frozen, the plant is prone to poor growth and black spots may appear on the leaves. In winter, be sure to place the plant in a warm place, or cover its upper part with plastic tape, which can also have a heat preservation effect. Poke several holes in the bag to ensure good ventilation and breathability.

4. Fertilization is too concentrated

The copper coin grass has a high demand for fertilizer, but it must be fertilized in small amounts and frequently. If the fertilizer concentration is too high, it can easily burn its roots and cause black spots on the leaves. Usually, you need to use clean water to wash away the fertilizer in the soil. If the situation is serious, you can also change the pot and soil of the plant and place it in a cool place for preservation and maintenance.
