How to Care for Black-Eyed Susan

1. Maintenance methods

1. Temperature: We can also see from its place of origin that it requires a higher temperature, generally above 20 degrees. Only if the temperature is suitable can it bloom all year round. Otherwise, not only will it not bloom, but its health will also be affected.

2. Light: Black-eyed Susan also likes light, and whether there is sufficient sunlight will have a great impact on its flowering. Generally speaking, shade is only needed when encountering very strong light, and the rest of the time it can be placed in a sunny place. In winter, good sunlight will also help it survive the winter, and full sunlight can be provided.

3. Watering: Black-eyed Susan likes moisture, but not too wet, that is, no water accumulation. During the flowering period and when the growth rate is relatively fast, it requires relatively more water and needs to be kept moist. But in winter, you can't water it too much.

4. Fertilization: Black-eyed Susan has high nutrient requirements. In addition to sufficient base fertilizer, you also need to apply fertilizer every two weeks to make it grow more vigorously.

2. Breeding techniques

1. Reproduction: It can be done by sowing. Although Black-eyed Susan can also be propagated by cuttings, the growth of the plant will be relatively poor after this method of propagation. First, choose the right seeds and substrate. When sowing, pay attention to evenness. The next thing is to control the conditions after sowing. In addition to the temperature being between 20 and 30 degrees, additional shade and humidity maintenance are also required.

2. Pruning: Black-eyed Susan grows very vigorously under suitable environment. Therefore, pruning is necessary from time to time. There is no specific frequency for pruning. Just trim any unsuitable branches when you notice them. Furthermore, it is best to prune it after flowering.

3. Problem diagnosis and treatment

1. Diseases: Black-eyed Susan does not have many diseases. However, under very hot and humid conditions, diseases such as "anthracnose" may occur, which mainly harms the leaves and sometimes the flowers. It can be treated with thiophanate-methyl.

2. Pests: "Aphids" and other pests may also appear. You can use tools to wipe them off, or spray pesticides.
