How to grow black grass

1. Maintenance methods

1. Temperature: Black seed grass prefers a cool growing environment, so it is generally planted in the north. If the temperature is too high, the growth will be slow. Of course, the temperature cannot be too low, so under normal circumstances, it only needs to be kept warm. If it is too hot in summer, it can be cooled down.

2. Watering: It likes a humid growing environment, so provide enough water during the growth period. Water it about every three to five days in spring. In summer, water loss will be faster, so it needs to be watered every day. More watering in summer can also reduce the temperature. Water once a week in winter.

3. Light: It likes warm and sufficient light. In spring and autumn, it can receive full sunlight and grow vigorously. In summer, it can be properly shaded because its flowers are relatively fragile. If exposed to strong light, they will wither and die, and the overall growth of the plant will slow down.

4. Fertilization: Fertilizer is relatively important for black grass. Before it blooms, it needs to be applied with nitrogen fertilizer once a month. Nitrogen fertilizer can promote its growth and development. However, during the flowering period, nitrogen fertilizer should be stopped and fertilizer water cake should be used instead, applied once a month. After the flowering is over, continue to fertilize it once, and stop fertilizing in winter to ensure that normal activities are not affected.

2. Breeding techniques

1. Reproduction: Sowing is its main method, mainly in spring. The temperature for seed germination is between 15 and 20 degrees, and black seed grass is not resistant to transplantation, so the environment and location must be selected before planting.

2. Pruning: There is no need to prune too heavily. Like caring for other plants, you only need to cut off some withered and yellowed branches and leaves. You can also cut off the withered flowers to reduce the loss of nutrients.

3. Problem diagnosis and treatment

1. Disease: Leaf spot disease will occur, which will cause the branches and leaves of the plant to be unsightly, turning yellow or withering, and can dilute pesticides.

2. Pests: Aphids will appear and affect the ornamental value. You can directly cut off the relevant branches and leaves.
