1. Temperature: blackgrass likes a cool growth environment, so it is generally planted in the north. If the temperature is too high, the growth will be slow. Of course, the temperature should not be too low, so it is only necessary to keep warm under normal circumstances. If it is too hot in summer, it can be cooled.
2. Watering: I like the humid growing environment, so I need to provide enough water during the growing period. In spring, I need to water once every three to five days. In summer, the water loss will be faster. I need to water every day. In summer, more water can cool down. Once a week in winter.
3. Light: like warm and sufficient light, like spring and autumn can normally receive full day light, growth will also be very strong, in summer can be appropriate shade, because its flowers are relatively fragile, if the strong light will wither and wither, the overall growth of the plant will be slow.
4. Fertilizer application: fertilizer is still very important for black grass. Before it blooms, nitrogen fertilizer should be applied once a month. Nitrogen fertilizer can promote its growth and development. However, during the flowering period, it is necessary to stop applying nitrogen fertilizer and use fertilizer water cake once a month. Wait until the end of flowering, continue to give it a fertilizer, in winter to stop fertilization, to ensure that normal activities are not affected.
1. Reproduction: sowing is its main method, mainly in spring. The temperature of seed germination is between 15 ℃ and 20 ℃, and the black grass is not resistant to transplantation, so you should choose a good environment and location before planting.
2. Pruning: do not need to prune too much. Just like other plants, just cut off some withered and yellow branches and leaves. At the same time, you can also cut off the withered flowers to reduce the loss of nutrients.
1. Disease: leaf spot disease will occur, which will lead to unsightness of plant branches and leaves, thus turning yellow or withering, and can dilute pesticides.
2. Insect damage: aphids will appear, which will affect the ornamental, and can directly cut off the relevant branches and leaves.
1. Toxicity: it is not toxic and suitable for breeding.
2. Whether it can be raised at home: Yes, it can beautify the home.
