Pennisetum is easy to raise, it does not require high soil, even if the soil is slightly poor can grow. However, it is a kind of drought resistant plant. Based on this, it requires that the selected soil is loose, breathable and well drained. Cultivation of the soil is the key. Appropriate soil is conducive to the growth of the plant and will not cause the plant to rot and die.
It can accept half sunshine and is more shade resistant, but it should not be exposed to direct sunlight. Therefore, it can be maintained in half shade environment, but not too shade. The lack of light will make the leaves rotten, so it is necessary to guarantee 4-6 hours of light every day, which is conducive to the growth of the plant.
It requires a warm growing environment, which generally grows well between 10-25 ℃, the temperature in summer is not more than 32 ℃, and the temperature in winter is not less than 5 ℃.
It has a high requirement for water. It likes humid environment. In summer, when the temperature is high, there are more leaves and water is very easy to lose, so we need more water in summer. Often spray water to plants, can improve the air humidity, play a role in cooling, but also can make the leaves clean and tidy, convenient for photosynthesis. In winter, the temperature is low. The basin soil is required to be dry, rather dry than wet. There should be no water in the basin. The water will make the roots of the plant breathe badly and rot.
When the copperhead grass is watering, it is usually watered once every half a month during its growth period to keep the basin soil moist. If it is water fed, it is necessary to change water every 7-10 days in spring and summer, and every half month in autumn and winter. Under normal circumstances, northern tap water needs to be left in the sun or shade for 1-2 days before use.
There is also a large demand for fertilizer. In the vigorous growth period, topdressing can be done every 2-3 weeks. The amount of fertilizer can be determined according to the size of growing utensils. If the container is small, the amount of fertilizer can be reduced appropriately to avoid fertilizer damage.
1. Flowerpot selection. When choosing a flowerpot, it should be determined by the plant size. Generally speaking, it doesn't need a large basin, so you can use a larger bowl or a narcissus basin for maintenance. When planting, it's OK to cover the rhizome. Don't bury it too deep. After planting, it is placed in a half shade place, and can be exposed to sunlight for a period of time.
2. Trim. It is rarely necessary to prune. However, if the leaves are too dense or yellow, you need to prune them to remove the yellow leaves and redundant leaves. In the spring, we can change the potting, when changing the potting, we can prune the roots and propagate in different plants. It is, still can be in when changing basin to undertake plastic surgery to copperhead grass. If the plant is too high and grows in vain, we should cut off the high fat of the plant so as to make it have more new branches.
