How to raise Tongqian grass best

Copper money grass is also known as South American coriander, coin grass, round coin grass, shield leaf day coriander, gold lotus, etc., with round shield-shaped leaves, such as a copper coin, with a long handle, wavy margin, small yellow-green flowers in summer and autumn, simple culture management, beautiful plant shape, green leaves, very good-looking, is currently one of the flower friends' favorite aquatic plants, let's take a look at how to raise the best!

The growth habit of Rabdosia angustifolia

Tongqian grass likes to be warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, regardless of cultivation soil, it is better to cultivate soil with good soft drainage, or directly cultivated with water, the optimum water temperature is 22-28 degrees. Shade-tolerant, moisture-tolerant, slightly drought-tolerant, strong adaptability, strong nature, easy to plant, rapid reproduction, amphibious. Tongqian grass is afraid of the cold. Tongqian grass put outdoors in winter can pour out all the water and put it in a place facing south to the sun and leeward. It can survive the winter safely, but the leaves will die partially, and the underground roots will sprout again next spring. If there is no heating in the cold areas of the north, you can make a cover with a basin cover, pour out the water and keep it moist. As long as the room temperature is not lower than below zero, it will also continue to grow in the coming year.

Propagation methods of Rabdosia angustifolia

Rabdosia angustifolia is mainly propagated by split-plant method or cutting method, which is mostly carried out from March to May every year. It is easy to cultivate and keep the cultivated soil moist. It can take root in about 1-2 weeks, and sowing method can also be used to raise seedlings. The mixed matrix composed of rotten leaves, river mud and garden soil can be used to cultivate soil, and the proportion of them is 0.5 by volume. The potted plant can be operated after the seedling is formed, and the medium-sized flowerpot without drainage hole is often used as the planting container. in order to obtain a better ornamental effect, one seedling can be put in each pot and irrigated after the end of the operation. the planting operation is best carried out on a cloudy day.

How to raise Tongqian grass best

1. Soil culture of Rabdosia angustifolia: potted Rabdosia angustifolia can be operated after the seedlings are formed, and medium-sized flowerpots without drainage holes are often used as planting containers. In order to obtain better ornamental effect, one seedling can be put in each pot and irrigated at the end of the operation. In order to slow down the seedlings, the colonization operation is best carried out on a cloudy day.

2. Hydroponic culture of Rabdosia angustifolia: the requirement of water quality is not strict, it can be cultivated in fresh water with low hardness, and the salinity should not be too high. The pH of the water body should be controlled between 6.5 and 7.0, that is, from slightly acidic to neutral. It has a large demand for fertilizer, and it can be topdressing every 2-3 weeks in the vigorous growth stage. If planted in pots or containers, a small amount of fertilizer is required, such as quick-acting fertilizer-Huabao No.2, or slow-acting fertilizer-magic fertilizer (which can maintain fertilizer effect in water for a long time).

3. Half-water and half-soil culture method: it is best not to use only water to cultivate coppergrass. The general effect of pure water culture is not very good, and the effect of half-water and half-soil will be better, just like raising sleeping lotus, which is easy to raise. If only water is used, hydroponic nutrient solution should be added and the bottom should be pressed with river sand, ceramsite or pebbles. Codonopsis lanceolata is extremely fond of sunlight when it grows, so it is best to put the basin outside or by the window where there is plenty of light. If cultivated indoors, the daily sun exposure time should not be less than 4: 5 hours.

Matters needing attention in the culture of Rabdosia angustifolia

1. Tongqian grass likes warm and high temperature, 80% sunshine is suitable, insufficient light or excessive shading will lead to excessive growth of stems, yellowing and decay of leaves, need to use a medium with good water retention, and often keep moist. Amphibious copper grass is often found in aquatic ponds, wetlands and other spaces, and aquariums and aquariums are also suitable.

2. Rabdosia angustifolia generally does not need a lot of pruning, and when the leaves are too dense, the withered bottom leaves and outer old leaves and diseased leaves should be removed in time to improve lighting and ventilation conditions. In spring, when the basin is full of roots, change the basin and reshape the ramet. If the growth of the plant is too high, it should be pruned and pressed to promote the germination of new branches at the base of the stem and leaf.

3. Tongqian grass likes sunlight and water, and can be cultivated in water, soil, and half-water and half-soil. The leaves are round, very lovely, and very easy to raise. In short, you can do whatever you want. It does not compete for fat, but it likes light and water. As long as there is enough light and water, it is full of life.

4. Copper grass does not need a large basin, it can also be planted in a relatively large bowl, and daffodils can also be planted. When planting can be flat planting, to cover the rhizome so that it is better not to see, do not be too deep. Then leave it in the semi-shade for a week and wait for the new leaves to grow and see the sun again.

5. The yellowing of leaves sometimes occurs in Rabdosia angustifolia, which is mainly caused by the following reasons, which should be avoided as far as possible. First, the basin soil has been too wet or too dry for a long time and has not been watered as soon as it is dry. Second, the root system has been frostbitten in winter. Third, the spring is eager to go out of the room, copper grass temporarily unable to adapt to the abrupt climate. Fourth, it is placed in the environment of poor ventilation for a long time. Fifth, the leaf surface is not cleaned with water for a long time, which accumulates dust and hinders photosynthesis.

6. If it is found that the new leaves are generally yellowing, compound fertilizer based on nitrogen fertilizer can be sprayed on the leaves. Wash and change water immediately when water moss appears in the root system or water, otherwise it is disadvantageous to the growth of the plant and affects the ornamental. Usually, we should pay more attention to whether the water in the container is sufficient or not, so as to avoid exhaustion.
