What to Do When Copper Coin Grass Leaves Turn Yellow and Black? A Detailed Guide to Growing It

The name "copper coin grass" sounds very auspicious, and in fact it truly is. In feng shui, it is a treasure plant that attracts wealth, and many people love it very much. Growing a pot of it at home is not only attractive but also helps promote good feng shui. So how exactly should copper coin grass be grown? Let's find out below.

What to do when copper coin grass leaves turn yellow and black

1. If grown fully hydroponically, it tends to lack nutrients and does not grow as well as in soil. If grown fully in soil, it often does not get enough water, so water it every day until water comes out of the bottom of the pot. Semi-hydro culture with half water and half soil is best.

2. It needs plenty of sun; even a little shade will keep it from growing well.

3. The rhizomes grow extremely fast, constantly coiling and piling up in the pot. Over time they absorb too many nutrients, and the leaves end up lacking nutrients instead. So every so often, such as every two to three months, clean the roots and repot. Throw away the excess roots and keep just a small section. Copper coin grass is a low-maintenance plant that is very easy to keep alive. A small piece of stem with a bit of root can grow into a large pot.

4. Applying some fertilizer every month will help it grow better.

How to grow copper coin grass

1. Soil: Copper coin grass is not strict about soil. It can grow in yellow loam, red loam, or black loam, and even in poor soil. However, it is not very drought tolerant and grows best in fine, slightly acidic, moist, low-fertility loam. It is suitable for fertile, loose soil that absorbs and retains water well, and it can also be grown on moist riverbanks, in marshes, in grassland, or in low-hardness freshwater. The growing medium can be mixed from leaf mold, river mud, and garden soil in a ratio of 5:2:2.

2. Fertilizing: Copper coin grass has a relatively high demand for fertilizer. During the vigorous growth stage, apply fertilizer once every 2 to 3 weeks. If grown in a pot or container, only a small amount of fertilizer is needed, such as the quick-acting fertilizer Huabao No. 2, which can maintain its fertilizing effect in water for a relatively long time and ensure the water quality is slightly acidic or neutral.

3. Watering: Copper coin grass prefers a relatively moist growing environment. Because it has many leaves and high transpiration, in summer spray the plant often to maintain higher air humidity, and keep the leaves clean to help photosynthesis. In winter, the potting soil is better kept on the dry side. Follow the principle of preferring moist over dry when watering, and avoid waterlogging, otherwise the roots can easily rot.

Tap water in the north should be left in the sun to stand for 1 to 2 days before use. During the growing season, water once every 2 to 3 days to keep the potting soil moist. For water culture, change the water once every 7 to 10 days in spring and summer, and once every half month in autumn and winter. If growing in water, be sure to change the water once a week and add a special nutrient solution for foliage plants. If using soil culture, be sure to keep it moist long term. Water once every morning, but do not overwater; water until it flows from the bottom holes, just enough to make sure the potting soil is thoroughly moistened.

4. Temperature: Copper coin grass likes warm, humid environments but is not cold tolerant. It grows well at temperatures of 10 to 25°C. When the summer temperature rises above 32°C, growth stops, and in winter the temperature must not drop below 5°C.

Notes on growing copper coin grass

1. Choosing a pot: When choosing a pot for copper coin grass, decide based on the size of the plant. Generally speaking, copper coin grass does not need a very large pot; you can use a slightly larger bowl or a narcissus pot to grow it.

2. Pruning: Copper coin grass rarely needs pruning, but if the leaves are too dense or if leaves turn yellow, prune it by removing the yellow leaves and excess leaves.

How copper coin grass gets through winter

In the south and in northern homes with heating, the temperature is relatively high, so copper coin grass can grow normally. However, note that copper coin grass should not be placed directly on floors with underfloor heating or exposed to air-conditioner airflow. Copper coin grass is a sun-loving plant, so when grown indoors it should also be placed somewhere with sunlight, or moved outdoors to bask in the sun on a clear morning.

So it turns out that copper coin grass is also fairly easy to grow. As long as the water, fertilizer, and temperature are suitable, it will certainly grow well. But in winter, it must receive special care. The cold winter is a great test for this cold-sensitive plant, and if cared for improperly even slightly, it can freeze to death.
