How to Grow Copper Coin Grass Hydroponically? A Detailed Guide to the Latest Methods
Copper Coin Grass, also known as South American pennywort, coin grass, round coin grass, shield-leaf pennywort, golden coin lotus and so on, likes moist environmental conditions and is suited to growing in water trays, aquariums, ponds or wetlands. It is not strict about its environment, does best in a moist setting, and is suitable for aquatic growth. It grows toward the light, easily develops a lopsided crown, and becomes leggy. Now let us take a look at how to grow Copper Coin Grass hydroponically!
Can Copper Coin Grass Be Grown Hydroponically?
Copper Coin Grass can be grown hydroponically. Copper Coin Grass likes warmth and moisture, and is best cultivated in half-day sun or shade. It dislikes direct sunlight. It is not fussy about the growing medium, though a loose, well-draining potting soil is best, or it can be grown directly in water. The optimal water temperature is 22-28°C. It is shade-tolerant and moisture-tolerant, slightly drought-tolerant, highly adaptable, robust by nature, easy to plant, and fast to propagate. It can grow both in water and on land. Copper Coin Grass is afraid of the cold. In winter, for Copper Coin Grass kept outdoors, you can pour out all the water and place it in a south-facing, sunny, sheltered spot, and it can overwinter safely, though some leaves will die back, and the underground roots will sprout again the following spring. In cold northern regions without heating, you can make a cover and enclose the pot with it, pour out the water, and keep it moist; as long as the room temperature does not drop below freezing, it will likewise continue to grow the following year.
Hydroponic Growing Methods for Copper Coin Grass
1. Water quality: Copper Coin Grass has low requirements for hydroponic water quality. As long as the water does not smell bad or breed insects, ordinary tap water can be used directly for hydroponics. In summer, change the water about once every 3-4 days, replacing half the water in the container each time; in winter, change it once a week, replacing one third each time.
3. Temperature: Copper Coin Grass is suited to production in most of the hot, humid regions of the south, especially in summer, when it propagates particularly quickly. Its normal growing temperature is most suitable between 10-26°C; too hot or too cold will both inhibit the growth of Copper Coin Grass.
3. Light: Copper Coin Grass loves sunlight intensely while growing, so it is best to place the water container outdoors or by a window with ample light. If grown indoors, the daily sunlight exposure should be no less than 4-5 hours. In addition, UV lamps or strong fluorescent lamps can be used instead of sunlight for lighting.
4. Fertilizing: Copper Coin Grass can produce the nutrients it needs for growth on its own through photosynthesis, so it can be fertilized relatively little. If fertilization is needed, ordinary fertilizer can be dissolved in the water container and left for it to absorb on its own, but be careful that the amount is not too concentrated; a small amount is enough.
5. Pests: Copper Coin Grass generally does not attract pests, but soft-bodied animals such as aquatic snails may nibble the roots and tender shoots. If such small creatures are found in the water, they should be removed by hand to prevent them from multiplying in large numbers.
Precautions for Hydroponic Copper Coin Grass
1. There is no need to change the water especially frequently; provided the water volume in the container is sufficient, once a week is enough. In summer, you can change the water a bit more frequently, mainly to stop mosquitoes from laying eggs in it.
2. Maintain enough light. Only when it receives more than 4 hours of sunlight a day can Copper Coin Grass grow luxuriant and emerald green. Copper Coin Grass especially loves the sun; under ample sunlight it can grow rapidly even without fertilizer. Conversely, if the light is insufficient or it is kept in a dark room for a long time, the leaves of Copper Coin Grass easily turn yellow and wither.
3. As for fertilizing, there is no need for too much fuss. If you keep goldfish at home, you can pour the water from changing the goldfish tank into the Copper Coin Grass container, which can make Copper Coin Grass grow better.
4. In the south, it grows well and can survive naturally within a temperature range of 16-24°C. However, too high or too low a temperature will both inhibit the growth of Copper Coin Grass, and at high temperatures small insects are also more likely to appear in the water.
5. When growing Copper Coin Grass in water, yellowed leaves will rot in the water and spoil the water quality, so we should check the water container regularly and remove any moldy, rotting leaves as soon as we find them.
6. Vigorously growing Copper Coin Grass can spread to fill the container within a month, so we should appropriately prune and divide it, transplanting overly dense Copper Coin Grass into other water containers, so that mature leaves do not block the light for tender leaves and affect normal plant metabolism.
