How to Grow Pennywort? Detailed Guide to Its Growth Habits and Cultivation Methods

Pennywort, also known as South American pennywort, coin grass, round coin grass, shield-leaf pennywort, golden lotus and so on, is a perennial herbaceous plant of the Apiaceae family. The plant has a trailing habit and spreads very vigorously, making it an excellent ground cover plant. Its shape resembles both a copper coin and a series of small lotus leaves, and it is one of the most beautiful and easy-to-grow aquatic plants. Let us take a look below at the cultivation methods and precautions for pennywort!

Growth Habits of Pennywort

Pennywort is native to Europe and is now widely distributed across tropical and subtropical regions of the world. In China it is mainly distributed in the provinces south of the Yangtze River. It likes warm and humid conditions, and is best cultivated in partial sun or shade, avoiding direct sunlight. It is not particular about the growing medium; a loose, well-draining growing medium is best, or it can be grown directly in water. The optimum water temperature is 22-28°C. It is shade-tolerant, moisture-tolerant, slightly drought-tolerant, highly adaptable, robust by nature, easy to grow and quick to propagate, and it can grow both in water and on land.

Propagation Methods for Pennywort

Pennywort is mainly propagated by division or cuttings, mostly carried out from March to May each year. It is easy to grow; keep the growing medium moist and roots will form in about 1-2 weeks. Seed sowing can also be used for raising seedlings. For the growing medium, a mixed substrate made of leaf mold, river mud and garden soil can be used, with a volume ratio of 0.5:2:2. It is moisture-tolerant and an emergent-type plant, so it is also suitable for growing in water basins and ponds. If grown in water, be sure to change the water once a week and add a special nutrient solution for foliage plants.

Cultivation Methods for Pennywort

1. Soil: Pennywort is not strict about soil requirements. It can grow in yellow loam, red loam or black loam, and even in poor soil. However, its drought resistance is not strong, and it grows best in fine, slightly acidic, moist loam with low fertility. It is suitable for fertile, loose soil that absorbs plenty of water and retains it well, and can also be cultivated on moist riverbanks, in marshes, in grassland, or in low-hardness freshwater. The growing medium can be prepared by mixing leaf mold, river mud and garden soil in a ratio of 5:2:2.

2. Fertilizing: Pennywort has a relatively high demand for fertilizer. During the vigorous growth stage, apply fertilizer once every 2-3 weeks. If grown in pots or containers, only a small amount of fertilizer is needed, such as the quick-acting fertilizer Hyponex No. 2, which can maintain its fertilizing effect in water for a relatively long time. Just ensure the water is slightly acidic or neutral.

3. Watering: Pennywort prefers a relatively moist growing environment. Because it has many leaves and a high transpiration rate, in summer it should be sprayed with water frequently to maintain high air humidity, and the leaves should be kept clean to facilitate photosynthesis. In winter, the potting soil should be kept on the dry side. Water according to the principle of preferring moist over dry, and avoid waterlogging, otherwise the roots rot easily. Tap water in the north should be left to sit in the sun for 1-2 days before use. During the growing season, water once every 2-3 days to keep the potting soil moist. For water cultivation, change the water once every 7-10 days in spring and summer, and once every half month in autumn and winter. If grown in water, be sure to change the water once a week and add a special nutrient solution for foliage plants. If grown in soil, be sure to retain moisture over the long term. Water once every morning, but do not use too much water; a good guide is water flowing out of the drainage holes, ensuring the potting soil is thoroughly moistened.

4. Temperature: Pennywort likes a warm and humid environment but is not cold-tolerant. It grows well at temperatures of 10-25°C. When the summer temperature rises above 32°C, growth stops, and in winter the temperature must not fall below 5°C.

5. Light: Pennywort is shade-tolerant, and partial sun or shade is best. Avoid strong direct sunlight; the more shaded the environment, the more likely the leaves are to rot. Pennywort does not compete for light, but if it receives 4-6 hours of scattered light each day, or 8-10 hours of artificial light, it will grow even better.

6. Disease prevention: Pennywort has very few pests and diseases. It is highly adaptable and requires no deliberate care. After being grown for some time, pennywort will fill the entire container. Spray water on the leaves frequently to wash them and keep them fresh and glossy. Once growth becomes dense, pay attention to ventilation, otherwise the plant easily turns yellow.

Precautions for Growing Pennywort

1. Pennywort likes warmth and high temperatures, and 80% sunlight is suitable. Insufficient light or excessive shading will cause the stems to become leggy and the leaves to turn yellow and rot. Use a medium with good water retention and keep it moist at all times. The amphibious pennywort is commonly found in aquatic ponds, wetlands and similar spaces, and is also very suitable for water basins and aquariums.

2. Pennywort generally does not need extensive pruning. When the leaves become too dense, promptly remove withered lower leaves and the outer old and diseased leaves to improve light and ventilation. In spring, when the pot is full of roots, repot and divide and reshape the plant. If the plant grows too tall, prune it back to encourage new shoots to sprout from the base of the stems and leaves.

3. Pennywort, which loves sunlight and water, can be grown hydroponically, in soil, or in a half-water half-soil setup. Its leaves are round and very cute, and it is very easy to grow. In short, you can do whatever you like with it. It does not compete for fertilizer, but it loves light and water. As long as light and water are sufficient, it will be full of vitality.

4. Pennywort does not need a very large pot; a relatively large bowl can also be used for planting, and a narcissus pot works too. When planting, it can be planted flat, covering the rhizomes so they are not visible; be sure not to plant too deep. Then place it in a semi-shaded spot for a week and wait for new leaves to grow before exposing it to sunlight.

5. Pennywort sometimes develops yellow leaves, mainly caused by the following reasons, which should be avoided as much as possible. First, the potting soil is too wet or too dry for a long time, failing to water as soon as it dries. Second, the roots have already been frost-damaged in winter. Third, moving it outdoors too eagerly in spring, so pennywort cannot immediately adapt to the sudden climate change. Fourth, keeping it in a poorly ventilated environment for a long time. Fifth, not spraying and washing the leaves for a long time, so dust accumulates and hinders photosynthesis.

6. If you find that the new leaves are generally turning yellow, you can spray a compound fertilizer based mainly on nitrogen onto the leaves. If water moss appears on the roots or in the water, clean it and change the water immediately, otherwise it is bad for the plant's growth and affects its ornamental value. Usually pay more attention to whether there is enough water in the container to avoid it drying up.

Handling Pennywort Flowering

Pennywort is often grown as a foliage plant, but it also flowers. However, the flowers have a somewhat faint foul odor. How to deal with pennywort flowering mainly depends on the grower's own attitude. Here we mainly provide a simple analysis for growers' reference: if you want to keep the flowers, just let them grow; if you do not want flowers, simply cut them off when they appear. Flowering consumes nutrients. When there are more and more flowers, nutrients are consumed and the leaves begin to turn yellow. It is mainly appreciated as a foliage plant, and the flowers are not attractive and smell a bit foul. Of course, pennywort can produce seeds, but compared with division, seeds have a low germination rate and a long growth cycle.

The Cultivation Value of Pennywort

1. Ornamental value: Pennywort has distinct nodes, one after another, with a leaf growing at each node, and it can keep extending. Its underground creeping stems grow at an astonishing rate, spreading wherever they reach. It is one of the most beautiful and easy-to-grow aquatic plants.

2. Landscaping value: Pennywort has round, shield-shaped leaves like a copper coin, with long petioles and wavy margins, and it produces small yellow-green flowers in summer and autumn. Pennywort is simple to cultivate and manage, with a beautiful plant shape and verdant leaf color; it is very pleasing to look at. It is currently one of the most popular aquatic plants among growers and is widely praised. In warm regions this plant can be grown outdoors in pots, and it is suitable for water basins, aquariums, ponds, wetlands and indoor water landscaping. When grown in an aquarium, it is often used as a foreground plant.

3. Feng shui symbolism: Pennywort can be used for indoor water landscaping; it can purify water quality, and its green leaves can purify indoor air, so it is beneficial to the indoor environment. Furthermore, in Chinese culture, emphasis is placed on symbolic meanings and homophones. Pennywort has round leaves, like mini lotus leaves, quite cute, and like ancient copper coins. It symbolizes reunion and continuous good fortune, and its name contains the two characters "tong" (copper) and "qian" (coin), which naturally gives it a different meaning: a home with copper coins means rolling wealth, so it is regarded as a symbol of wealth.

4. Medicinal uses: Pennywort can also be used as a Chinese medicinal herb to dispel wind, strengthen the intestines, improve eyesight and clear summer heat, clear heat and remove dampness, detoxify and promote urination, and so on.

Growing Pennywort in Water

1. Water quality: Pennywort actually has no particular requirements for water quality; ordinary water can satisfy it, and river water is best because it is relatively rich in organic matter. Generally, the water only needs to be changed about once a week, and when changing the water, it is enough to replace roughly half the basin. In winter it is a bit different: changing one third of the water is enough.

2. Water and fertilizer: As for the nutrients pennywort synthesizes on its own, if growing it hydroponically it is recommended to fertilize sparingly. However, in the early growth stage you can use hydroponic fertilizer and add some hydroponic nutrient solution, but be careful not to make it too concentrated.

3. Light: If pennywort is grown hydroponically, its sunlight requirements are still relatively high. Generally it needs at least half a day of light. If grown in a greenhouse, it is recommended to use fluorescent lamps to ensure 5 hours of light per day.

4. Pests: Generally, insects will not grow on the leaves. However, because it is grown in water, there is no guarantee that some aquatic pests will not appear in the water, so it is recommended to remove them promptly when they do.

5. Temperature: Because of the environment pennywort originally grows in, the most suitable temperature is 20°C. Because it is hydroponic, generally there will be no problem as long as the temperature does not fall below 10°C. But it cannot be too high or too low, because that will inhibit its growth.

Growing Pennywort from Seed

1. Obtaining seeds: You can buy them from relatively reputable online stores or flower markets, or receive them as shares from other growers.

2. The seeds need to be exposed to air. If you put in expanded clay pebbles and stones too early during the hydroponic process, the seeds will more or less fall beneath the stones and then it becomes very difficult for them to germinate. Therefore, it is generally recommended to first find a bottle cap (a drink bottle cap will do), then prepare some sun-exposed tap water, plastic wrap and a small rubber band, and everything is ready.

3. If purchased from an online store or flower market, remove the seed packaging and you will find that the seeds are all wrapped in a green powder. Do not blindly crush it; that really is not the seed shell. Pour the seeds into the bottle cap, but do not pour them all out at once, to prevent failure and keep a backup for next time. Add a small amount of water, just enough to dissolve the green coating, then cover with plastic wrap.

4. Put the prepared bottle cap in a dark place and wait 2-4 days, and you will see that some seeds have already broken through their shells; on some you can even see white roots. Every evening remove the plastic wrap to let the seeds breathe, which prevents root rot.

5. Once the white roots are 4-6 mm long, they can be exposed to the sun, but it is best to do so at 8-9 o'clock to avoid sunburn. If they are not exposed to the sun, the leaves are not easy to grow out.

6. When the seeds have germinated to the point of being about to shed their shells, they can be potted. Put expanded clay pebbles or small stones into a cup, place the small sprouts in, gently fix the roots with the expanded clay pebbles or small stones, and add water. It is best to pour the water along the edge of the cup, otherwise the fixed seedlings will be washed away. Pour in water until it just touches the roots.

7. Expose them to sunlight every day, do not let them be hit by strong wind, add water as needed, and if necessary add a little hydroponic nutrient solution, and the seedlings will grow strong and healthy.

How to Grow Pennywort: Cultivation Methods and Tips for Pennywort

Pennywort is a beautiful foliage plant, named because its leaves mostly resemble ancient copper coins. It can not only beautify the environment but also has a certain feng shui function. So how should this pennywort be grown? In a moment I will write out the cultivation methods and tips for pennywort, and after reading them everyone will know how it should be grown.

1. Pennywort can be grown hydroponically

Pennywort can normally be grown hydroponically. When growing pennywort in water, the salinity of the water must not be too high; its pH value is best kept at around 7.0, that is, the water should be slightly acidic or neutral. When growing pennywort hydroponically, its demand for fertilizer is relatively high, and during its peak growing season it should be fertilized once every two weeks.

2. Pennywort can be grown in soil

Pennywort has strong vitality and does not have high soil requirements; any loose, well-draining growing medium will do. When growing pennywort in soil, its fertilizer requirements are also not high. A sufficient base fertilizer can be used at the bottom of the pot, and during normal cultivation it is enough to fertilize once every twenty days. After winter arrives, stop supplying fertilizer.

3. The living habits of pennywort

Whether pennywort is grown hydroponically or in soil, its living habits do not change. It likes a semi-shaded environment and should not normally be placed in direct sunlight. When the high-temperature weather of summer arrives, carry out the necessary shading treatment, and spray water on the leaves two or three times a day to increase air humidity, otherwise the leaves of pennywort will turn yellow and fall off.

Cultivation Methods for Pennywort, and What Precautions There Are

Pennywort, also known as marsh pennywort, is a perennial wetland herbaceous crop. Pennywort has round leaves and very vigorous vitality, and whether grown in soil or hydroponically its survival rate is very high. Moreover, pennywort's underground rhizomes grow rapidly, and each node can produce new roots and leaves. In summer and autumn it can also produce small yellow-green flowers. The rhizomes, stems and leaves of pennywort can all be eaten as vegetables, and it has the effects of clearing heat and removing dampness, promoting urination and detoxifying. Below we introduce the cultivation methods and precautions for pennywort.

Hydroponic propagation: Take a section of root with more than 2 nodes and soak it in clean water for 2 days. Small rootlets will grow from the nodes of the pennywort, and sometimes small leaves will also grow. Put a small amount of growing medium into a shallow basin, gently place the pennywort roots on the surface of the soil, cover with a thin layer of soil, then add some small gravel to keep the water clear. Water until the small gravel is submerged. After about 4 days, small plants will grow. Be careful to replenish water frequently, with the aim of keeping the gravel moist.
