However, in the process of growing moneywort, pests and diseases are unavoidable, so what should you do when moneywort gets pests? In response, the editor has brought you a complete guide to moneywort pest and disease prevention and control. Once you know it, you no longer need to fear pests!

I. What to Do When Moneywort Gets Pests: Everyday Problems

For flower lovers new to moneywort, simply knowing how to grow and care for moneywort is already good enough; they know nothing about more advanced moneywort knowledge, such as moneywort propagation methods or what to do when moneywort gets pests. However, in the process of growing moneywort, encountering pests is very common, so what should you do? Before learning the complete guide to moneywort pest and disease prevention and control, let's first look at the pest problems netizens encounter in daily life.

1. Small White Bugs

Friends new to moneywort, being beginners, are easily cheated, and the moneywort they buy back may have small white bugs under the leaves, as shown in the picture above, so what should be done?

Solution: These are cottony cushion scale insects; spray with 1000x diluted omethoate solution to kill them. If you don't have insecticide on hand, you can also apply garlic juice, which also has a good pest-repellent effect.

2. Bugs Inside Every Leaf

As shown in the picture above, many flower lovers encounter the situation shown above, where there is a bug inside every leaf, which looks quite scary. What should be done in this situation?

Solution: The bugs inside the moneywort leaves are pests. At this point, spraying insecticide is not effective. You should cut off all the leaves and wait for new leaves to regrow.

3. A Bunch of Small Bugs

Some flower lovers also encounter the situation above, where the leaves are full of bugs. One look tells you it's not good, so what should be done?

Solution: These are aphids; buy pesticide and spray it. If the effect is not obvious, just as in the previous case, you can cut off all the leaves and wait for new leaves to regrow.

4. Leaves Clearly Bitten by Bugs

As shown in the picture above, many flower lovers have encountered this situation: no bugs are found, but the moneywort leaves have already been chewed up by bugs. What should be done then?

Solution: It is clearly bug damage. At this point, spraying pesticide won't work. You should cut everything off, apply a little fertilizer water, and it will grow back fine.

II. Moneywort Pest and Disease Prevention and Control Methods

(1) Root Rot

This disease mainly harms seedlings. There are three control methods:

1. Select and breed disease-resistant varieties;

2. Pull out diseased plants and burn them in a centralized manner;

3. Pour 0.3% limewater on the affected area to prevent spread.

(2) Mold Disease

This disease mainly harms the stems during the growth period, appearing as water-soaked spots when affected, which rot after expanding. There are three control methods:

1. Diseased parts should be promptly removed and burned;

2. Improve ventilation conditions;

3. In the early stage of disease, spray with 50% thiophanate-methyl 1000-1500x diluted solution. Once every 15 days, for 3-4 consecutive times.

(3) Armyworms

These insects mainly harm the leaves. There are four control methods:

1. During the period when larvae enter the soil to pupate, dig the soil to destroy the pupae;

2. In the young larval stage, spray with 90% trichlorfon 1000x diluted solution;

3. Taking advantage of the larvae's death-feigning habit, manually capture and kill them in the early morning;

4. At the peak emergence of adults, use sugar-vinegar toxic liquid to trap and kill them.

(4) Caterpillars

These larvae feed exclusively on moneywort leaves. There are three control methods:

1. In winter, turn over the soil around affected plants to kill pupae;

2. During the larval hatching period, spray with 90% trichlorfon 2000x diluted solution to kill larvae, with better results;

3. During the adult stage, use black light lamps to trap and kill adult moths.

Introduction to the Growth Habits and Cultivation Methods of Copper Coin Grass

Copper coin grass, also known as copper coin grass, South American pennywort, coin grass, round coin grass, shield-leaf pennywort, money lotus, etc., is a perennial herbaceous plant of the Apiaceae family. The plant has a trailing nature and very strong spreading ability, making it an excellent ground cover plant. Its shape resembles both copper coins and small lotus leaves. It is one of the most beautiful and easy-to-grow aquatic plants. Let's take a look at the cultivation methods and precautions for copper coin grass!

Growth Habits of Copper Coin Grass

Copper coin grass is native to Europe and is now widely distributed in 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 soil, but soft, well-draining soil is best, or it can be grown directly in water. The optimal water temperature is 22-28°C. It is shade-tolerant, moisture-tolerant, slightly drought-tolerant, highly adaptable, robust by nature, easy to grow, and reproduces quickly. It can grow both in water and on land.

Propagation Methods of Copper Coin Grass

Copper coin grass is mainly propagated by division or cuttings, mostly carried out from March to May each year. It is easy to cultivate; keep the soil moist, and roots will develop in about 1-2 weeks. Seeding can also be used for propagation. For the growing medium, a mixed substrate 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 cultivation in water basins and ponds. If grown in water, be sure to change the water once a week and add special liquid fertilizer for foliage plants.

Cultivation Methods of Copper Coin Grass

1. Soil: Copper coin grass is not strict about soil requirements. It can grow in yellow soil, red soil, or black soil, and even in poor soil. However, its drought resistance is not strong, and it grows best in fine, slightly acidic, moist, low-fertility loam. It is suitable for fertile, loose soil with high water absorption and good water retention, and can also be cultivated in moist riverbanks, swamps, grasslands, or low-hardness freshwater. The growing medium can be a mix of 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 2-3 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 fertilizer effectiveness in water for a relatively long time. Just 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 you should frequently spray water on the plant to maintain high air humidity. The leaves should be kept clean to facilitate photosynthesis. In winter, the pot soil should be kept on the dry side. Follow the principle of preferring wet over dry when watering, and avoid waterlogging, otherwise root rot is likely. Tap water in the north should be sun-exposed and left standing for 1-2 days before use. During the growing period, water once every 2-3 days to keep the pot 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 special liquid fertilizer for foliage plants. If using soil cultivation, you must maintain moisture long-term. Water once every morning, but not too much; water until it flows out of the drainage holes at the bottom, ensuring the pot soil is thoroughly wet.

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

5. Light: Copper coin grass is shade-tolerant, and partial sun or shade is best. Avoid strong direct sunlight; the more shaded the environment, the more likely the leaves will rot. Copper coin grass does not compete for light, but if you let it receive 4-6 hours of scattered light daily, or give it 8-10 hours of artificial light, it will grow even better.

6. Disease Prevention: Copper coin grass has very few pests and diseases. It has strong growth adaptability and requires no deliberate care. After growing for a period, copper coin grass will fill the entire container. Frequently spray water on the leaf surface to clean the leaves and keep them green and glossy. After growth becomes dense, pay attention to ventilation, otherwise the plant is prone to yellowing.

Precautions for Cultivating Copper Coin Grass

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

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

3. Copper coin grass, 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 loves light and water. As long as light and water are sufficient, it will be full of vitality.

4. Copper coin grass does not need a very large pot; you can also use a relatively large bowl to plant it, and a narcissus pot works too. When planting, you can plant it flat, covering the rhizomes so they are not visible. Avoid planting too deep. Then place it in partial shade for a week and wait for new leaves to grow before exposing it to sunlight.

5. Copper coin grass sometimes develops yellowing leaves, mainly caused by the following reasons, which should be avoided as much as possible. First, the pot soil has been too wet or too dry for a long time, without watering as soon as it dries. Second, the roots have already been frost-damaged in winter. Third, in spring it is moved outdoors too eagerly, and the copper coin grass temporarily cannot adapt to the sudden climate change. Fourth, it has been placed in a poorly ventilated environment for a long time. Fifth, the leaf surface has not been sprayed and cleaned for a long time, accumulating dust and hindering photosynthesis.

6. If you find that new leaves are generally turning yellow, you can spray a compound fertilizer mainly composed of nitrogen on the leaf surface. If water moss appears on the roots or in the water, clean and change the water immediately, otherwise it is unfavorable for plant growth and affects ornamental value. Usually pay more attention to whether the water in the container is sufficient to avoid drying up.

Handling Flowering in Copper Coin Grass

Copper coin grass is often grown as a foliage plant, but it also blooms. However, the flowers have a slightly faint foul odor. How to deal with copper coin grass flowering mainly depends on the flower lover's own attitude. Here we mainly provide some simple analysis for reference. If you want to keep the flowers, just let them grow; if not, 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, copper coin grass can produce seeds, but compared to division, the seed germination rate is low and the growth cycle is long.

The Cultivation Benefits of Copper Coin Grass

1. Ornamental value: Copper coin grass has distinct nodes, one segment after another, with each node bearing a leaf, 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: Copper coin grass has round, shield-shaped leaves like a copper coin, with long petioles and wavy margins. It blooms small yellow-green flowers in summer and autumn. Copper coin grass is simple to cultivate and manage, with a beautiful plant shape and verdant leaf color. It is very pleasing to look at and is currently one of the most popular aquatic plants among flower lovers, widely praised. This plant can be potted outdoors in warm regions and is suitable for water trays, aquariums, ponds, wetlands, and indoor water landscaping. When cultivated in aquariums, it is often used as a foreground plant.

3. Feng shui symbolism: Copper coin grass can be used for indoor water landscaping, can purify water quality, and its green leaves can purify indoor air, so it is beneficial to the indoor environment. Furthermore, in Chinese culture, which emphasizes symbolism and homophones, copper coin grass has round leaves like mini lotus leaves, quite cute, resembling ancient copper coins, symbolizing reunion and continuous good fortune. Moreover, its name includes the characters "copper" and "coin," giving it a naturally different symbolic meaning. Having copper coins at home means rolling in wealth, so it is considered a symbol of wealth.

4. Medicinal uses: Copper coin grass 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.

Hydroponic Cultivation of Copper Coin Grass

1. Water quality: Copper coin grass actually has no special requirements for water quality; ordinary water is sufficient, but 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, it is enough to replace roughly half the container. In winter, it is more special: change only one-third of the water.

2. Water and fertilizer: Copper coin grass synthesizes its own nutrients. If growing hydroponically, it is recommended to fertilize less, though 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 copper coin grass is grown hydroponically, its sunlight requirements are still relatively important. Generally, at least half a day of sunlight is needed. If growing in a greenhouse, it is recommended to use fluorescent lamps to ensure 5 hours of light per day.

4. Pests: Generally, bugs 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.

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

Growing Copper Coin Grass from Seeds

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

2. Seeds need access to air. If clay pellets and stones are placed too early during hydroponic cultivation, the seeds will more or less fall under the stones and be very difficult to germinate. Therefore, it is generally recommended to first find a bottle cap (a beverage 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, when you open the seed package, you will find that the seeds are wrapped in a green powder coating. Do not blindly crush it; that is really not the seed shell. Pour the seeds into the bottle cap, but do not pour them all at once, to prevent failure and leave a backup for next time. Pour in a small amount of water, just enough to dissolve the green coating, then cover with plastic wrap.

4. Place the prepared bottle cap in a dark place and wait 2-4 days, and you will see that some seeds have already broken their shells, and some even show white roots. Every night, remove the plastic wrap to let the seeds breathe, to prevent root rot.

5. When the white roots are 4-6 mm long, you can expose them to sunlight, but it is best to do so at 8-9 o'clock to avoid sunburn. If not exposed to sunlight, the leaves are not easy to grow out.

6. When the seeds sprout to the point of about to shed their shells, they can be potted. Place clay pellets or stones into a cup, put the small sprout in, gently fix the roots with clay pellets or stones, add water, and it is best to pour water along the edge of the cup, otherwise the fixed seedling will be washed away. Pour water until it just touches the roots.

7. Expose them to sunlight every day, avoid strong winds, add water timely, and if necessary add some hydroponic nutrient solution, and the seedlings will grow vigorously.
