How to do with the dry edge of the leaves? learn four tricks to make the leaves more green.

The leaf edge of Rabdosia angustifolia is usually emerald green, and there will be irregular sawtooth, which has been introduced in detail in the difference between Artemisia angustifolia and Codonopsis lanceolata, but some flower friends have encountered the phenomenon of drying up the edge of the leaves raised by themselves. it not only affects the beauty, but also makes people have a headache. What should I do if I encounter this situation? The editor will tell you the solution.

What is the reason for the dry edge of the leaves of Rabdosia angustifolia

1. Improper watering

Improper watering includes two aspects, namely, not watering thoroughly each time, or watering too much, both of which will lead to leaf drying, because not watering thoroughly will make the lower roots have no water to absorb, and too much watering will lead to root rot, which is disadvantageous to the growth of Rabdosia angustifolia.

Solution: when watering, you should see water seeping from the drainage hole at the bottom of the flowerpot, otherwise it means that the water has not been watered through, and stop watering immediately after watering, and do not continue watering to cause stagnant water in the soil.

2. Climate change

In late autumn, the climate change is more obvious, especially the temperature may drop sharply. If the grass is not moved back indoors in time according to the climate change, the leaves may dry up because of the low temperature.

Solution: pay attention to the weather change in real time. If the temperature difference is large, it should be maintained indoors in advance. The change in room temperature is not as obvious as outdoor, and it has time to adapt to this climate change.

3. Bad environment

Rabdosia angustifolia has a certain adsorption capacity for dust and harmful substances, but if the environment is particularly bad, such as more dust and loud noise, so that the leaves are covered with dust, and usually do not pay attention to cleaning, it is possible that the photosynthesis of leaves is not smooth, then leaf drying is easy to occur.

Solution: often use sprayers to spray water to the leaves, pay attention to keep the leaves clean and clean, and keep the environment transparent enough to allow it to carry out normal photosynthesis, then the dry problem can be fully improved.

4. Nutrient deficiency

The management of Rabdosia angustifolia can be relatively extensive, and its demand for fertilizer is not high, but in the early stage, the soil is more fertile, and some fertilizers are added at an appropriate time, on the contrary, if the soil is relatively barren and fertilize less, the leaves will dry up because of the lack of nutrients.

Solution: the soil is mainly relatively fertile acid soil, such as river soil, garden soil, etc., if the soil quality is general, you can also plant some livestock dung at the bottom, and then supplement some urea at the growth stage.

Hydroponic culture, culture and reproduction methods of Rabdosia angustifolia source author: Li Mu 2012-04-26 popularity: 1530 I will pick the wrong copper grass, also known as water money, like wet environmental conditions, suitable for aquarium, aquarium, pool or wetland growth: not strict environmental requirements, in a humid environment is better, suitable for aquatic. Growing in the direction of light, it is easy to tilt the crown and grow only.

Cultivation method: half water and half soil is the best, followed by soil culture, but also water culture. Because hydroponics is clean, many flower lovers choose hydroponics to introduce some hydroponic experiences below. 1. Water money is suitable for extensive cultivation, as long as it is given enough sunshine and water, it can grow very fast. two。 If there is no sunshine indoors, lights can be used instead. 3. Water needs to precipitate tap water for two hours, or use 4. 5% every other day. You can add a little nutrient solution to the water. 5. Water money generally has yellow leaves, but its withering rate is far less than the growth rate, so don't worry. 6. The root system of water money grows green algae, but can not be cleaned. 7. As long as the water is not rotten, just add water to it, and often spray some water on the leaves ~ with the warmer weather, you can now buy some lovely copper grass to nourish it ~ of course, the higher level of water-raised plants is to do scene design. Water money is easy to raise ~ is also a common collocation for scenery. Author: Wang Fei 2012-04-26 popularity: 15943 I will pick the wrong-Tongqian grass, also known as mushroom grass, is a perennial water or wet herb. The plant height is 5cm to 15cm. The top of the stem is brown. Submerged leaves with long stalks, round peltate, 2-4 cm in diameter, margin undulate, grass green. Flowers bisexual; umbels; florets white and pink. Divide the fruit. The florescence is from June to August. Its stem node is obvious, a section, each section has a leaf, can be extended all the time. Its underground stem grows at an astonishing rate and spreads wherever it goes. It is one of the beautiful and easy-to-grow aquatic plants. This kind of plant can be planted in open fields in warm areas. it is suitable for indoor water greening in water trays, aquariums, pools, and wetlands. When cultivated in an aquarium, it is often used as a foreground grass. The whole herb can be used as medicine and has the effect of diuresis. If you want to use potted or hanging pot cultivation, it is best to keep water for a long time.

Breeding method: the requirement of water quality of Rabdosia angustifolia is not strict, it can be cultivated in fresh water with low hardness, 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). Codonopsis lanceolata likes the environment with sufficient light, and the plant grows poorly in shade environment. Its full-day growth is good, its petiole will be longer in half-day light, and its posture will be more beautiful if it grows in the direction of light. It is best to let it receive 4-6 hours of scattered sunlight every day; using a special fluorescent lamp, the plant can grow normally when given artificial light for 8-10 hours a day. It likes warmth and is afraid of cold. It grows well in the temperature range of 10-25 ℃, and the overwintering temperature should not be lower than 5 ℃. Under good management conditions, Rabdosia angustifolia is not prone to disease and is less attacked by harmful animals. This kind of plant is perennial, it grows quickly and takes shape quickly. In the case of not turning the pot, the formed plants should not be planted continuously for more than 2 years, otherwise the growth of Lentinus edodes will become weaker and weaker. Other: Tongqian grass likes to be warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, regardless of cultivated soil, soft and well-drained cultivated soil is better, and the optimum water temperature is 22-28 degrees. Shade-resistant, moisture-resistant, slightly drought-resistant, highly adaptable, amphibious. What to do about the yellowing of the leaves of Rabdosia angustifolia: there are roughly several reasons for yellowing: 1, watering "half of the water", that is, watering is not thorough, there is water seepage at the bottom of the basin. 2. The root system has been frostbitten when it is cold in winter. 3, after the winter, eager to go out of the room, put in a warm place to bask in the sun, temporarily unable to adapt to the abrupt climate. 4. The basin soil has been too wet or too dry for a long time. 5. Put it in the environment of poor ventilation for a long time. 6. The leaves were not cleaned with water for a long time, and dust accumulated, which hindered photosynthesis. Breeding experience: Tongqian grass leaves round wavy edge, long stem, summer and autumn open a small yellow-green flowers, land and water can be farmed. Like warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, regardless of cultivated soil, soft and well-drained cultivated soil is better, the optimum water temperature is 22-28 degrees. Propagation can be done by ramet or cuttage, which is easy to cultivate, keep the cultivated soil moist, and root in about 1-2 weeks. Because the plant is moisture-tolerant and watery, it is also suitable for cultivation in water basin and pool. If aquaculture, be sure to change the water every week and add a special nutrient solution for foliage plants. Figure 2 shows the water-raised copper grass. The two pots of copper grass that have just been planted are a little sick. I hope they will get used to the new environment and grow crazy as soon as possible. Author: Wang Fei 2012-04-26 popularity: 1071 I will pick the wrong propagation method: this plant is mainly propagated by split-plant method or cutting method, which is mostly carried out in March to May every year. It is easy to cultivate and keep the cultivated soil moist. It will take about 1 to 2 weeks to root. The 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 of Rabdosia angustifolia is formed. Medium-sized flowerpots without drainage holes are often used as planting containers. In order to obtain a better ornamental effect, one human 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. Many people in ★ use it as water to raise plants, but in fact, some hydroponic plants grow better in soil than in hydroponics, so do coppergrass. You can plant it in the soil, and then you can see more sunshine but not in the sun. Water it once in the morning and evening, and use light fertilizer if you want to fertilize it. ★, which is not strict in water quality, can be cultivated in fresh water with low hardness. It has strong adaptability to pH of water body, but it is best to control it at 6.5 ~ 7.5 Q, that is, it can grow well in slightly acidic to slightly alkaline water. It has a large demand for fertilizer, and it can be topdressing every 2-3 weeks in the vigorous growth stage. When the plant differentiates into flower buds, phosphate fertilizer can be applied appropriately. The money grass likes the environment with plenty of light, and the leaves of the shaded plant are easy to rot, so it is best to let it receive more than 4 hours of scattered sunlight every day. You can also use a special fluorescent lamp, and the plant can grow normally when given artificial light for 8 to 10 hours a day. It should be noted that when the light is strong, the plant begins to grow laterally, while when the light is weak, the plant begins to grow upward. It likes warmth, avoids high temperature and resists low temperature. It grows well in the temperature range of 16-24 ℃, and the overwintering temperature should not be lower than 5 ℃. When the water temperature exceeds 30 ℃, the plant growth will be inhibited. Under good management conditions, it is not easy to get sick and is less attacked by harmful animals. ★ copper money grass is quite easy to raise, first cut off the dry leaves, that is, it is relatively close to the soil, leaving about 1 centimeter or so, it will continue to grow, and people who have raised copper money grass will recommend half soil and half water, because that is the fastest growth rate, and it will grow crazy as long as there is water and sun. ★ is a plant that can be planted in open fields in warm areas. it is suitable for indoor water greening in water trays, aquariums, pools, and wetlands. When cultivated in an aquarium, it is often used as a foreground grass. The whole herb can be used as medicine and has the effect of diuresis.

Tongqian grass leaves round wavy edge, long stem, summer and autumn open small yellow-green flowers, land and water can be farmed. Like warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, regardless of cultivated soil, soft and well-drained cultivated soil is better, the optimum water temperature is 22-28 degrees. Propagation can be done by ramet or cuttage, which is easy to cultivate, keep the cultivated soil moist, and root in about 1-2 weeks. Because the plant is moisture-tolerant and watery, it is also suitable for cultivation in water basin and pool. If aquaculture, be sure to change the water every week and add a special nutrient solution for foliage plants. Tongqian grass does not need a large basin, can also be planted in a larger bowl, daffodil pots can also be used to raise daffodils, soil with general vegetable garden soil, an appropriate amount of mixed with some river sand, which add a small amount of organic fertilizer as base fertilizer. Money can be planted flat when the money is planted, it is better to cover the rhizome slightly and not to 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. Tongqian grass is afraid of the cold. If you put it outside in winter, you can pour out all the water. If you put it in a place facing south and leeward, you can survive the winter safely, but some of the leaves will die, 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, pour out the water and keep it moist. As long as the room temperature is not lower than zero, it will continue to grow in the coming year. Leaves hair brass money grass leaves yellow how to do: there are several reasons for yellowing: 1, watering "half of the water", that is, watering is not thorough, there is no water seepage at the bottom of the basin. 2. The root system has been frostbitten when it is cold in winter. 3, after the winter, eager to go out of the room, put in a warm place to bask in the sun, temporarily unable to adapt to the abrupt climate. 4. The basin soil has been too wet or too dry for a long time. 5. Put it in the environment of poor ventilation for a long time. 6. The leaves were not cleaned with water for a long time, and dust accumulated, which hindered photosynthesis. The general way to raise money is that the effect of half soil and half water is the best and the sun is big. However, today, inadvertently from the Baidu encyclopedia to see that copper grass is a shade-loving plant, which makes me doubt my own way of breeding. The following is an excerpt from Baidu. Let's study and discuss it together to see how we all raise money: [copper money grass] Copper money grass likes to be warm and humid, it is better to cultivate in half-day sunshine or shade, avoid direct sunlight, and the cultivated soil is free. Soft and well-drained cultivated soil is the best, and the optimum water temperature is 22-28 degrees. Shade-resistant, moisture-resistant, slightly drought-resistant, highly adaptable, amphibious. The plant height is 5cm to 15cm. The top of the stem is brown. Submerged leaves with long stalks, round peltate, 2-4 cm in diameter, margin undulate, grass green.
