How to raise the potted grass (the method of overgrowing treatment) the method of fertilizing the potted grass

Potted grass is a kind of wet plant, which used to be common by the river, but now many people keep it at home, its value is very high, it can be used as medicine or ornamental, so it is deeply loved by people. However, many people are not very clear about its specific breeding methods when they are breeding.

How to raise the potted grass (the method of overgrowing)

1. Light and water treatment. If the potted grass appears to be in a state of overgrowth, quickly remove it from a cool and comfortable place, bask in the sun, carry out photosynthesis, and restrain its overgrowth. This is not enough, at this time the need to cut off water, although the growing season of potted grass needs water, but it is all in vain, do not aggravate its crazy growth momentum. It is not too late to carry out normal watering until the overgrowth of the plant is controlled.

2. Chopping cuttings. The branches of the potted grass grow a lot, but the overgrown branches are very thin, and the leaves are sparsely arranged and unattractive. At this time, it will be beheaded cutting, re-maintenance, is the best way. After beheading, the mother plant may even be able to kill two birds with one stone.

3. Dwarf and Zhuangsu. If the water and fertilizer management and light management are suitable, and the flower friends who do not want to cut their heads and cuttings, they can buy Daizhuangsu to apply to the weeping pot grass. After slowly restraining the growth, although the plant is not as beautiful as it is in the normal state, it can also recover by 80% to 90%.

Fertilization method of weeping potted grass

1. The choice of fertilizer: organic fertilizer, compound fertilizer and so on.

2. Fertilization method: fertilization should be carried out once when planting, but the concentration of fertilizer should not be too thick, and it should be watered in time after fertilization, so that the plant can absorb the beneficial ingredients of fertilizer more fully. Fertilization can be carried out every 15 to 20 days during the growing period.

3. Precautions: fertilization is suspended in winter, because it will enter a dormant state in winter, not only without fertilization, but also with a pause or a small amount of watering. Watering in time after fertilization can not only make plants better absorb nutrients in fertilizer, but also reduce the damage of fertilizer to roots. When fertilizing, it is best to slowly pour along the edge of the flowerpot, not near the root. Although the nitrogen in the fertilizer can make the plant grow faster, it is easy to overgrow if it is applied too much.

The reason for the growth of perpendicular grass

1. Lack of light. Spring, summer and autumn growing season, hanging pot grass can be maintained with scattered light, although to avoid direct light, but can not always be placed in the shade, otherwise it is easy to grow. And photosynthesis is not strong, the leaves will be white, yellowing, and even Zou Baba. Lack of light, the branches of the potted grass grow very slender, blowing in the wind distressing, like Lin Daiyu weak willow to support the wind.

2. Too much water. Pot grass is a water-loving plant, so it is necessary to keep the basin soil moist in daily maintenance. However, if the basin soil accumulates water for a long time, it is easy to cause futility. Especially during the rainy season in the Pearl River Delta, if the dewy grass is not removed in time, the plant is easy to grow crazy, but it is not strong.

3. Too much nitrogen fertilizer. Nitrogen fertilizer is the best to promote plant growth, but if excessive fertilization, it is easy to cause the overgrowth of potted grass.

Control of powdery mildew of Trifolium przewalskii

Powdery mildew. Symptoms: the disease sites are leaves, tender stems, flower buds and buds, etc., characterized by gray-white powdery mildew layer (conidia and mycelium of pathogens). The growth and development of the injured plants were hindered, the leaves were twisted, and the flowers could not blossom or become deformed. When the disease is serious, the leaves dry up and the plants die.

Pathogen analysis: the pathogen of powdery mildew is Polygonum powdery mildew, which belongs to ascomycetes subphylum. The mycelium is born on both sides of the leaf, conidia columnar, ascospores aggregated to nearly aggregated, dark brown, oblate, accessory filaments unbranched or irregularly branched, curved, ascospores long or short ovate, ascospores ovoid or elliptic.

Prevention and control methods: appropriate application of phosphate fertilizer and potassium fertilizer, pay attention to ventilation and light transmission. The seriously diseased plants or seriously diseased parts should be cut off, buried or burned in time, so as to put an end to the source of bacteria. 50% carbendazim wettable powder 800 times liquid, 80% Dysen zinc 500 times solution, 75% chlorothalonil 500 solution can be sprayed alternately.

Weeping pot grass in the breeding will also appear the situation of overgrowth, if there is a phenomenon of overgrowth, it is best to use the method of beheading to maintain. Weeping potted grass also has a lot of skills when fertilizing, and winter is its dormant period, so don't fertilize during this period.
