What about the rotten leaves of Pennisetum

If it is not properly maintained, it is easy for the leaves to turn yellow and wither, and the whole plant slowly becomes wilted and rotten. Generally, it is caused by three reasons:

1. Watering half cut-off water: watering only half cut-off water. Insufficient root water absorption will lead to yellow leaves, rotten leaves, small leaves and no luster

Solution: when watering, follow the principle of dry through watering until there is water seepage at the bottom of the basin

2. Airless and breathable: green leafy plants like Pennisetum like the most ventilated and breathable environment. Too dense leaves, airtight soil and big rotten roots will also cause the leaves to turn yellow and rot

Solution: for indoor maintenance of copper coin grass, it is best to put it on the windowsill with bright light, often open the window for ventilation, and trim the useless branches and leaves in time

3. Insufficient nutrients: the leaves of water cultured Pennisetum turn yellow and rot, which is generally caused by insufficient nutrients in the water; When half soil and half water is maintained, it propagates too fast and the stems and vines fill the basin, which will cause the oxygen content in the basin to be too low and the plants to wilt and rot the leaves

Solution: the water must be changed frequently and some old plants should be cleaned properly; Half soil and half culture grow faster. Once the basin is full, replace it immediately

What about the rotten leaves of water lilies

Water lilies like a warm, humid and sunny environment. Generally, rotten leaves are caused by three reasons

Solution

1. Increase water supply: the water level is properly deepened in summer, and the water level is gradually increased with plant growth; Change the water every 3 ~ 5 days. Water lilies like high air humidity. They should often spray water around the plants

2. Ensure sufficient light: water lilies like light. Water lilies cultivated in pots and tanks must be placed in a place with sufficient light to receive full light

3. Disease control: in summer, water lilies are easy to be infected with black spot and brown spot. Yellowish brown spots will appear on the leaves and gradually expand, resulting in black and rot of the leaves

When infectious diseases are found, the infected stems and leaves should be cut off in time. In serious cases, 75% chlorothalonil 600 ~ 800 times solution can be sprayed for control

What about the rotten leaves of Fugui bamboo

Fugui bamboo likes shade and humidity, and is resistant to waterlogging and fertilizer. If it is maintained in summer and does not pay attention to light, water and fertilizer, it is easy to cause the leaves to turn yellow and rot, especially the newly bought Fugui bamboo

1. Too strong light: Fugui bamboo is resistant to half shade. Too strong light and exposure to the sun will cause the leaves to turn yellow and wither

Solution: cut off the dead leaves and yellow leaves, place the indoor maintenance at the scattered light with bright light, and shade the outdoor maintenance

2. Insufficient water: Fugui bamboo likes water and is resistant to waterlogging. Insufficient water will cause dry tip and yellowing of leaves; Hydroponic Fugui bamboo without changing water for a long time will also cause leaf rot

solution: in summer, sprinkling water once a day and early in the morning to keep basin soil moist, spray water and spray frequently on the leaves, and maintain a higher air humidity. The water should be changed every 7 ~ 10 days

3. Poor air permeability: if the pots and soil are not changed for a long time, the soil will harden, resulting in poor root respiration and rotten roots, making the leaves rot quickly

Solution: cut off rotten and dead leaves and loosen the basin soil regularly. If the fertility is insufficient, you can apply less rotten organic fertilizer

What about rotten leaves of white palm

White palm likes the semi shade environment with high temperature and humidity. If it is not maintained properly in summer, it is most likely that the leaf tip is blackened and decayed slowly, either with large water or hypertrophy

1. Waterlogging roots: white palm likes water, but frequent watering will cause ponding in the basin and rotten roots, resulting in rotten leaves

Solution: after waterlogging roots, take out the plants from the flower pot, cut off the rotten roots, disinfect and dry them, and then put them in the pot again

2. Hypertrophic root burning: avoid thick fertilizer and raw fertilizer. If it wilts just after fertilization, it means that fertilization is too thick and too much, which will burn the root system and directly lead to the decay of the whole plant

Solution: after hypertrophy, water more and put it in a cool place slowly; If it is serious, dig out the whole white palm immediately and change the basin and soil again. In summer, it is only necessary to apply a thin liquid fertilizer once a month

What about the rotten leaves of green pineapple

Green pineapple is a relatively easy to raise water loving and shade tolerant plant. The rotten leaves are generally caused by poor ventilation or infectious diseases

1. Poor ventilation: in summer, many flower friends like to spray water on the leaves of lvluo. If the indoor ventilation is not good, the air permeability is poor, and the water on the leaves cannot evaporate in time, it will cause rotten leaves

Solution: cut off the rotten and yellow leaves, open more windows for ventilation, and trim the dense branches and leaves in time

2. Infection disease: Green pineapple is easy to be infected with anthrax. Reddish brown or dark brown spots appear in the middle of the leaves, which gradually expand, resulting in blackening and falling off of the leaves

Solution: first cut off the diseased leaves, and then spray carbendazim or metobuzine solution diluted 500 ~ 1000 times on the diseased place. Spray it once every 1 ~ 2 days, and it can be seen that it is good after 3 ~ 4 times
