How does gentleman orchid grow spot to do?

When the phenomenon of long spots appears in the maintenance of Cymbidium, it needs to be solved by prescribing the right medicine. If the basin soil is not suitable, the soil should be changed in time; the light should be shaded if the light is too strong, and the light should be replenished if the light is insufficient; water should be controlled if too much water is watered, and water should be replenished if there is too little water; if there is too much fertilizer, we should water and dilute it, and if there is too little fertilizer, we should topdressing in time; we should also pay attention to disease prevention and control and maintain a ventilated environment.

1. Change the basin soil

If the soil of Cymbidium is too moist, it will make its roots in a moist environment for a long time, breeding bacteria will lead to long spots; and the lack of soil nutrition is not suitable for the growth of Cymbidium will also lead to its long spots. It is necessary to change the planting soil in time and choose loose, fertile and slightly moist new soil for planting.

2, pay attention to the illumination of the magnolia because of long-term exposure to the sun or lack of sunlight in the dark for a long time, which leads to it? Need to pay attention to light maintenance in time, if the sun is too strong, move to a cool and ventilated area for maintenance, and if there is a lack of sunlight, put it into the sun scattering area to receive sufficient sunlight.

3. Proper watering

Too much watering will lead to stagnant water in the basin, and the root rot of Cymbidium will begin to grow spots, while too little watering will also lead to insufficient water for growth, resulting in long spots. To timely watering maintenance, watering too much should pay attention to water control, keep the soil slightly wet, watering too little should be timely watering, to replenish water.

4. Rational fertilization requires enough fertility to grow in the growth process, but too much fertilizer will make it burn roots and grow black spots, and too little fertilizer will make it malnourished. Need to pay attention to rational fertilization, too much fertilizer on watering dilution, so that the fertility becomes weak, too little fertilizer is timely topdressing, pay attention to the application of thin fertilizer.

5. Disease control of Magnolia lanceolata may also be due to leaf spot disease, which leads to spots on the leaves, which requires timely disease control. It is necessary to remove the diseased leaves first, and then spray carbendazim solution or chlorothalonil solution for sterilization and disinfection to do a good job in disease prevention and control.

6. Keep ventilated

Cymbidium grows in a poorly ventilated environment, and the air is difficult to flow, which can easily lead to the growth of bacteria and the phenomenon of long spots caused by bacterial infection. It is necessary to do a good job of ventilation in time, trim its leaves and put them in the ventilation area, so as to make the orchid grow better in the ventilation environment of air flow.
