How to manage the seedling stage of Cymbidium?

After sowing, if the temperature and humidity are suitable, the orchid can take root in about a month and sprout in 50-60 days. After several years of careful maintenance, it can blossom for the first time in the fourth year; if it is not properly maintained, it may take 5 to 6 years to blossom.

The management of water and fertilizer is very important in the seedling stage, especially in the seedling stage. After the first transplant, watering should be dry and wet, in order to keep the basin soil moist. In the over-wet soil, the roots are easily rotten due to lack of oxygen, and the roots wilt and wither if they are too dry. The water quality of Rain Water, river water and pond water is better, and the tap water should be kept for a few days. If the water quality is too alkaline, you can drop a few drops of vinegar in the water to become acidic soil.

After 3-4 weeks of potting, the seedlings of Cymbidium begin to use liquid fertilizer with a concentration of 15%-20%, applying fertilizer every 10-15 days, using fully mature cake fertilizer and water; you can also apply a few pieces of urea at the edge of the basin to absorb the roots by watering, and avoid applying raw fertilizer and thick fertilizer to avoid plant damage. When the seedlings grow to 5 or 6 leaves, that is, they enter the period of vigorous growth, they need to supply sufficient water and fertilizer to meet the needs of continuous growth. Gradually increase the watering times and the amount of water, increase the times of fertilization and the concentration of liquid fertilizer.

It was watered once a day in spring and autumn, once or twice a day in summer, and once from winter to early spring. In short, in order to keep the basin soil moist, in addition to using horseshoe slices or cake powder and bone powder as base fertilizer when changing the basin, liquid fertilizer should be applied once a month, or special fertilizer should be applied once a month. Summer should pay attention to shading and ventilation, heat prevention and cooling.

Early summer can accept the first half of the day of light, the height of summer can only bear the sun before 9 o'clock. Spray the leaves and basin surface many times a day and sprinkle water to the ground to wash dust and cool down and increase air humidity. Winter must be placed on the sunny windowsill or closed balcony, the room temperature is not less than 5: 8 ℃. Pay attention to avoiding rain and waterlogging in the rainy season and try to keep it out of reach of the rain. In the whole seedling stage, as long as we change the basin timely, strengthen the management of water and fertilizer, and ensure the regulation of temperature and light, the plant will grow healthily and can blossom and watch in the fourth year.
