Do you have a large-flowered cymbidium at home? Isn't it beautiful enough to make your heart skip a beat? However, making it thrive is not as simple as it seems. Today, let me reveal the "delicacy" of the large-flowered cymbidium—what kind of soil to use for growing it!
Did you know that the large-flowered cymbidium has very high requirements for soil? Ordinary potting soil has poor drainage and permeability, which may cause its roots to rot and affect growth. Therefore, we need to prepare a "delicacy" for it—a loose, breathable, well-drained fertile sandy soil.
Soil Secrets Revealed: Homemade vs. Purchased
1. Homemade Soil: You can mix leaf mold, moss, bark chunks, fern roots, and broken bricks, or you can formulate it using peat soil, brick particles, sawdust, and fern roots. Mixing these materials together will provide a cozy home for the large-flowered cymbidium.
2. Purchased Soil: There are specially designed soils for orchids on the market, which have better drainage and permeability and are more suitable for the growth of large-flowered cymbidiums.
Soil Mixing: Ratios and Techniques
1. Ratio: Generally speaking, the ratio of leaf mold, peat soil, and perlite is 4:3:3, which provides both breathability and drainage.
2. Technique: When formulating the soil, pay attention to fully mixing the materials to ensure uniformity.
Planting Large-Flowered Cymbidium: Pot and Preparation
1. Pot: Large-flowered cymbidiums prefer tall pots; clay pots and ceramic pots are good choices. The diameter of the pot should be around 15-20 cm.
2. Plant Preparation: Before planting, carefully arrange the roots of the large-flowered cymbidium, trim off old and rotten roots, and thin out overly dense roots. Soak in carbendazim solution for disinfection, and also appropriately thin out branches and leaves to reduce water and nutrient consumption.
Planting Large-Flowered Cymbidium: Steps and Precautions
1. Steps: Lay some broken bricks at the bottom of the pot, then fill in the prepared soil, and subsequently plant the large-flowered cymbidium. Plant 2-4 seedlings per pot, press firmly, and water thoroughly.
2. Precautions: After planting, place the large-flowered cymbidium in a cool, shaded area to allow it to gradually adapt to the new environment.
Watering and Fertilizing: The "Diet" of the Large-Flowered Cymbidium
1. Watering: Large-flowered cymbidiums like moisture and require regular watering during cultivation. In summer when temperatures are higher, water once daily; in winter, water every 5-7 days.
2. Fertilization: During the growth period, apply compound fertilizer every 15 days; during the flowering period, apply phosphorus and potassium fertilizer.
Light and Temperature: The "Living Environment" of the Large-Flowered Cymbidium
1. Light: Large-flowered cymbidiums prefer diffused light; when sunlight is too strong in summer, shading measures are needed.
2. Temperature: The optimal growth temperature for large-flowered cymbidiums is between 10-25 degrees Celsius.
Pest and Disease Control: The "Health Guardian" of the Large-Flowered Cymbidium
1. Diseases: Large-flowered cymbidiums are prone to leaf blight, anthracnose, soft rot, and leaf spot. These can be controlled with 500 times dilution of 50% methane or 50% carbendazim.
2. Pests: Main pests include aphids, spiders, and silkworms. They can be controlled with 1000 times dilution of each of the emulsifiable concentrates of phoxim and oxidant.
After saying so much, do you now have a deeper understanding of how to cultivate large-flowered cymbidiums? Hurry up and prepare a delicious "delicacy" for your large-flowered cymbidium so that it can grow vigorously and bloom beautifully!
