How to plant Caladium seeds to germinate
About how to plant Caladium seeds to germinate and the gardening tips for Caladium care, the specific introduction is as follows:
One: Caladiums prefer a warm climate, are intolerant to cold and high temperatures, and the optimal growth temperature is around 20°C. At 0°C, the rhizomes will freeze and die. They require plenty of sunlight in winter, as insufficient light results in fewer flowers, but they are somewhat shade-tolerant. In summer, when the sun is too intense, provide appropriate shading. They like moisture and slightly积水 does not greatly affect growth, but they are not drought-tolerant. They thrive in loose, fertile, humus-rich clayey soil. Propagation is mainly through division of bulbs. After the plant enters dormancy, the small bulbs around the rhizome are removed and planted separately. Seed propagation is also possible, with seeds sown in pots after maturity. The optimal germination temperature is around 20°C.
1. Pot and soil: Use a shallow pot instead of a cylindrical pot. The growing medium should be mainly sandy loam mixed with 1/3 garden soil and 1/3 leaf mold, and then mixed with 1/5 organic fertilizer. Since the roots grow on the upper part of the bulb, the bottom of the pot should be lined with permeable cinders or coarse sand.
2. Potting: When the bulb sprouts new leaves, choose a large, healthy bulb for potting. Place it in a greenhouse after October and it can bloom around the Spring Festival. However, be careful to prevent poor ventilation and excessive room temperature.
3. Fertilization: A lack of fertilizer or excessive fertilization can cause yellow leaves, so it's important to apply a base fertilizer. As the nutrient supply in potted plants is limited, it's necessary to apply thin and frequent fertilization.
4. Watering: Caladiums are known as "the不死 Caladium" because they prefer a warm and humid environment and are intolerant to drought. The potting soil should be kept moist and should not be short of water. If the environment is dry, spray water on the ground to maintain a humid micro-environment. Watering should be ample during growth and flowering periods. Keep the potting soil moist, but reduce watering after flowering to aid in dormancy.
5. Light: Pay attention to lighting during the flowering period. Caladiums "like long light but not strong light," especially avoiding direct sunlight in summer. Therefore, they should be placed in a well-lit area and moved further away from the window in summer. Insufficient lighting during the flowering period will cause only the buds to emerge without flowering, or the flower buds to gradually turn green and wither. There is no need to shade in spring, autumn, and winter.
Two, Precautions for raising Caladiums
1. Pruning: Caladiums are perennial herbs that can bloom multiple times a year. Regularly pruning old leaves can promote multiple blooming.
2. Caladiums' aversion to "smoke": Caladiums are sensitive to "smoke." Kitchen smoke and smoking can cause yellowing leaves and falling flowers, leading to poor growth.
3. Watering: Provide sufficient water (do not plant too shallowly; water when the soil dries out).
4. Drainage: The soil should have good drainage to prevent excessive moisture.
5. Temperature: Avoid high temperatures in the greenhouse, especially when relative humidity is high.
6. Prevent damage to the plant and bulb: Prevent wind damage to the plant and ensure that herbicides do not affect plant growth. Be careful during harvest and handling.
7. Prevent fungal diseases and pests: For example, damage caused by Pythium or Rhizoctonia.
