Method of Cultivating Calla Lilies
As an elegant ornamental plant, the Calla Lily is popular in home greenery due to its unique spathe shape. To make this Araceae plant bloom in a home environment, it is necessary to master key cultivation techniques such as temperature control and lighting management. The following text will provide a detailed analysis of the entire process from pot selection to daily maintenance.
Pot Selection and Soil Mixing Plan
Standard for Breathable Pots
It is recommended to use a terracotta pot with a diameter of over 30cm, with 3-5 drainage holes at the bottom. Mix peat soil and perlite in a 4:1 ratio to ensure the roots are well-drained and ventilated.
Light Requirements and Placement Techniques
Seasonal Light Adjustment
In spring and autumn, expose to 6 hours of direct sunlight daily, use a 40% shade cloth for protection in summer. In winter, place it 1 meter away from the south-facing windowsill to supplement light through reflected light.
Temperature Control Plan
Overwintering Anti-Cold Measures
Maintain an ideal growth temperature of 16-25°C and move it indoors before frost. Use double-glazed windows combined with a humidifier to keep the environmental humidity above 60%.
Scientific Watering Method
Humidity Control Techniques
Water twice a week using the immersion pot method, and use a spray bottle to moisten the leaves in the morning and evening. Use softened water with an EC value less than 0.5 to avoid soil salinization.
Dividing and Pests and Disease Control
In spring, divide the corms during pot changing, keeping at least 3 buds. Regularly check for red spider mite infestations and use neem oil for biological control.
By accurately controlling temperature and humidity, properly mixing soil, and scientifically managing lighting, Calla Lilies can bloom throughout the year. It is recommended to apply phosphorus-potassium fertilizer monthly to promote bud differentiation, and combine pruning of old leaves to maintain an attractive plant shape, allowing this elegant plant to continuously add natural vitality to the living space.
