The Cultivation Methods and Precautions for Coral Grass
Among numerous indoor green plants, coral grass is favored for its unique feathery leaves and air purification ability. This succulent plant, native to the Mediterranean coast, has special requirements for its growing environment. Mastering the correct care methods can allow it to display its enchanting appearance. This article will systematically sort out the key points based on practical care experience.
Three Key Elements of Environmental Control
Soil Configuration Essentials
Use a mixture of perlite and peat soil in a 1:3 ratio, with a layer of ceramsite at the bottom for drainage. Add bone meal to supplement minerals when repotting every two years, and avoid using heavy garden soil. Test the drainage by pouring 500ml of water, which should fully penetrate within 20 seconds.
Light Adjustment Techniques
In spring and autumn, expose to 4 hours of scattered light daily, and use a shade net for protection between 10-15 hours in summer. In winter, place it 1.5 meters away from the south-facing window and use a grow light for 2 hours daily for better results.
Temperature and Humidity Management
Maintain an ideal temperature range of 15-25°C, and start a misting cooling system when above 30°C. Keep the air humidity between 40%-60%, monitor with a hygrometer, and avoid direct misting on the plant when using a humidifier.
Core Aspects of Daily Management
Scientific Watering Method
Use the "dry-wet cycle" method, insert a bamboo stake to 2/3 of the pot bottom, and water thoroughly when the stake pulls out white. In winter, water sparingly along the pot wall, ensuring the water temperature is the same as the room temperature to avoid stimulating the roots with cold water.
Precise Fertilizing Plan
Apply a water-soluble fertilizer with an NPK ratio of 6-12-6 every two weeks during the growing season, keeping the concentration at 800 times the liquid. In late autumn, apply monopotassium phosphate to enhance cold resistance, and avoid strong light exposure for 6 hours after fertilizing.
Special Period Handling
Propagation Operation Standards
The Cultivation Methods and Precautions for Coral Grass
Select a healthy top 5cm branch, let the cut end dry, and insert it into the vermiculite matrix. Maintain a constant temperature of 22°C, and using a bottom heating pad can increase the success rate. Gradually increase the light intensity after new leaves appear.
Disease and Pest Control
Regularly check the leaf undersides to prevent red spider mites, and use 75% alcohol wipes in the early stages. For root rot treatment, remove the necrotic tissue, soak in carbendazim solution, and then replant in new soil.
Seasonal Care Focus
Overwintering Protection Measures
Move indoors when the temperature drops below 10°C and set up a 30cm buffer zone away from the window. Rotate the pot 45 degrees weekly to maintain an even shape, and use a grow light for 4 hours daily.
Rainy Season Management Points
Start a dehumidifying device during continuous rainy weather, raise the pot bottom by 3cm to enhance ventilation, and pause foliar fertilizing, instead using granular slow-release fertilizer to maintain nutrient supply.
Through systematic care and management, coral grass can not only purify the indoor air but also become a unique home decoration. Regularly observe the plant's condition and adjust the care strategy in time, and you can also cultivate a healthy and lush coral grass landscape.
