How to Make the Dwarf Coconut Plant Grow More Leaves
As a representative of tropical ornamental foliage plants, the dwarf coconut is favored by indoor gardening enthusiasts for its tall, feathery leaves and elegant plant form. However, many plant lovers often encounter problems such as sparse leaves, yellowing, and dried leaves during the maintenance process. This article will systematically analyze the key elements that promote leaf growth and provide a complete solution for yellowing leaf issues.
Four Key Elements to Promote Dwarf Coconut Leaf Growth
1. Substrate Mixing and Root Care
The ideal potting soil recipe is recommended to use a mixture of humus soil: perlite: coconut bran in a ratio of 5:3:2, changing the substrate every 2 years and pruning 1/3 of the aging roots. Regular addition of EM bacterial agents can maintain soil microecological balance and promote the development of fine roots.
2. Temperature and Humidity Control
In addition to maintaining the optimal growth temperature of 20-25°C, it is necessary to use a humidifier to maintain 60%-75% air humidity. During the winter heating period,陶粒 (taoli, a type of ceramic stone) can be placed in a water storage layer in the tray to create a locally humid microenvironment.
3. Scientific Light Management
Receiving 4-6 hours of bright scattered light daily, and regularly rotating the plant 180° to ensure even light exposure. When using a lux meter for detection, maintain a light intensity of 8000-15000 lux, avoiding direct sunlight that may burn the leaves.
4. Precise Fertilization Plan
Use a 20-10-10 NPK water-soluble fertilizer during the growing season, applying an 800-fold solution every half month. Combined with monthly sprays of chelated iron foliar fertilizer, new leaves can increase by 30% and the leaf color will be darker and greener.
II. In-depth Analysis of Dwarf Coconut Yellowing and Drying Leaves
1. Root Abnormality Type Yellow Leaves
This is manifested by uniform yellowing of old leaves, often caused by root rot due to waterlogging. It is necessary to immediately remove the plant from the pot, expose the roots to air, cut off the blackened, rotting roots, soak in carbendazim for disinfection, and then replant in a more breathable red pottery pot.
2. Light Imbalance Type Burn
When brown burn spots appear at the leaf tips, the plant should be immediately moved to a location 1.5 meters away from an east-facing window. Severely burned leaves need to be pruned, and healing ointment should be applied to the wounds to prevent infection.
3. Low Temperature Frost Damage Type Wilted Leaves
When cold currents arrive in winter, in addition to maintaining a room temperature above 15°C, the plant can be covered with a thermal film at night and combined with the pot-in-pot method to enhance root insulation.
By establishing a maintenance log to record temperature and humidity changes, combined with regular leaf wiping, reasonable pruning, and other meticulous management methods, the dwarf coconut plant can maintain an ornamental state of 30-40 healthy green leaves per plant throughout the year. When the plant shows abnormal growth, timely comparison and adjustment of environmental parameters can effectively prevent various leaf problems.
