How to Care for the Dracaena Fragrans 'Spike'
The Dracaena fragrans 'Spike' is loved by succulent enthusiasts for its unique shape and robust vitality, but to grow a sturdy and upright plant, one must master scientific care methods. This article will systematically analyze the five key points of caring for the Dracaena fragrans 'Spike', from soil selection to daily management.
Analysis of Core Care Points
Substrate Formula Determines the Basis of Survival
It is recommended to use a formula with 70% granular soil (akadama soil + volcanic rock + coconut fiber), ensuring that the substrate porosity is >35%. Add bone meal as a base fertilizer when repotting in spring every year. Clayey soil needs to be mixed with coarse sand to improve drainage, preventing root rot during the rainy season.
Light Intensity Affects the Development of the Plant Shape
In spring and autumn, ensure 6 hours of direct sunlight per day, and provide appropriate shading between 11-15 points in summer. Insufficient light can cause the column to become thin and elongated; it is recommended to rotate the pot 180° every half month to ensure even light exposure. In winter, use a plant growth light to maintain a light intensity of 3000-5000 lux.
Scientific Water Control for Root Care
Adopt the "dry-wet alternating method": in the growing season of spring and summer, water thoroughly after the potting soil is completely dry, and keep the substrate slightly dry in winter. It is recommended to use the bamboo stake test method—insert it 2/3 into the potting soil, and if there is no trace of moisture when pulled out, water补充. Accumulated water in trays during the rainy season should be drained promptly.
Accurate Fertilization Promotes Growth
Apply cactus-specific fertilizer (N-P-K=2-7-7) every month during the growing season, with a diluted concentration of 1200-1500 times. Stop applying nitrogen fertilizer in the second half of September and switch to potassium dihydrogen phosphate solution for root irrigation (1:2000) to enhance the plant's cold resistance.
Advanced Care Techniques
In winter, maintain an environment above 8°C, and spray to increase humidity once a month when the air humidity is below 40%. If scale insects are found, they can be physically removed with a 75% alcohol cotton swab, and spray 800 times the liquid of mancozeb in the early stage of (T-J) disease. Mature plants can be encouraged to produce lateral buds by cutting off the top.
By adopting a three-in-one care strategy of soil improvement, light control, and precise water and fertilizer management, combined with seasonal special care, the Dracaena fragrans 'Spike' can maintain an upright shape with an annual growth of 10-15 cm. It is recommended to take regular photos to record the growth status and gradually form a personalized care plan.
