How to Fertilize a Fortune Tree in Spring
The revival of all things in spring is the golden period for the growth of fortune trees. Scientific fertilization directly affects the annual growth trend. Mastering the rhythm and skills of nutritional supplementation can make the plant stems sturdy, leaves glossy and full, laying a solid foundation for healthy growth throughout the year.
Selection and Proportion of Fertilizers
Nitrogen-Dominant Fertilizers
In the stage of new bud germination, prioritize using compound fertilizers high in nitrogen content (recommended nitrogen-phosphorus-potassium ratio of 3:1:2), and the decomposed cake fertilizer needs to be fermented for more than 30 days. When using liquid fertilizer, maintain a dilution ratio of 1:800 with water to avoid burning tender buds with high concentration.
Techniques for Supplementing Trace Elements
Add slow-release fertilizer granules containing calcium and magnesium every month, which can effectively prevent the yellowing of leaf tips. It is recommended to use organic fertilizers containing humic acid, which can simultaneously improve the soil granular structure.
Nutrient Soil Preparation During Repotting
Substrate Improvement Plan
During repotting, retain 50% of the original soil + 40% new nutrient soil + 10% bone meal, mixed to form a breathable and nutrient-retaining slightly acidic substrate. The bone meal needs to be sterilized at high temperatures to avoid carrying pathogens.
Root Protection Operations
Control water for 3 days before removing the pot, cut off the rotting roots, and soak in a carbendazim solution. Place in a shady and well-ventilated area to recover after repotting, and resume fertilization after new leaves sprout.
Fertilization Cycle and Dosage Control
Dynamic Adjustment Strategy
Fertilize every 12 days from March to April, and shorten to 7 days apart in May. Pause fertilization when the temperature is below 15°C, and delay operations during rainy weather. Use the annular trench method for solid fertilizers, with an optimal distance of 8-10 cm from the main stem.
Precise Dosage Calculation
For a 20cm diameter pot, the amount of liquid fertilizer should not exceed 200ml each time, and granular fertilizer should be controlled at 3-4 grams. Use the bamboo stake test method: insert the stake into the pot soil 3 days after fertilizing, and pause watering if the stake is moist.
