Cyclamen Fertilization Method
As a popular ornamental plant loved by flower enthusiasts, cyclamen has unique nutrient requirements. Scientific fertilization not only makes the leaves glossy and upright but also promotes bud differentiation. This article will systematically analyze the timing of fertilization, fertilizer type selection, and operational skills to help you cultivate精品 cyclamen with lush leaves and abundant flowers.
Key Points for Fertilization Cycle Control
1.1 Optimal Time for Potting Base Fertilizer
Every 2 years when repotting, be sure to mix well-rotted sheep manure or bone meal and other long-acting fertilizers into the substrate, which serves as an energy reserve for the entire year's growth. The best operational time is from March to April in spring, with the base fertilizer accounting for no more than 10% of the soil volume.
1.2 Top-dressing Rhythm During the Growing Season
From April to October, the peak growing season, it is recommended to top-dress once every 20 days. If the expansion speed of new leaves slows down, it can be shortened to every 15 days. Fertilization should be completely stopped when the temperature is below 15℃ in winter.
Scientific Proportion of Fertilizer Types
2.1 Organic Fertilizer and Compound Fertilizer Combination
Base fertilizer recommends a combination of well-rotted cake fertilizer and vermiculite (3:1), and top-dressing can use water-soluble fertilizer with nitrogen, phosphorus, and potassium (15-15-15). Adding monopotassium phosphate (1000 times liquid) during the budding stage significantly promotes flowering.
2.2 Special Nutrient Supplement Plan
Supplement with a solution of ferrous sulfate (0.2% concentration) once each in spring and autumn to prevent yellow leaf disease. Spraying a diluted beer solution (1:50) on the leaves can make the leaf vein patterns clearer.
Detailed Explanation of Correct Application Techniques
3.1 Operation Specification for Hole Application Method
Dig a 2cm shallow trench 5cm away from the base of the plant, evenly sprinkle 10-15 slow-release fertilizers, and cover with soil. Be sure not to let the fertilizer come into direct contact with the fleshy roots.
3.2 Key Points for Liquid Fertilizer Application
The dilution concentration should be reduced to 2/3 of the packaging instructions, and pour slowly along the edge of the pot. Avoid direct sunlight for 48 hours after fertilization, and combining with loosening the soil can enhance absorption efficiency.
Key Points for Special Period Maintenance
4.1 Fertilization Control During Dormancy Period
Immediately stop all fertilization operations when the environmental temperature is continuously below 12℃. At this time, the root absorption capacity decreases, and fertilization can easily cause fertilizer damage.
4.2 Emergency Treatment for Fertilizer Damage
If the leaf tip withers, immediately remove the pot and wash the roots, then soak in carbendazim before replanting in new soil. In severe cases of fertilizer damage, cut off 1/3 of the leaves to reduce transpiration.
By mastering these fertilization tips, combined with regular pot rotation, moderate sunlight, and other maintenance measures, your cyclamen will surely show an elegant posture. Flexibly adjusting the fertilization strategy at different growth stages is the key to cultivating精品 orchids.
