How often to fertilize succulents
Many succulent enthusiasts encounter challenges with fertilizing during the care process. These plants require nutrients to support growth but are easily damaged by excessive fertilization. By observing the growth cycle and variety characteristics, it is possible to find a scientific fertilizing schedule.
Correlation between fertilizing time and seasons
Difference between summer and winter types
Crasulaceae, Euphorbiaceae, and other summer types enter the growing period from May, and applying diluted liquid fertilizer every 15 days is optimal. For winter types like Aizoaceae and Haworthia, fertilizing should start after the temperature cools down in September, maintaining a 15-day interval.
Special treatment during dormancy
When the temperature exceeds 32°C or drops below 10°C, most varieties enter a dormant state. Fertilization should be completely stopped at this time to avoid root burn. This can be judged by observing the leaf condition: thin new leaves and withered old leaves are signals that require fertilization.
Three key aspects of fertilizer application
Selection of nutrient element ratio
A balanced 10-10-10 compound fertilizer is the safest choice, and combining it with organic fertilizer that contains trace elements is even better. The dilution concentration of liquid fertilizer should be controlled at 1/2 of the instructions on the packaging, and the amount of granular slow-release fertilizer should not exceed 3% of the potting soil volume.
Technique for mixing base fertilizer
When repotting, mix decomposed sheep manure with red clay soil at a ratio of 1:15, and keep the amount of bone meal to 5% or less of the total substrate. Volcanic rock particles can improve aeration, and combining them with 2% wood ash can adjust the pH level.
Key points of top-dressing operation
Stop watering 3 days before fertilizing, and loosen the soil to a depth of 2-3cm when the potting soil is half-dry. Pour the fertilizer solution around the edge of the pot, avoiding contact with the base of the stem. Maintain ventilation for 48 hours after fertilizing, and provide shading during intense sunlight.
By establishing a fertilizing system that aligns with seasons, varieties, and growth stages, and by using the correct operation methods, it is possible to ensure the healthy growth of succulents and prevent fertilizer damage. It is recommended to create a fertilizing calendar to record each operation and adjust dynamically based on the plant's condition to gradually form a personalized care plan.
