Without adequate fertilization, Kalanchoe plants may exhibit stunted growth, pale leaves, and reduced flowering.
Suitable Fertilizers
A balanced, water-soluble fertilizer formulated for flowering plants is generally ideal. Look for fertilizers with a balanced NPK ratio (Nitrogen, Phosphorus, and Potassium). A ratio like 10-10-10 or 20-20-20 is suitable. Alternatively, fertilizers specifically designed for succulents and cacti can also be beneficial, as Kalanchoes share some similarities with these drought-tolerant plants.
Fertilizing Schedule
A regular feeding schedule is essential for optimal growth and bloom production. During the active growing season (spring and summer), fertilize every two to three weeks with a diluted solution. Reduce the frequency to once a month during the dormant period (fall and winter), or cease fertilizing entirely if the plant is exhibiting signs of stress. Adjust the schedule according to the plant’s needs, as observed through its growth and health.
Creating a Custom Schedule
The specific fertilization schedule for your Kalanchoe should be tailored to its size and growth stage. Young plants may benefit from less frequent fertilization compared to mature plants. Consider the plant’s overall health, vigor, and growth rate when making adjustments to the schedule. If the plant appears stressed or not thriving, reduce the frequency or concentration of the fertilizer solution.
Negative Effects of Over-Fertilizing
Over-fertilizing can have detrimental effects on your Kalanchoe. Excess fertilizer salts can accumulate in the soil, leading to nutrient burn, characterized by leaf discoloration and browning. This can also inhibit the plant’s ability to absorb water, further stressing the plant and potentially causing irreversible damage. Monitor your plant carefully for any signs of over-fertilization and adjust your feeding schedule accordingly.
Start with a weaker solution than you think is needed, and increase concentration only if the plant continues to show signs of under-feeding.
Examples of Fertilizer Ratios
A balanced fertilizer like 10-10-10 provides equal amounts of nitrogen, phosphorus, and potassium. A fertilizer with a higher phosphorus content (e.g., 15-30-15) might be better for encouraging blooms. A specific fertilizer designed for succulents might contain a lower nitrogen content and a higher phosphorus content, tailored to the needs of the plant.
