Hoya Kerrii, also known as the sweetheart plant, is a popular houseplant loved for its heart-shaped leaves and charming appearance. Proper fertilization is essential to keep it healthy and promote lush, vibrant foliage. But how often should you fertilize your Hoya Kerrii?
Understanding Your Hoya Kerrii’s Nutritional Needs
Hoya Kerrii is a slow-growing succulent that prefers balanced, diluted nutrients. It naturally thrives in well-draining soil with minimal fertilization. Over-fertilizing can lead to salt buildup and damage to the roots, while under-fertilizing may result in weak growth and pale leaves.
Recommended Fertilization Schedule
During the active growing season, typically spring and summer, fertilize your Hoya Kerrii once a month. Use a balanced liquid fertilizer diluted to half strength to prevent overfeeding. In fall and winter, reduce fertilization to once every two or three months or stop altogether, as the plant enters dormancy.
Choosing the Right Fertilizer
- Balanced liquid fertilizer (10-10-10 or 20-20-20)
- Diluted to half the recommended strength
- Or a fertilizer formulated for succulents and cacti
Application Tips
- Apply fertilizer when the soil is moist to prevent root burn
- Avoid fertilizing during periods of stress or after repotting
- Ensure proper drainage to prevent waterlogging
Signs You Need to Adjust Fertilization
If your Hoya Kerrii shows signs of nutritional deficiency, consider adjusting your fertilization routine. Look for these indicators:
- Pale or yellowing leaves
- Weak or spindly growth
- Leaf drop or slow development
In such cases, increase fertilization slightly or switch to a more balanced nutrient mix, always ensuring not to overdo it.
Conclusion
Fertilizing your Hoya Kerrii once a month during the growing season with a diluted, balanced fertilizer promotes healthy leaves and vigorous growth. Adjust your routine based on the plant’s response and environmental conditions to keep your sweetheart plant thriving.
