Hoya Kerrii, also known as the Sweetheart Plant, is a popular succulent known for its heart-shaped leaves. While it is generally easy to care for, yellowing leaves can be a sign of nutritional deficiencies or other issues. Choosing the right fertilizer can help restore its vibrant green color and promote healthy growth.
Understanding Yellow Leaves on Hoya Kerrii
Yellow leaves on Hoya Kerrii may indicate overwatering, poor soil drainage, or a lack of essential nutrients. Before selecting a fertilizer, it’s important to diagnose the cause. Often, nutrient deficiencies such as nitrogen, iron, or magnesium are responsible for yellowing leaves.
Top Fertilizers for Hoya Kerrii
Using the right fertilizer can help correct deficiencies and improve the overall health of your plant. Here are some of the best options:
- Balanced Liquid Fertilizer – A 10-10-10 or 20-20-20 formula provides essential nutrients evenly. Apply every 4-6 weeks during the growing season.
- Low-Phosphorus Fertilizer – Phosphorus can sometimes cause issues in succulents. A fertilizer with a lower phosphorus ratio (e.g., 10-5-10) supports healthy root and leaf development.
- Liquid Seaweed Extract – A natural option rich in trace minerals and growth stimulants. Use monthly for overall plant health.
- Iron Chelates – To combat chlorosis and yellowing caused by iron deficiency, apply iron chelate solutions as directed.
- Organic Compost Tea – Provides a gentle nutrient boost and improves soil health. Use as a foliar spray or soil drench.
Fertilizer Application Tips
Proper application maximizes benefits and prevents over-fertilization. Follow these tips:
- Always dilute liquid fertilizers according to package instructions.
- Fertilize during the active growing season, typically spring and summer.
- Avoid fertilizing when the soil is dry to prevent root burn.
- Reduce or stop fertilizing in the winter when the plant’s growth slows down.
- Monitor your plant regularly for signs of improvement or continued yellowing.
Additional Care Tips for Healthy Hoya Kerrii
Besides fertilization, ensure your Hoya Kerrii thrives by providing proper light, watering, and soil conditions:
- Light: Bright, indirect sunlight is ideal.
- Watering: Water only when the top inch of soil is dry.
- Soil: Use well-draining succulent or cactus mix.

With the right fertilization and care, your Hoya Kerrii can regain its lush, green appearance and continue to be a charming addition to your plant collection.
