Hoya kerri, also known as the Sweetheart Plant, prefers to be kept on the drier side. Allow the top inch of the soil to dry out before watering. When watering, ensure thorough saturation, allowing excess water to drain. Be cautious not to let the plant sit in standing water, as this can lead to root rot. Adjust the watering frequency based on the environmental conditions and the moisture level of the soil.
Provide bright, indirect light for your Hoya kerri. These plants thrive in moderate to bright light but should be shielded from harsh, direct sunlight. A north or east-facing window is ideal, ensuring they receive ample filtered sunlight throughout the day. If the leaves start to lose their luster or turn yellow, it may indicate too much light exposure.
Fertilize your Hoya kerri sparingly, typically every 2-3 months during the growing season (spring and summer). Use a well-balanced liquid fertilizer diluted to half the recommended strength. Avoid over-fertilizing, as this can harm the plant. During the dormant season (fall and winter), reduce or eliminate fertilization.
Hoya kerri doesn't require frequent repotting and prefers slightly cramped conditions. Repot only when the plant has outgrown its current container or when the soil has become depleted. Use a well-draining potting mix with a blend suitable for epiphytic plants. Be gentle when handling the plant during repotting to avoid damaging the delicate roots. Consider repotting every 2-3 years, and water sparingly in the initial weeks after repotting to aid the plant's adjustment.
