Plant 101: Hoya Kerrii – Sweetheart Plant

Exploring the Enchanting World of Hoya Kerrii

Welcome to my world of green wonders, where Hoya Kerrii takes center stage as the Sweetheart Plant or Valentine Hoya. As an enthusiastic plant lover, I’ve embarked on a delightful journey nurturing these heart-shaped beauties, and today, I’m excited to share my insights, tips, and personal experiences in cultivating the enchanting Hoya Kerrii.

Unveiling the Heartfelt Characteristics of Hoya Kerrii

Hoya Kerrii, hailing from Southeast Asia, is a member of the Hoya genus, celebrated for its distinctive heart-shaped leaves. These leaves, ranging from vibrant green to variegated shades of pink and white, add a touch of romance to any indoor space. The succulent-like, waxy texture of its leaves makes Hoya Kerrii an ideal choice for those seeking a low-maintenance yet visually appealing houseplant.

Planting and Care Guide for Hoya Kerrii

Light Requirements:

I’ve discovered that Hoya Kerrii thrives best in bright, indirect light. My personal recommendation is to place it near a north or east-facing window to ensure it receives the perfect balance of filtered sunlight. Avoid direct sunlight, as it can scorch the delicate leaves.

Temperature and Humidity:

According to my actual experience, Hoya Kerrii prefers average room temperatures between 65°F to 75°F (18°C to 24°C). It appreciates moderate humidity, and a simple misting routine or placing the plant on a tray with water and pebbles can create an environment it loves.


I’ve learned that allowing the soil to partially dry between watering sessions is key to Hoya Kerrii’s well-being. Stick your finger about an inch into the soil, and if it feels dry, it’s time to water. Remember, it’s better to underwater than overwater this delightful plant.

Soil and Potting:

Choosing the right soil mix is crucial. A well-draining potting mix formulated for succulents or cacti, comprising perlite, peat moss, and regular potting soil, works wonders. Opt for a pot with drainage holes to prevent waterlogging.

Common Problems and Solutions in Hoya Kerrii Care

Yellowing Leaves:

If you notice yellowing leaves, it could be a sign of overwatering or excessive sunlight exposure. Adjust your watering schedule and find a more suitable location with indirect light.


Like any other houseplant, Hoya Kerrii can attract pests. Regular inspections and, if necessary, treating the plant with organic insecticidal soap or neem oil can keep these pests at bay.

Leggy Growth:

Insufficient light can lead to leggy growth. Based on my experience, relocating the plant to a brighter spot or using grow lights can promote more compact and lush growth.

Tips for Healthy Growth and Blooming

  • Fertilize Monthly: During the growing season, I recommend fertilizing monthly with a balanced, water-soluble fertilizer diluted to half strength.
  • Provide Support: To showcase its cascading vines, offer support in the form of a trellis or moss pole.
  • Prune Selectively: Maintain a neat shape by selectively pruning and removing any yellowing or damaged leaves.
