Plant Guide and Care Tips

  1. Lighting: Hoya Coronaria thrives in bright, indirect light. Place it near a window where it can receive filtered sunlight. Avoid exposing it to direct sunlight, as it may scorch the leaves. Insufficient light can result in leggy growth and reduced flowering.
  2. Temperature: This plant prefers moderate temperatures between 60°F and 80°F (15°C – 27°C). Protect it from extreme temperature fluctuations and cold drafts, as they can cause stress and leaf damage.
  3. Watering: Hoya Coronaria prefers slightly dry conditions. Allow the top inch of soil to dry out between waterings. Overwatering can lead to root rot, so it’s essential to ensure proper drainage. During winter, reduce watering frequency to prevent waterlogged soil.
  4. Humidity: Hoya Coronaria appreciates higher humidity levels, similar to its native tropical habitat. Mist the leaves regularly or place a tray filled with water near the plant to increase humidity. Alternatively, a humidifier can help maintain an ideal moisture level.
  5. Soil: Well-draining soil is crucial for the health of Hoya Coronaria. A mix of peat moss, perlite, and orchid bark provides excellent drainage. Avoid heavy, compacted soils that retain excess moisture.
  6. Fertilization: Feed your Hoya Coronaria with a balanced, water-soluble fertilizer during the active growing season (spring and summer). Dilute the fertilizer to half-strength and apply every four to six weeks. Avoid fertilizing during winter when growth slows down.

Common Problems and Solutions

  1. Aphid Infestation: Hoya Coronaria may occasionally attract aphids. To tackle this problem, spray the plant with a solution of water and mild liquid soap or neem oil. Repeat the treatment as needed until the infestation is under control.
  2. Leaf Spot: Leaf spot diseases can occur due to overwatering or poor air circulation. Ensure proper watering practices and provide adequate airflow around the plant. Remove infected leaves and adjust watering accordingly.
  3. Lack of Flowers: Insufficient light or improper pruning may inhibit flower production. Ensure your plant receives adequate bright, indirect light and avoid over-pruning, as Hoya Coronaria blooms on old growth.
