Caring for indoor cyclamen can sometimes present challenges, even to the most attentive plant parents. From yellowing leaves to pest infestations, understanding how to address common problems can help ensure your cyclamen remains healthy and vibrant.

1. Yellowing Leaves: Causes and Solutions

Yellow leaves on cyclamen can be caused by several factors, including overwatering, excessive heat, too much direct sunlight, or pest infestations. Here's how to tackle these issues:

  • Overwatering: Cyclamen prefer evenly moist soil. Let the soil dry out slightly between waterings and water from the bottom to prevent yellowing caused by too much moisture.

  • Heat and Sunlight: Cyclamen thrive in cool temperatures (50-70°F) and dislike direct sunlight. Move your plant away from heat sources and into filtered light to prevent leaves from turning yellow due to too much sun or heat.

  • Pests: Spider mites, aphids, scale, and mealybugs can damage cyclamen leaves, causing them to yellow. Check your plant for signs of pests and treat infestations with diluted natural insecticides or by wiping down with neem oil or insecticidal soap.

2. Cyclamen Mites: A Hidden Threat

Cyclamen mites are tiny pests that can cause significant damage, hiding in flower buds and new leaves. These mites thrive in high humidity and poorly ventilated areas. To combat an infestation, use a diluted natural insecticide and ensure good air circulation around your plants.

3. Propagating Cyclamen: Seeds and Root Division

Cyclamen can be propagated through seeds or by dividing the roots. Soak seeds for 24 hours before planting in spring, or divide tubers in the fall, keeping them in a protected place until roots form. Proper timing and care during propagation are crucial for successful growth.

4. Root Rot: Causes and Solutions

Root rot in cyclamen is primarily caused by overwatering and poor drainage, leading to a soggy soil environment where fungi thrive. The plant's base becomes mushy, and leaves may wilt and yellow.

  • Preventative Measures: Ensure your cyclamen is planted in well-draining soil and pots with adequate drainage holes. Water only when the top inch of soil feels dry to the touch, and avoid letting the pot sit in standing water.

  • Treatment: If you suspect root rot, remove the plant from its pot and inspect the roots. Trim away any blackened or mushy roots with sterilized scissors, repot into fresh, well-draining soil, and adjust your watering practices to prevent recurrence.

5. Fungal Diseases: Identification and Management

Fungal diseases, such as botrytis or gray mold, affect cyclamen leaves and flowers, causing them to rot. Poor air circulation and damp conditions often exacerbate these issues.

  • Prevention: Improve air circulation around your cyclamen and ensure the plant is not overwatered. Water at the base to avoid wetting the foliage, and consider using a fungicide if you frequently encounter fungal issues.

  • Treatment: Remove affected plant parts immediately to prevent the spread of the disease. In severe cases, apply a suitable fungicide following label instructions carefully.

6. Leaf Spot Disease: Causes and Solutions

Leaf spot, characterized by brown or black spots on the leaves, can be caused by both fungal and bacterial pathogens. It's often facilitated by overhead watering or splashing water on the leaves.

  • Preventative Measures: Water your cyclamen at the soil level to avoid wetting the leaves. Ensure good air circulation and practice crop rotation if planting in the ground or repotting.

  • Treatment: Remove and dispose of infected leaves to prevent the spread. For persistent problems, apply a fungicide or bactericide appropriate for the type of leaf spot diagnosed, following safety and application guidelines.

7. Dormancy Care Misunderstandings

Cyclamen's natural dormancy period can lead to yellowing and die-back of leaves, which is often mistaken for a health issue. This dormancy usually occurs after the flowering season.

  • Understanding Dormancy: Recognize that yellowing leaves during this time are normal. Reduce watering significantly during dormancy, and refrain from fertilizing.

  • Post-Dormancy Care: Once signs of new growth appear, resume regular watering and feeding to encourage the cyclamen to exit dormancy and begin a new growth cycle.

By addressing these common indoor cyclamen problems with informed care strategies, you can ensure your cyclamen remains a healthy and vibrant part of your indoor garden.

Fern's Leafy Learnings

  • Monitor Watering: Ensure cyclamen soil is moist but not soggy to prevent yellowing leaves.
