How to Balance pH for Cyclamen: A Comprehensive Guide

Cyclamen is a beautiful flowering plant that adds a touch of elegance to any indoor or outdoor space. However, to ensure healthy growth and vibrant blooms, it is crucial to maintain the proper soil pH balance. In this comprehensive guide, we will walk you through the steps to effectively balance the pH for your Cyclamen plants.

What Is the Ideal pH Range for Cyclamen?

Cyclamen thrives in slightly acidic to neutral soil conditions, with an optimal pH range between 6.0 and 7.0. Maintaining the soil pH within this range is essential for the plant to absorb nutrients efficiently and prevent growth issues.

How to Test Soil pH for Cyclamen


Before making any adjustments, it is important to determine the current pH level of your soil. You can use a home testing kit or send a soil sample to a local extension service for accurate results. Here’s how to test your soil pH:

  1. Collect soil samples from various locations around your Cyclamen plants, taking soil from a depth of about 6 inches (15 cm).
  2. Mix the soil samples together in a clean container to create a representative sample.
  3. Follow the instructions provided with your home testing kit, or send the sample to a local extension service for analysis.

How to Adjust Soil pH for Cyclamen

Once you have determined the current pH level of your soil, you can take steps to adjust it if necessary. Here’s how to raise or lower the soil pH for Cyclamen:

Raising Soil pH (if below 6.0)

  • To raise the soil pH, you can add lime or dolomite to the soil. The amount required depends on the current pH level and the soil type. As a general guide, add 1 pound of lime per 100 square feet (0.5 kg per 10 square meters) to raise the pH by approximately 0.5 units.
  • Alternatively, you can use poultry manure to increase the soil pH gradually. Apply a layer of poultry manure around your Cyclamen plants, using about 1 inch (2.5 cm) of manure per 10 square feet (1 square meter) of soil.

Lowering Soil pH (if above 7.0)

  • To lower the soil pH, you can add elemental sulfur or aluminum sulfate to the soil. The amount needed depends on the current pH level and the soil type. As a general guide, add 1 pound of elemental sulfur per 100 square feet (0.5 kg per 10 square meters) to lower the pH by approximately 0.5 units.
  • Organic matter, such as compost or composted manure, can also help lower the soil pH over time. Apply a 2-inch (5 cm) layer of organic matter around your Cyclamen plants and incorporate it into the top 6 inches (15 cm) of soil.

Caring for Cyclamen to Maintain pH Balance

In addition to adjusting the soil pH, proper care practices can help maintain the ideal pH range for Cyclamen. Follow these tips:

  1. Plant Cyclamen tubers 1-2 inches (2-5 cm) deep, with the top of the tuber just below the soil surface. Space tubers 6-10 inches (15-25 cm) apart in well-draining soil enriched with organic matter.
  2. Water Cyclamen gently after planting, ensuring not to overwater or get water on the tuber to prevent rot. Maintain consistently moist but not waterlogged soil throughout the growing season.
  3. Feed indoor Cyclamen plants with a half-strength balanced liquid fertilizer every two weeks during the growing season. Outdoor plants typically do not require additional feeding unless grown in containers.
  4. Remove spent flowers and yellowing leaves regularly to encourage more blooms and prevent disease. Prune leggy growth to maintain a compact plant habit.
  5. Allow Cyclamen to enter dormancy after flowering by reducing watering and letting the soil dry out. Store the plant in a cool, dark place for 2-3 months before resuming watering to trigger new growth.

Home Remedies for Balancing Cyclamen Soil pH

In addition to commercial products, there are several home remedies you can use to balance the soil pH for your Cyclamen plants:

  • Coffee grounds: Sprinkle used coffee grounds around your Cyclamen plants to gradually lower the soil pH. Use about 1 cup (240 ml) of coffee grounds per plant, and repeat every 4-6 weeks as needed.
  • Wood ash: To raise the soil pH, sprinkle a thin layer of wood ash around your Cyclamen plants. Use about 1/2 cup (120 ml) of wood ash per plant, and repeat every 6-8 weeks as needed.
  • Vinegar: For a quick pH reduction, mix 1 tablespoon (15 ml) of white vinegar with 1 gallon (3.8 liters) of water. Water your Cyclamen plants with this solution once a month, monitoring the soil pH to avoid over-acidifying.

Monitoring and Maintaining Soil pH for Cyclamen

After adjusting the soil pH and implementing proper care practices, it is essential to monitor the pH levels regularly to ensure they remain within the optimal range. Test the soil pH every 3-4 months and make adjustments as needed.

Remember that balancing the soil pH is an ongoing process, and it may take several weeks or months to see the desired results. Be patient and consistent in your efforts, and your Cyclamen plants will reward you with healthy growth and stunning blooms.

By following this comprehensive guide on how to balance pH for Cyclamen, you can create the ideal growing conditions for these beautiful plants and enjoy their vibrant presence in your home or garden.
