How to Balance pH for Helichrysum Plants

Maintaining the optimal pH level in the soil is crucial for the healthy growth and development of Helichrysum plants. This comprehensive guide will walk you through the step-by-step process of balancing the pH for your Helichrysum plants, ensuring they thrive in the perfect growing environment.

Soil Testing for Helichrysum Plants

The first step in balancing the pH for Helichrysum plants is to test the soil’s current pH level. This can be done using a home soil testing kit or a professional soil analysis service. Helichrysum plants prefer a slightly acidic soil with a pH range between 5.8 and 6.2.

If the soil pH is too high (alkaline), you can lower it by adding amendments such as:

  1. Elemental Sulfur: Apply 1-2 pounds of elemental sulfur per 100 square feet of soil to lower the pH.
  2. Aluminum Sulfate: Use 1-2 pounds of aluminum sulfate per 100 square feet of soil to decrease the pH.
  3. Sulfuric Acid: Carefully apply a diluted solution of sulfuric acid to the soil, following the manufacturer’s instructions.

On the other hand, if the soil pH is too low (acidic), you can raise it by adding amendments such as:

  1. Limestone: Apply 2-4 pounds of limestone per 100 square feet of soil to increase the pH.
  2. Dolomite: Use 2-4 pounds of dolomite per 100 square feet of soil to raise the pH.
  3. Wood Ash: Sprinkle a thin layer of wood ash over the soil to increase the pH.

Monitoring and Maintaining the Optimal pH

After adjusting the soil pH, it’s essential to monitor it regularly to ensure it remains within the optimal range of 5.8 to 6.2. Use a soil testing kit or a pH meter to check the pH level every few weeks, and make additional adjustments as needed.

Factors Affecting Soil pH for Helichrysum

In addition to the amendments mentioned above, there are other factors that can influence the soil pH for Helichrysum plants:

  1. Irrigation Water: The pH of the water used for irrigation can affect the soil pH over time. Test the water pH and make adjustments if necessary.
  2. Organic Matter: Decomposing organic matter can lower the soil pH, so be mindful of the amount of organic matter added to the soil.
  3. Fertilizers: Some fertilizers can either increase or decrease the soil pH, so choose pH-neutral or pH-adjusting fertilizers as needed.

Ideal Growing Conditions for Helichrysum

In addition to maintaining the optimal soil pH, Helichrysum plants also thrive in the following growing conditions:

  • Temperature: Helichrysum plants prefer warm temperatures, with an ideal range of 65-75°F (18-24°C).
  • Sunlight: Helichrysum plants require full sun, with at least 6 hours of direct sunlight per day.
  • Watering: Keep the soil consistently moist, but avoid overwatering. Allow the soil to partially dry out between waterings.
  • Humidity: Helichrysum plants prefer low to moderate humidity levels, around 40-60%.


Balancing the pH for Helichrysum plants is a crucial step in ensuring their healthy growth and development. By following the steps outlined in this guide, you can create the perfect growing environment for your Helichrysum plants, allowing them to thrive and flourish.
