To determine the current pH of your soil, you can use a home testing kit or send a soil sample to your local extension service. Home testing kits are readily available at garden centers and online retailers. Follow the instructions provided with the kit to accurately measure the pH of your soil.

How to Raise Soil pH for Balloon Flower (Platycodon)

If your soil pH is below 6.0, you will need to add lime to raise the pH. The type of lime you use depends on the current pH level:

  • For soils with a pH below 5.5, use dolomitic lime.
  • For soils with a pH between 5.5 and 6.0, use calcitic lime.

To apply lime, follow these steps:

  1. Calculate the amount of lime needed based on the current pH level. Apply 5 pounds of lime per 100 square feet for every whole point below the desired pH level. For example, if your current pH is 5.0, apply 25 pounds of lime per 100 square feet (5 x 5).
  2. Spread the lime evenly over the soil surface.
  3. Mix the lime into the top 6-8 inches of soil using a garden fork or tiller.
  4. Water the area thoroughly to help the lime incorporate into the soil.

If your soil pH is above 7.5, you will need to add elemental sulfur or aluminum sulfate to lower the pH. The choice of amendment depends on the current pH level:

  • For soils with a pH above 8.0, use aluminum sulfate.
  • For soils with a pH between 7.5 and 8.0, use elemental sulfur.

To apply sulfur or aluminum sulfate, follow these steps:

  1. Calculate the amount of amendment needed based on the current pH level. Apply 1 pound of sulfur or aluminum sulfate per 100 square feet for every whole point above the desired pH level. For example, if your current pH is 8.0, apply 1 pound of sulfur per 100 square feet.
  2. Spread the amendment evenly over the soil surface.
  3. Mix the amendment into the top 6-8 inches of soil using a garden fork or tiller.
  4. Water the area thoroughly to help the amendment incorporate into the soil.

How Long Does It Take to Balance Soil pH for Balloon Flower (Platycodon)?

After applying lime, sulfur, or aluminum sulfate, wait 2-4 weeks for the soil pH to adjust. Then, retest the soil pH to determine if further adjustments are needed. Repeat the process until the desired soil pH range of 6.0-7.5 is achieved.
