How to Balance pH for Yellow Archangel Plants

To maintain the optimal growth and health of your Yellow Archangel (Lamium galeobdolon) plants, it’s crucial to ensure the soil pH is balanced within the slightly acidic to neutral range of 6.0-7.0. This step-by-step guide will walk you through the process of testing, amending, and monitoring the soil pH to create the perfect environment for your Yellow Archangel.

Soil pH Testing

The first step in balancing the pH for your Yellow Archangel is to test the current soil pH. You can purchase a soil pH testing kit from your local garden center or online. Follow the instructions provided with the kit to obtain an accurate reading of your soil’s pH level.

Acidic Soil (pH below 6.0)

If your soil test reveals a pH below 6.0, you’ll need to raise the pH to create a more suitable environment for your Yellow Archangel. To do this, you can add lime to the soil. The amount of lime required will depend on the current pH level and the desired pH range. Refer to the packaging instructions for the recommended application rates.

Alkaline Soil (pH above 7.0)

If your soil test shows a pH above 7.0, you’ll need to lower the pH to bring it into the optimal range. To do this, you can add elemental sulfur or aluminum sulfate to the soil. Again, the amount needed will depend on the current pH and the desired pH level. Follow the instructions on the product packaging for the appropriate application rates.

Watering and Temperature

When watering your Yellow Archangel, use filtered water at room temperature. Avoid using cold water, as it can be a shock to the plant. Additionally, ensure the soil is well-drained to prevent waterlogging, which can lead to root rot.

Yellow Archangel prefers slightly acidic conditions and thrives in loose, fertile, and well-drained soil. It can tolerate medium to full shade in hot climates, but in cooler regions, it prefers some sun and light shade.

Monitoring and Adjustments

After amending the soil, retest the pH after a few weeks to ensure it’s within the desired range of 6.0-7.0. If necessary, make additional adjustments to maintain the optimal pH level.

It’s important to be patient when balancing the soil pH, as it may take several weeks or even months for the pH to stabilize after the initial amendments.


By following these steps, you can effectively balance the pH for your Yellow Archangel plants, creating the ideal growing conditions for their optimal health and growth. Remember to regularly monitor the soil pH and make adjustments as needed to maintain the perfect environment for your Yellow Archangel.
