Balancing the pH for Orange Lilies: A Comprehensive Guide

Maintaining the optimal pH level in the soil is crucial for the healthy growth and vibrant blooms of orange lilies, particularly the Clivia miniata variety. This comprehensive guide will walk you through the step-by-step process of balancing the pH for your orange lilies, ensuring they thrive in your garden.

Soil Testing: The First Step

Before you can begin adjusting the pH, it’s essential to test the soil to determine its current acidity or alkalinity. You can purchase a home soil testing kit or contact your local extension service to have a sample analyzed. This information will be the foundation for your pH balancing efforts.

Lowering the pH (Acidic Soil)

If your soil test reveals a pH that is too high (alkaline), you’ll need to lower it to the ideal range of around 6.0. To achieve this, you can add elemental sulfur or aluminum sulfate to the soil. Follow the manufacturer’s instructions carefully, as the amount required will depend on the current pH and the desired change.

Raising the pH (Acidic Soil)

For soils that are too acidic, with a pH below 6.0, you’ll need to add lime to raise the pH. Again, consult the product instructions to determine the appropriate amount based on your soil test results and the desired pH level.

Ongoing Maintenance

Regular Watering

Consistent, well-timed watering is crucial for maintaining the optimal pH level in your orange lily’s soil. Ensure the soil drains well and water only when the top inch of soil is dry. Overwatering can lead to waterlogging and pH imbalances.

Use a balanced, slow-release fertilizer formulated for flowering plants. Apply the fertilizer monthly from March to October, but avoid fertilizing during the winter dormancy period.


If the roots of your orange lily have covered the pot’s surface, it’s time to repot the plant. Choose a pot that is approximately 0.79 inches wider in diameter than the previous one. Handle the fleshy roots gently, as they are highly sensitive.

Providing a Cold Stimulus

To encourage flowering, your orange lilies will benefit from a resting period of at least two months, from October to December, during which the plant is placed in cool temperatures between 50 and 53.6 degrees Fahrenheit.

Hardiness and Specific Needs

Remember that orange lilies, specifically the Clivia miniata variety, are generally hardy in USDA Zones 4 to 8. However, it’s essential to research the specific hardiness and care requirements of the particular lily varieties you plan to cultivate.

By following these steps, you can effectively balance the pH of your soil to create the ideal growing conditions for your orange lilies. With the right soil pH, consistent care, and a cold stimulus, you can enjoy the vibrant blooms and healthy growth of these stunning plants.
