How to Balance pH for Hemerocallis (Daylilies)

Maintaining the proper pH level is crucial for the healthy growth and vibrant blooms of Hemerocallis, commonly known as daylilies. By following these step-by-step instructions, you can easily balance the pH for your daylilies and ensure they thrive in your garden.

Soil Testing for Daylily pH

The first step in balancing the pH for your daylilies is to test your soil’s current pH level. You can purchase a soil pH testing kit from your local garden center or send a soil sample to a laboratory for a more accurate analysis. Daylilies prefer a slightly acidic to neutral soil pH, typically ranging from 6.5 to 7.0.

Adjusting Soil pH for Daylilies

If your soil test reveals a pH level outside the ideal range, you’ll need to make adjustments to bring it into the optimal range for daylilies.

Increasing Soil pH (Acidic Soil)

If your soil is too acidic, with a pH below 6.0, you can add lime to raise the pH. For every 1 square foot of garden space, mix in about 1/2 cup of dolomitic lime to increase the pH by 0.5 points. Incorporate the lime thoroughly into the soil and water it in well.

Decreasing Soil pH (Alkaline Soil)

If your soil is too alkaline, with a pH above 7.5, you can add elemental sulfur to lower the pH. For every 1 square foot of garden space, mix in about 1/2 cup of elemental sulfur to lower the pH by 1 point. Incorporate the sulfur into the soil and water it in thoroughly.

Improving Soil Structure and Fertility

In addition to adjusting the pH, it’s essential to improve the overall soil structure and fertility for your daylilies.

Incorporating Organic Matter

Adding organic matter, such as compost, well-rotted manure, or leaf litter, can help improve soil structure, increase nutrient availability, and enhance water-holding capacity. Aim to incorporate 2-4 inches of organic matter into the top 6-8 inches of soil before planting your daylilies.

Fertilizing Daylilies

Use a slow-release flower fertilizer or a natural organic plant food in early spring to provide essential nutrients for your daylilies. After the first round of flowers has spent, remove the spent flower stems and feed the plants again to encourage reblooming.

Maintaining Soil Moisture

Daylilies prefer a moist but well-drained soil. After planting, deeply soak the soil in the planting area to a depth of at least 6 inches. During the first active growth season, water only as needed to maintain a damp to moist root ball and surrounding soil.

Patience and Monitoring

Daylilies are resilient plants that can take some time to settle in and show their full potential. Be patient and give them time to establish in your garden. Monitor the soil pH and make any necessary adjustments as needed to maintain the optimal range for your daylilies.

By following these steps, you can effectively balance the pH for your Hemerocallis (daylilies) and create the ideal growing conditions for these beautiful and versatile perennials.
