How to Prepare Soil to Grow Daylilies

Overview

Daylilies flower from June through September. Multiple blooms of yellow, orange, gold, purple, red or off-white are displayed on single long stems, some reaching heights of 4 to 5 feet . Daylilies can grow in just about any soil but, like most plants, if you enrich the soil content, daylilies will look healthier and fuller.

Step 1

Choose a well-drained sunny location. If a well-drained area is not an option, then raised beds can be used. Daylilies will bloom in partial shade, but with at least 6 hours of full sun, the flowers will appear in greater abundance.

Step 2

Test the soil pH level. Daylilies grow best in a soil pH level between 6.0 and 6.5. Soil pH test kits can be purchased at large home and garden centers or through your local nursery. Your local Cooperative Extension Office may be able to direct you to labs in your area that conduct soil tests for more comprehensive results (see Resources). Soil pH levels can be raised, if needed, by introducing lime into the soil according to the manufacturer's directions.

Step 3

Add about 2 inches of organic matter (compost, leaf mold or commercial organic compound) as you dig down 12 inches.

Step 4

Plant the daylilies at least 24 inches apart. A slow-release fertilizer in a 10-10-10 mix can be applied in the spring. Water after applying the fertilizer. Add 2 to 3 inches of mulch to help block weeds and retain moisture.
