How to Space Daylilies When Planting


Daylilies, or Hemerocallis, offer blooms from early summer to the first frost of fall. These self-maintaining plants will multiply quickly, so proper spacing is essential to optimal growth. The name daylily comes from the daily blooms. Generally, each flower lasts only a day, but the continuous nature of the blooms keeps the plant appealing for months.

How to Space Day Lilies When Planting

Step 1

Prepare the area where the daylilies will be planted. Till the dirt with a rototiller to a depth of 1 foot. Ensure the soil is loose and free of clumps. Add organic matter to sandy regions. Add dead leaves as compost to the soil and till until well mixed.

Step 2

Dig a hole 4 inches deep and 6 inches wider than the root of the plant. Mound some soil in the center of the hole.

Step 3

Set the plant into the hole on top of the small center mound. Spread the roots around the base of the mound. Examine the crown, the area where the foliage meets the root base, to ensure it is not more than 1 inch below the surface of the soil. Firm the soil around the plant gently to hold in place. Water well.

Step 4

Measure 18 to 24 inches from the plant and repeat the process until the entire area has been planted. Daylilies will triple in size each year, so proper spacing is essential. Never place plants closer than 18 inches apart.
