Daylilies are perennial flowers that grow throughout Alabama. Many older homes have established daylily growing beds. Site selection is an important factor before planting as the flowers require little care once established. The plants will grow in partial shade to full sunlight with an east, west or southern exposure. The soil must be somewhat fertile and well-drained. The root system on the daylily may rot if the plants are set into a wet area.
Break up the soil in the daylily bed with a rototiller to a depth of 6 to 8 inches.
Remove all rocks and weeds with the garden rake.
Mix in one bale of peat moss, six to eight cubic feet, per 100 square feet of growing bed to a final depth of 6 to 8 inches with the rototiller.
Broadcast 3 to 5 lbs. of the agricultural limestone and 2 to 3 lbs. of the 13-13-13 fertilizer for every 100 square feet of growing bed. Work the material into the soil.
Plant the individual daylily plants 18 inches apart in the growing bed. Dig the hole large enough so the roots are fully spread out in the planting hole. Keep the top of the root crown slightly below the top of the soil level. Water each plant into the soil immediately after planting.
Layer 2 to 3 inches of mulch around the plants. Fill in any bare areas between the plants with mulch to retain moisture and prevent weed growth.
Irrigate the daylilies during an Alabama drought.
Dead-head the old flowers with scissors as the outer petals fall from the plant. This encourages new flower growth. Remove all weeds that grow in between the plants. The daylilies will begin to fill in the open spaces in the bed during the second and third year of growth.
Mow the dead leaves with the lawn mower each year while the plant is in dormancy. Removing the top leaves will deter rodents from burying under the roots and eating them.
