Perennial Plant Care Guide – Coneflower, Caralbells, Coreopsis, Daylily

Coneflower

To control weeds and retain moisture, apply a thin layer of compost each spring, followed by a 2 inch layer of mulch. These plants need watering during the summer if rainfall is less than 1 inch per week. To extend the flower period, deadhead spent flowers. However, in late-season, leave flowers on the plants to let them mature; the seedheads will attract birds. These plants need to be divided every 3 to 4 years in the spring.

Coralbells

Remove dead foliage, then, to control weeds and retain moisture, apply a thin layer of compost each spring, followed by a 2 inch layer of mulch. These plants need watering during the summer if rainfall is less than 1 inch per week. After bloom fades, cut back flower stalks. Plants need to be divided in early spring every 3 to 4 years or when the plant stems become woody or when the plant starts to fall open at the center.

Coreopsis

To control weeds and retain moisture, apply a thin layer of compost each spring, followed by a 2 inch layer of mulch. These plants need watering during the summer if rainfall is less than 1 inch per week. Tall varieties can be kept upright with a stake. After the first killing frost, cut stems back so that they’re 1 to 2 inches above the soil line. These plants need to be divided every few years in the spring.

Daylily

To control weeds and retain moisture, apply a thin layer of compost each spring, followed by a 2 inch layer of mulch. Avoid excess fertilizing; it will inhibit flowering. These plants need watering during the summer if rainfall is less than 1 inch per week. Remove individual spent flowers daily and cut back the flower stalks once all the flowers have gone by. These plants need to be divided every 3 to 4 years in the spring.
