Regular deadheading, the removal of spent flowers, encourages prolonged blooming and keeps the plant looking tidy.


A light shearing after the first flush of blooms can promote a second wave of flowering and maintain a compact, bushy form.



Propagation of the tickseed (Coreopsis ‘Jethro Tull’) is commonly achieved through division. In early spring, carefully dig up the clumps, ensuring that each division has roots attached, and replant them in well-prepared soil.

Seed Propagation

The tickseed (Coreopsis ‘Jethro Tull’) can also be propagated from seeds. Sow seeds indoors in early spring or directly in the garden after the last frost date for blooms the following year.

Container Popularity

The tickseed (Coreopsis ‘Jethro Tull’) is a sought-after plant for container gardening, offering a burst of color and texture to patio spaces, balconies, and small urban gardens.

Container Common Diseases

While tickseed plants in containers are generally less susceptible to soil-borne diseases, there are some common issues to watch for:

Root Rot

Overly wet conditions can lead to root rot in container-grown tickseed plants. Ensuring proper drainage and using well-draining potting mix can mitigate this risk.

Powdery Mildew

In humid environments, powdery mildew can affect tickseed plants in containers. Proper air circulation and avoiding overhead watering can help prevent this fungal disease.

Disease Diagnosis

Signs of Disease

  • Yellowing or browning of leaves
  • Stunted growth
  • Wilting or drooping foliage
  • Unusual spots, molds, or growths on plant surfaces

Common Pests


Aphids are sap-sucking insects that can affect tickseed plants. Regularly inspect plants for aphid infestations and use insecticidal soaps or horticultural oils as a control measure.

Spider Mites

Spider mites, identified by tiny webs on the undersides of leaves, can be a concern for tickseed plants. Managing moisture levels and using predatory mites can help control spider mite populations.

Botanist’s Tips


Applying a layer of organic mulch around tickseed plants helps retain soil moisture, suppresses weed growth, and moderates soil temperature.

Companion Planting

Pairing tickseed (Coreopsis ‘Jethro Tull’) with companion plants like coneflowers, salvia, and ornamental grasses creates visually appealing and ecologically beneficial garden displays.
