- Division: Divide the plants in early spring or late fall. Carefully dig up the clump and separate the individual plants. Replant the sections in well-draining soil and water well.
- Cuttings: Take stem cuttings in late spring or early summer. Cut a stem from the parent plant, removing the lower leaves. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Keep the soil moist and the cutting in a bright, but not direct sunlight location. Once rooted, the plant can be transplanted into the garden.

Disease Management for Liatris punctata Hook.
Liatris punctata Hook. is generally a low maintenance plant that is resistant to most diseases. However, occasionally, it can be affected by several fungal and bacterial diseases that can impair its growth and flowering capability.
The plant might become infected with botrytis blight, a common fungal disease, which leads to the browning and blemishing of leaves, stems, and flowers. The disease is spread by moisture and requires proper air circulation to reduce. You can control it by spraying the plant with fungicide or by trimming out the affected parts.
Another common fungal disease that affects Liatris punctata Hook. is powdery mildew. The plant is infected with a powdery white coating that can be easily spread to neighboring plants by the wind. Regularly wetting the leaves can help manage the disease, and you should remove the infected areas and apply a fungicide spray for severe cases.

Liatris punctata Hook. is relatively resistant to most insect pests. Still, the plant can be attacked by some pests that can cause significant damage.
The most common pests that affect the plant are spider mites and aphids. Spider mites feed on the leaves of the plant and cause small dots or speckling on the leaves' surface. On the other hand, aphids can cause curling or distortion of leaves. You can easily control these pests by spraying the plant with insecticidal soap spray or Neem oil.
In conclusion, carefully monitor your Liatris punctata Hook. and look out for any symptoms of disease or pests early on to successfully manage any issue that may arise. A healthy plant will have less stress and thus will better resist any harmful agents that can affect its growth and overall wellbeing.
