Water regularly, keeping the soil consistently moist but not waterlogged. Allow the top inch of soil to dry out slightly between waterings. Reduce watering in cooler months or if the plant is not actively growing.

Ensure good drainage to prevent root rot, especially in containers.

Pruning is generally not required for Lactuca virosa unless it becomes overgrown or develops damaged leaves. Remove any yellowing or dead foliage as needed to maintain plant health and appearance.

Pruning can also encourage bushier growth if desired.

Lactuca virosa is easily propagated by seeds sown directly in the garden or in containers in spring or early fall. Seeds germinate quickly in moist soil with light exposure.

It can also be propagated by stem cuttings, though this is less common.

Repot young plants annually or when they become root-bound, typically in spring. Choose a pot that is slightly larger than the current one, ensuring it has adequate drainage holes. Use a well-draining potting mix.

Mature plants may not require frequent repotting.
