Water regularly to keep the soil consistently moist, especially during dry periods. Avoid waterlogged conditions, which can lead to root rot.

Allow the top few centimeters of soil to dry out slightly between waterings for established plants.

Pruning is typically not necessary for Taraxacum mattmarkense. Deadheading spent flower stalks can prevent unwanted self-seeding and encourage a tidier appearance. Remove any yellowing or diseased foliage as needed.

Taraxacum mattmarkense can be easily propagated by seeds. Sow seeds directly into the garden in autumn or early spring. They germinate readily in moist, well-drained soil.

Division of established clumps in early spring is also a viable method.

Repotting is usually only necessary if the plant becomes root-bound in a container or if you wish to divide it. This is best done in early spring before new growth appears. Use a good quality, well-draining potting mix.
