Sichuan teasel prefers consistent moisture, especially when young and establishing. Water deeply when the top 2-3 cm of soil feels dry. Avoid waterlogged conditions, as this can lead to root rot.

Reduce watering in winter when the plant is dormant.

Pruning is typically minimal for Sichuan teasel. Deadhead spent flower stalks after flowering to prevent self-seeding if unwanted, or leave them for winter interest and wildlife.

Remove any dead or damaged foliage in early spring before new growth begins.

Sichuan teasel is easily propagated by seed. Sow seeds in autumn or early spring directly in the desired location or in pots. Scarification (lightly scratching the seed coat) can improve germination rates.

It may also self-seed readily in suitable conditions.

As a biennial or short-lived perennial that typically grows in situ and self-seeds, repotting is not a standard practice for Dipsacus asper. If starting plants from seed indoors or transplanting young seedlings, use a well-draining potting mix and a pot that allows for root development.
