Keep the soil consistently moist but not waterlogged, especially during active growth. Water more frequently in warmer weather and less in cooler periods.

Avoid letting the soil dry out completely, as this can stress the plant.

Pruning is generally not required for this species, as it is a low-growing annual or biennial. Remove any dead or yellowing foliage as needed to maintain tidiness.

If the plant becomes leggy, a light trim can encourage bushier growth.

Propagation is easily achieved through self-seeding. Seeds are dispersed widely, often resulting in new plants appearing in subsequent years.

You can also collect seeds in late spring or early summer and sow them directly in the garden or in pots.

Repotting is typically not necessary for this annual or biennial plant. If grown in a container, it is best to allow it to self-seed and start new plants each year.

If you wish to keep a particular specimen, repotting can be done in early spring before significant growth begins.
