Charlock mustard prefers consistently moist soil, especially during its active growth phase. Water deeply when the top 2-3 cm of soil feels dry.

Avoid overwatering, which can lead to root rot, but also prevent the soil from drying out completely, particularly in hot weather. Reduce watering slightly once the plant has established.

Pruning is typically not required for Charlock mustard, as it is an annual plant that completes its life cycle within a single growing season.

If self-seeding is undesirable, seed heads can be removed after flowering to prevent the spread of unwanted plants. Otherwise, let it complete its growth and natural decline.

Charlock mustard primarily propagates through its seeds. Sow seeds directly into the garden soil in early spring or late autumn, as they require a period of cold stratification to germinate effectively.

Seeds can also be collected from mature plants and sown the following season.

Repotting is not applicable to Charlock mustard as it is typically grown as an annual directly sown into the ground or in containers from which it is not transplanted. If grown in a pot, it is usually allowed to complete its life cycle and then the soil is replaced for the next sowing.
