Water this plant moderately when the top 2-3 cm of soil feels dry. Avoid overwatering, as Hackelia pinetorum prefers slightly drier conditions and can be susceptible to root rot if kept constantly wet.

Ensure good drainage to prevent waterlogged soil, especially during cooler months.

Pruning is generally minimal for Hackelia pinetorum. Remove any dead or damaged stems at any time. Deadheading spent flowers can encourage a tidier appearance, though it's not strictly necessary for plant health.

Avoid heavy pruning, as this can disrupt the plant's natural growth habit.

Propagation is best done by seed sown in autumn or early spring. Stratification may improve germination rates. Alternatively, division of established clumps in early spring can be successful.

Ensure seeds or divisions are planted in well-draining soil and kept consistently moist until established.

Repotting is rarely necessary for Hackelia pinetorum unless it has outgrown its container or the soil has become depleted. If repotting is needed, do so in early spring before new growth begins.

Use a well-draining potting mix and a pot that is only slightly larger than the current one.
