Safflower prefers well-drained soil and is drought-tolerant once established. Water deeply but infrequently, allowing the soil to dry out between waterings.

Avoid overwatering, especially during dormancy, as this can lead to root rot. Reduce watering as the plant matures and approaches harvest.

Pruning is generally not required for safflower, as it is typically grown as an annual for its flowers or seeds. Remove any dead or damaged foliage if necessary.

If the plant becomes leggy, light pinching can encourage bushier growth before flowering begins.

Safflower is easily propagated from seeds sown directly into the garden after the last frost. Seeds germinate readily in warm soil.

For a head start, seeds can be sown indoors a few weeks before the last frost and transplanted carefully, ensuring not to disturb the roots.

Repotting is not typically applicable to safflower as it is usually grown as an annual from seed sown directly in the ground. If growing in containers, select a pot that allows for adequate root development and avoid transplanting unnecessarily, as safflower can be sensitive to root disturbance.
