Lupins prefer consistently moist soil, especially during dry spells and when establishing. Water deeply once or twice a week, allowing the top few centimeters of soil to dry out slightly between waterings.

Avoid waterlogging, as this can lead to root rot. Reduce watering frequency in cooler weather and during dormancy.

Deadhead spent flower spikes regularly to encourage a second flush of blooms and prevent self-seeding, which can lead to leggy plants.

In late autumn or early spring, cut back the entire plant to basal foliage to tidy it up and promote vigorous new growth. Remove any diseased or damaged foliage as needed.

Lupins can be propagated by seed or basal cuttings. Sow seeds in spring or autumn after scarification or cold stratification for better germination.

Basal cuttings, taken from new shoots in spring, root readily in a gritty compost mix with bottom heat. Division is generally not recommended due to their taproot system.

Lupins are best grown in the ground due to their deep taproots. If grown in pots, choose a large, deep container to accommodate the root system.

Repotting is generally not needed frequently; only when the plant outgrows its container, typically every 2-3 years. Handle the taproot carefully to avoid damage.
