Water regularly to keep the soil consistently moist, especially during dry spells. Avoid waterlogging, as this can lead to root rot. Allow the top few centimeters of soil to dry out between waterings.

Reduce watering frequency in cooler months.

Prune Vicia elegantissima to maintain shape, remove dead or diseased stems, and encourage bushier growth. Light pruning can be done after flowering to prevent seed set and tidy up the plant.

Heavy pruning is usually not necessary unless the plant becomes overgrown or leggy.

Propagate Vicia elegantissima from seed. Seeds can be sown directly into the garden in spring after the last frost or started indoors a few weeks prior. Scarification of seeds may improve germination rates.

Cuttings are less common but can be attempted in spring or early summer.

Repotting is generally not a concern for Vicia elegantissima, as it is often grown as an annual or a short-lived perennial in the ground. If grown in containers and it becomes root-bound, repot into a slightly larger container with fresh potting mix in spring.
