Nerine filifolia is fast-growing, and bulbs multiply rapidly. It grows well in a wide variety of soils. Plant bulbs during spring in summer rainfall areas. Plant them where they will be exposed to full sun for most of the day. This will encourage the production of strong, straight, upright flowering stalks. They can be planted en masse, as a border to a mixed flower bed or along a garden path. They are also suitable for growing in containers in a sunny position, but ensure good drainage. They will survive with little water, but for a brilliant pink colour display in the middle of summer, it is better to water them regularly. If watered during the winter months, they will keep their leaves, otherwise the leaves will die off but will resprout the following spring. They can be cultivated by planting mature bulbs directly where you want them in your garden. Plants can also be propagated from fresh seed, but they will take much longer to flower. Plant the seeds in a suitable potting mixture and water regularly. The bulbs can be transferred to the garden after a year or two.

Unfortunately Nerine species, like many other amaryllids, are prone to attack by the amaryllis caterpillars. The plants should be regularly examined and action taken as soon as infestations are spotted, or else your plants can be totally defoliated and the flowers ruined. As a precaution, treat your plants regularly during the growing season to prevent them from being attacked.
