A sunny, well-ventilated aspect, a sharply-drained growing medium, heavy drenching at regular intervals during the growing season and maintenance of a dry period in dormancy are required for the successful cultivation of Tritonia crocata. It can be grown in containers, window boxes, rock garden pockets and as a front border to larger herbaceous plants. Plant the corms in autumn (April-May) in a sandy soil containing some well-decomposed compost, at a depth of about 2 cm of growing medium above the corm. Corms should be planted close together (about 5 cm apart) to create a massed effect. Allow the growing medium to dry our completely for the summer, or lift them and store in a cool dry place until autumn.

Sow the seeds in autumn in deep seed trays or pots, in a well-drained medium such as equal parts of finely sifted compost and coarse river sand. Cover the seeds with a 3-4 mm layer of sowing medium and keep moist by watering with a fine rose about twice a week, depending on weather conditions. Germination of fresh seeds takes place in about three weeks, and under ideal conditions, flowers can be expected for the first time in the second season.

The developing flower buds are sometimes attacked by aphids, and the foliage often falls prey to rust fungi in winter and to red spider mites in early summer. The corms are subject to mealy bug infestation when grown in containers under enclosed, poorly ventilated conditions.
