Babiana ringens is a winter-growing species that is dormant during summer (December to February), actively growing during the cool, wet months (April to September) and entering dormancy during the hot, dry summer (November to December). This species makes an excellent addition to fynbos gardens and other rocky winter-rainfall gardens, and also fares well in containers. It prefers full sun and is able to survive temperatures down to about −5°C. The distinctive rat's tail perch and attractive red flowers of this feature plant create an unusual focal point. Plant in groups for best effect or combine them with other winter-growing corms that share similar cultural requirements.

Propagate Babiana ringens from seed or by dividing corms. Sow fresh seed in autumn (March to April) in a well-drained, sandy potting mix. Cover seeds lightly with soil and keep moist until germination occurs. Transplant seedlings once they are large enough to handle. Plants grown from seed typically take several years to reach flowering size. Plant corms in autumn at a depth of about 5–8 cm in nutrient-poor, sandy, gritty and very well-drained soil. Use neutral to acidic soil for optimal growth.

Water plants regularly from autumn through spring to keep the soil lightly moist. Water deeply at the root level and allow the soil to become almost dry between waterings. Fertilizer is generally not essential if the soil is well-prepared. If desired, apply a light application of all-purpose or high-potassium fertilizer in winter as growth begins. Leaves emerge in autumn (April), flowers are produced from late July to October, and seed capsules mature in late spring (October to November).

Do not cut the foliage after flowering. Allow the leaves to turn brown and die down naturally in late spring to early summer (October to November). This process stores energy in the corm for the next season's growth and flowering. Stop watering completely during the hot, dry summer dormancy (December to February) to prevent corm rot. In summer-rainfall areas or regions with hard frost (below −5°C), lift corms once the foliage has died back completely and store them in a cool, dry place. If desired, divide the corms and replant in autumn as the growing season begins.

Babiana ringens is generally pest-free when grown in well-drained conditions. However, like many cormous plants, it can be susceptible to several common pests. Thrips and red spider mites may attack the leaves, causing discoloration and stunting, particularly during dry conditions. Caterpillars can cause holes in leaves, while snails and slugs may feed on foliage and young growth. Mealybugs occasionally infest corms. Good horticultural practices, including proper watering and drainage, help prevent most problems. For severe infestations, use appropriate insecticidal soaps, horticultural oils, or targeted pesticides.
