To thrive, Stilbe vestita needs a well-ventilated, sunny position with well-drained, sandy, acidic soil. Feed with well-rotted compost and mulch once or twice a year. Slow-release fertilizer can also be used in diluted or small volumes. Pinching the tips of young plants generates a plant with more branches, a compact form, and more blooms. If properly hydrated, it can also be utilized in containers.

Seeds or cuttings can be used to propagate Stilbe vestita. Autumn is a good time to plant seeds (April to May). To enhance germination, treat the seeds with Instant Smoke Plus Seed Primer, a smoke-water solution, or expose the seed trays to the smoke of burning fynbos plants (in a tent). It is essential to use a well-drained, acidic sowing medium. Because the seeds are small, only a light layer of clean sand is required, or the seeds can be mixed with dry sand and put in a thin layer on top of the sowing media. To avoid moving the seeds, water with a fine rose, and keep the trays damp but not wet and out of direct sunlight in a warm but not hot place. Germination takes 1 to 2 months, and seedlings must be transplanted when they are around 10 mm tall.

In late summer to autumn, or in the spring, take semi-hardwood tip or heel cuttings. Apply rooting hormone and place in a sterile, well-drained, well-aerated, and well-ventilated rooting media. A root-stimulating hormone, such as auxin powder or IBA, is used to produce 50–70 mm long cuttings. Visible flower parts are removed before propagation, and cuttings are immersed in a seaweed extract solution and watered. The cuttings are planted in a substrate that is fynbos-friendly (such as a mixture of fine-milled bark and perlite). The surplus powder is allowed to stay on the cutting, where it will be inserted in the wet medium, by first creating a thin hole with a sterile wire and then placing the cutting in the hole. Before being placed in the propagation mist house, the cuttings tray is labelled.

The mist house is heated to a warm temperature of 22–25°C and sprays water for 5 seconds every 15 minutes to keep the rooting media moist and the leaves cool and moist. The bench is also heated and kept at a comfortable 22–25°C temperature. The cuttings are hardened off for a week in a shady place after 2–3 months before being potted into 2 kg nursery bags with a fynbos soil mix. They are regularly watered and given organic fertilizers once a month to encourage growth before being planted in the garden once they are ready.

Growing in sandy, acidic soil, Stilbe vestita demands a sunny area with sufficient air circulation. It's ideal for fynbos gardens, especially those located on damp, sandy slopes, or with a stream or seepage region in their garden . It enjoys warm, sunny, well-ventilated environments and has to be fed and watered on a regular basis during the summer. Mimetes, ericas, buchus, brunias, and restios are examples of companion plants.
